The monitor goes out periodically for 1 2 seconds

monitor, goes, periodically, seconds

If, while working at the computer, you observe an involuntary shutdown of the screen, but the PC itself is working at the same time, the essence of the problem does not always lie in the monitor. The case may be a connection error, a malfunction of a video card or other components, as well as for a number of other reasons, but first things first. Below we will consider all the reasons why such a nuisance may arise.

Reason one. monitor malfunction

Since the monitor screen goes blank, but the computer continues to work, you should start by checking the most obvious cause of the malfunction.

First you need to turn off the computer, and then turn it on and watch the monitor.

  • When the PC was turned on, the monitor cleared up and immediately darkened?

Perhaps this is due to the backlight lamps installed in modern LCD monitors. They could burn out.

  • The monitor screen is dark, and when illuminated under a backlight, it is faded?

Most likely, the matter is in a malfunction of the voltage inverter.

In order to understand what is the true cause of the monitor malfunction, disconnect it from the system unit. If the inscription “No signal” or something similar does not appear on the screen, you cannot do it on your own. Repair can solve the problem, but in the worst case, you will have to buy a new monitor.

The second reason is a malfunction of the video card

If any component is faulty in the computer, it often warns about this when turned on by intermittent signals.

Disconnect the PC from the network, wait a few minutes, open the lid of the system unit and move the discrete video card a little (if you have one). Turn on your computer. If that doesn’t work, remove the discrete video adapter and connect the monitor to the integrated (on-board) video card.

If you haven’t cleaned your computer for a long time, it makes sense to do it now. It is possible that the dust that has accumulated in the system unit does not allow the video card or RAM to work correctly, causing it to fail. Disassemble your PC and clean it from dust. We recommend using a USB vacuum cleaner and a soft brush for this. This procedure must be done at least twice a year, but more often.

Reason four. cable damage

Quite a common cause of many computer malfunctions, but it is not so easy to notice it at first glance. Externally, the cable may well seem safe and sound.

You can check this in the following way: find a similar cable and connect it. If everything works, you know what the problem is.

Reason five. incorrect connection

or less modern computers have two video cards. integrated and discrete. If you or someone, without your knowledge, mistakenly connected the monitor to the wrong place, the computer simply will not see it, although it will show characteristic signs of life.

The fact is that in the BIOS settings, the default preference is given to a more powerful card, that is, a discrete one. In this case, when connected to the integrated video card, the monitor screen will remain black.

To solve the problem, check if your monitor is connected to the correct video card.

Reason six. malfunction of the processor or motherboard

In this case, coolers continue their work, thereby creating the illusion of a correctly working computer. Pay your attention to whether there is an intermittent beep when starting the PC, whether a mouse with a keyboard is highlighted, a USB flash drive.

The seventh reason. banal life situations

An absolutely serviceable monitor may well stop showing signs of life due to the fact that its owner or someone without his knowledge, by the wildest accident, turned off something. Be it the monitor’s power button, the cable for connecting it to the PC or the power cable, but if you are sure that everything should work, you definitely would not think to turn your attention to such trifles, but you should start with this.

Bottom line: before you panic, thoroughly check the power on / connection of the monitor.

That’s all, now you know exactly what to do if the monitor screen goes blank, but the computer continues to work.

The problem is this. During games, watching a movie, surfing the Internet, etc.
The monitor goes out (sometimes a strange sound is heard) and writes “no signal” and the rest of the PC components work (sometimes the entire PC is cut down, and sometimes it restarts). And that’s when the monitor just goes out, and the rest everything works. An orange light is on on the monitor, indicating that the monitor is only powered on, but when the monitor is turned off and on, the blue light comes on and the monitor itself lights up and says “no signal” and the orange light turns on and the screen goes out again. It turns on only if you completely turn off the PC and turn it back on.
What to do to solve this problem?

Hello, Alexander. I propose to exclude problems with a logical exception)

First try connecting the monitor to another PC or laptop using the same HDMI or VGA cable. If the problem persists, replace the cable. If after changing the cable the signal still disappears, then the problem is in the monitor device itself. Therefore, everything works well on your PC, the cable is also workable.

If after connecting to another PC the error disappeared, then most likely the problem is in your computer. If you have 2 video cards (built-in and additional, then change the priority of use in the graphics settings. It is possible that the problem lies in the breakdown of the used graphics processor. Well, that’s all that can be done for now).

Next, you will need to disassemble the PC for troubleshooting. Maybe the capacitor is broken or some other part. Because of this, a power surge occurs and the graphics are turned off so as not to burn out. Well, or something else)

The same problem, I just noticed that the processor cooler is also turning off

hello, too, the problem with the monitor goes out by itself, but when you watch a movie or play everything is fine. what can be?

The same thing. During games, all the rules and during normal operation are turned off or rebooted. You solved your problem ?

Good day. First, try reinstalling the video card drivers. in most cases this solves the problem.

If it remains, follow the elimination method. check the video card on another computer, if everything is working properly, then the power supply and the monitor itself.

Try to rule out the possibility of a software problem first (reinstall Windows and drivers), and then check the hardware.

Hello, I have a current problem. I enter any game, make the screen full and my monitor turns off. I can’t calmly have nothing to do while the monitor turns off only when I go to any game, no matter whether it is on the social network or not, if the game is on the social network, it turns off when it’s a 3D shooter. and if on the PC itself, then any! Please help me to solve this problem I am already tortured.

Check your graphics card. Most likely, it does not have enough RAM or internal damage to the device. What is your card model, what processor, how much RAM is on your computer.

I suspect the graphics card is overheating and shutting down. Maybe some wire has come off inside. Take the video card to a specialist for inspection.

Also a problem similar to asus vw246h, I play WOT in windowed mode, switch to full screen through altenter and black screen, but everything works and sound too, monitor off. on earned, but sometimes throws off into windowed mode, and rarely that everything is normal. I took the TV set, too, I connected the lcd via HDMI to the PC, everything was clear without any failures, then in windowed mode, then in full, at least a hundred times in a row, and everything is OK.
What can be with the monitor.

there was such a problem, I fixed it by setting a lower resolution in the game.

try to connect the monitor to the mat board and drive the PC on the internet. games, etc. give him more load. if the PC works and does not turn off, then the problem is in the video card, namely in the processor. there apparently the thermal paste has dried, try replacing the thermal paste, if the problem persists then you have a micro processor welded and then only a complete replacement of the vidyuhi.

Good afternoon, such a disaster. I bought a used video card R7 370 4gb, it came with a vga-dvi i adapter. I connected it through it and could not configure the maximum resolution (it simply was not there) thought there was a problem with the driver. Updated, dropped, nothing helped. Phoned the past owner and he said that the matter is in the adapter. I changed the adapter to vga-displayport, the resolution got up and everything works, but sometimes in games or when watching videos, the screen just goes out for a few seconds and then lights up again without any errors or extraneous sounds. Tell me what the problem is

It is precisely the use of adapters that is causing the problem. First of all, get a normal cable by removing the adapter.

The problem is that I’m playing (Total War Shogun 2) and after about three minutes my monitor goes out and only reboot helps. Although I play battlefield 1 and everything is fine. What is the problem?

“Check your video card. Most likely, it does not have enough RAM or internal damage to the device. What is your card model, what processor, how much RAM is on your computer.

my monitor goes out if it is at rest for several minutes, that is, they do not work on the computer

Change your power settings. This feature is configured under Control Panel Power Options. Here open the power plan and edit the parameter to turn off the display.

Thank you so much! Found the answer to my question.

display off parameters edited for 30 minutes but display turns off after 1 minute

sorry! found the answer It’s all about setting the PARAMETER

Lyudmila, your display goes into sleep mode or just turns off, after which you need, for example, restart your computer?

I have the same problem. Enrages. Recently appeared. For some reason I suspect that this is from the last update of Windows.

It is possible that device drivers conflict with the new OS. Update the firewood for the video card. Alternatively, try booting from Ubuntu or another Linux system. If the errors are corrected, then the whole problem is in the drivers.

And I have the same problem the PC works for 1 hour it happens 3, but then the monitor flashes sharply and writes no signal, while the PC buzzes and gives signs of life. The video card is the newest 1 day like the power supply, I can’t understand why such a problem appeared after installing Windows 10 by the way, although I’m not sure for sure since before that the PC was turned off for a month without a vidyuhi and a block, after a reboot, nothing is working normally block at 650 watts percents old 4 more nuclear quadro still and vidyuha 750ti can anyone help!

It is possible that the whole problem is in the video card. Perhaps it is overheating, it is unlikely, but it may be) The second option is that the firewood is in conflict, try to update.

No video card does not get warm, its peak is 45 degrees. Of course, I don’t know with firewood, but rearranging it 10 times does not help, maybe something else conflicts with the battery changed to the motherboard I thought the problem had disappeared, I worked literally a day the next day I didn’t even know what kind of trouble it was. An acquaintance told me that maybe because of a too powerful power supply, but something is not enough to believe, or maybe the motherboard flew? this could be?

Hello, my problem is this:
During games, everything goes fine, most often (this does not happen all the time) while watching YouTube videos.
First, the monitor goes out, then when the monitor is (black or gray, when) the video sound continues for 1-2 seconds, followed by the background sound signal (iiiiiiiiiuuuuuurururururu) and that’s it ……………
Further, the keyboard is on, the mouse is on, too, visually everything is fine in the system unit BUT
There is no response to any key, nothing
Please tell me what could be and how to fix it.
PS: I repeat that this is not always, it happens often, it happens rarely, but it gets very hot! Or it happens that you load something, and then (a gift)
Cry for help.

This must be brought to the master for inspection. The sound is most likely from the hard drive, but this is not accurate.

Hello! I have the following problem. at first the screen somehow strangely began to buzz, then the chick blinked and turned off, although the processor itself is working. When I checked the cords everything seemed to be normal. Maybe so you can tell me what it might be? Thanks

The video card may be damaged. Or, inside the monitor, a loop or some other element has come off.

I turn on the manitor, the screen turned on for 2 seconds and went out and without the manitor the same

And how do you see without a manitor that it goes out?) 0) 0)) lol

I really hope for help or at least good advice from experienced users and professionals in their field.

The problem is this: during games (average performance), the monitor suddenly goes out and the computer does not respond to any clicks. Every fifth time, coolers begin to buzz strongly. The video card is powerful (Geforce 780 3 Gb), so Football Manager 2017 and Civilization 6 should pull easily. Before the problems, she easily pulled the last GTA at maximum settings.

There are no problems with the temperature of all components, at rest they do not heat up above 35 degrees, but under load I have not seen a figure above 60. There is a powerful water cooling. When opening many browsers at the same time, watching movies and low-performing games, the problem does not arise.

I reinstalled the drivers on both the motherboard and the video card from the official site, in the end I even reinstalled Windows, but the problem remains. In the first minutes of games. the monitor goes out.

I’m afraid the problem is not in the wood, viruses or software, but in the hardware. Only that it can be a card, power supply, motherboard or RAM. How can this be determined?

I had the same problem with the NVIDIA GeForce GTX 460 graphics card before that I played Warface for 5 years and now it started

Good day. Have you tried reinstalling drivers?

the same nonsense with a new 1050 card, I gave it for repair, before that I lost the driver ((

Hello! Faced such a problem I bought a system unit for components (intel i5 6600 4x 3.3 ghz, gigabyte nvidia gtx 970 xtreme gaming, 2 × 8 Kingston Hyper Fury 2400Mhz, Asus Prime B250M-A. Aerocool PGS V3X case with 550W PSU). collected the components myself initially the computer turned on nothing was displayed on the monitor after several resets it started up. installing new firewood on the vidyuhu and the motherboard. playing games at max requirements after a while the screen goes out, while the sound of the game continues the system is new, just put it on a working monitor, there was no such thing on the last system unit the system really does not even have time to heat up (on a video card, power is needed in two ports of 8pins there was only 6 pins in the block, I put an adapter from 6 to 8 pins and put an adapter from a normal power supply to 8 pins)
Prompt plz what is the problem?

Uninstall the drivers completely and reinstall them. And a little more clarification. You installed the system already on a new system unit?

I have two colors of the light bulb on my monitor 1 orange when the PC is not on 2 light green when everything is working and 3 the lamp does not light at all when there is no electricity but the electricity is on the PC is off and all these colors are orange and then even if the PC is not on light green lights up and everything goes out colors and again orange, then light green and so on and does not show the desktop what to do?

Check the connection and integrity of the cables. Try connecting your monitor to a different computer. If a problem is observed with it, it is necessary to diagnose the monitor.

Guys need urgent advice, dial if it’s not difficult 0637573679 Anton problem of the century

Anton, describe all your problems in detail in the comments.

Help people to understand the cause of the laptop malfunction. Very often the screen goes blank, it turns black, the mouse does not respond, the keyboard does not respond, the cooler continues to work, the LED on the on / off key is on, the PC can be restarted only after disconnecting from the network. I cleaned the PC, changed the thermal paste, replaced the Windows, updated the drivers, everything is in order in the power settings. What could it be?

The problem may be in the laptop screen itself. If it is faulty, then only its replacement can help here.

Good day. There was a problem with your computer yesterday.
Noise appeared when starting the computer (like a tractor working). after 20-30 minutes the computer freezes. I disassembled the system unit, cleaned it of dust (as far as possible with improvised means (a regular vacuum cleaner). the video card fan was clogged. The noise stopped, but in 5-6 hours the computer “froze” twice. Or rather, it rebooted once with the appearance of a blue screen, the second time the screen went out (although the monitor burned as if it was on, but the computer continued to work. A forced restart helped.
Today I plan to clean it with compressed air. What other options could be and what is worth checking?
I would be grateful for the answer.

Finish cleaning the cooling and also replace the thermal grease of the video card.

greetings, I have an ancient beech model e machines E510. the book is working, the fan is humming. the monitar goes out immediately after 1-2 seconds of work, and sometimes it works 5-10 minutes and I have time to turn on any audio files? so what about it do? carry to repair or try to fix the problem yourself? please answer someone, tortured by this problemma.

Hello. Try connecting the laptop to an external monitor and unsubscribe if the laptop works like this or is still going out.

Such a problem
When you connect the monitor to the power, the light comes on and immediately goes out. Turn off the power, then turn it on again nothing works. After 10-15 minutes, connect the power again and the light turns on and off again. What to do? If both on the computer and on the laptop are also

Apparently the monitor is out of order.

Hello, such a garbage from a neighbor, the PC works a little, then bam and the monitor goes out and the PC does not react to anything, although the system unit itself does not turn off, neither the keyboard nor the mouse works, only after rebooting it is rebooted and again for 5-10 minutes and new.
what could be the reason?

Most likely the problem is related to overheating of the video card.

good day! when the games are turned on, the monitor goes out, but turning the monitor on and off through the button only helps for a couple of seconds and this is only in games Samsung monitor. I turn on another monitor there is nothing like that what could be the reason?

From what you wrote, we can conclude that the problem is with the monitor.

Hello everyone, such a problem, I play games and after a long game, if I get out of it, then I get a stupid black screen as if the signal is being sent with a vidyuha, I reboot and again the black screen and the speaker beeps 1 long. After 2-3 turns on, everything works again, but when you enter the game and long-term gaming, everything starts from the beginning.
Can someone tell me how to treat this?
My system:
I3 4160
Gtx 1050ti
RAM 4gb
Win 10
And there are also terrible sounds from the headphones, just like a dandy if you pull out the cartridge from it
I installed Windu clean yesterday
Thank you in advance)

It’s hard to say without diagnostics, but it is quite possible that the video card is out of order.

You are under warranty to repair your monitor free of charge. Get it.

Hello! also problems with the video card when the computer is turned on, the fan inside the game block begins to buzz, but the computer itself worked fine, but after 10-15 minutes the screen goes out and the video card starts to buzz strongly but does not write that there is no signal, I checked the video card inside the block when turned on, it is not known why, although the system unit itself served for at least 3 years, then this horror began, I don’t even know what to do to change the cooler, I looked at the video card for any damage, nothing was found, but I did not pull out the card itself, the screen itself turns off when I start itthat any game 3D,

It was not connected with the monitor, it worked well for like five years and continues again, but it all started with a video card and the screen works fine.

We cleaned the game block itself from dust not long ago, for at least a week, but the noise did not stop in the video card

The problem appears to be a malfunctioning video card fan. Alternatively, try replacing the cooler on it.

The problems started yesterday. The computer boots up normally, and after five to ten minutes the screen goes out, as if the signal had disappeared, but the computer continues to work, reacts to keystrokes. It can boot without an image, then it suddenly appears, then disappears again. This morning and afternoon the symptoms disappeared, I thought it had improved by itself, and in the evening the same thing happened again. What could it be?

First, try connecting your computer to a different monitor. If the symptoms disappear, then the problem is with your monitor.

Thank! Now it works again. If he starts to freak out again, I’ll probably call the master tomorrow. What he says, I’ll write here. Suddenly someone will come in handy.

Hi, the screen when working when it is 5 minutes when the hour turns black, also some stripes appear on it (a little), the system unit continues to work, but does not respond to any keystrokes, I restart the PC, the screen does not respond, the mouse starts blinking violently, the system engineer does not make any sounds that it has started, and the monitor behaves as if the system unit is turned off, it takes 2-4 hours for the PC to start again and the same situation repeats, the system unit has completely cleaned the dust (very clearly), changed the thermal paste on the processor and chipsets to motherboard.

Do you have a built-in or discrete video card? If discrete, then it is very similar to its overheating.

Good day! I have a problem like this. I turn on the PC, watch movies, surf the Internet, it doesn’t matter, everything is fine. I start playing the game for 3-4 minutes and the screen goes blank, although the processor works and there is sometimes a little noise in the speakers, and sometimes there is no noise. You have to turn it off and on again. Help!

If the game is pirated, then the problem may be in it. Try to find a different distribution kit and try to install and run it on your computer.

Hello !! I have such a problem I go to the Internet and the monitor fades out for 2-4 seconds, then turns on and again the same way, and after 2 minutes everything is fine what to do

Test the monitor for functionality by connecting to another computer.

Hello! The problem is this. Playing games. I watch videos on YouTube and then bam and the monitor goes out, but the sound still works for 30 seconds. Then the computer turns itself off. When turned on, it turns out that it was a sleep mode. And you just need to lock the computer. This happens about once 1-2 hours. What to do? This is already starting to annoy.

Try to check your computer for virus activity first. If it does not help, unsubscribe.

I checked. There was 1 threat in Avast, I seem to have exterminated it. But in another antivirus program, as many as 3265, I quarantined them. But everything goes on!

And by the way, I’m 80% sure that these are viruses, maybe it all started on the day when the house started in the browser. The pages themselves were opened, the videos were reloaded, the pages were closed. And the calculator itself opened.

Alternatively, I can recommend performing a system restore to the period when there were no problems with the computer. If you don’t have a suitable rollback point, it’s best to do a clean install of Windows.

Good day! I have a problem like this. Regardless of the computer operating mode, the screen turns black for 3-5 seconds, often in series with an interval of 15-20 seconds. But I noticed that first the twitching of the screen and then small thin stripes portends this. This happens after different times, it can go out 10 times in an hour, or it can be all right for weeks. On fps In games, it does not affect how. Vidyuha GTX 770. 600W power supply, percent i5.2500K.3.30 GHz. 8Gb operative.

Anything can be here: a monitor, a virus, a driver, an incorrectly set display mode.

Hello. I’ve read a lot of things and still can’t solve my problem. The monitor screen goes blank. The tendencies leading to this are the following: When idle, when the PC is simply turned on and nothing is done, everything is normal. this is a desktop. As soon as you turn on the movie or just sit on the internet, it just turns off with a strange sound uuuuzhzhzh (and that may be after 15 minutes, or even after 1 hour), the screen turns off, but the power button is on, as if it is on, the PC continues to work.
Rearranged Windu. did not help. I reinstalled the driver. it did not help. The cable rearranged DVI to HDMI, even connected a TV set via a different cable. even the TV set goes out (so we exclude the monitor?)
I suspect that the video card (but can it really die like that?)
I also want to exclude the power supply. from its dying there may be such symptoms?
The hardware is the following. GTX 760 2 gig JeatStream PAlit video card FX 8320 4.5 GHz processor (it was overclocked, but changed to 3.5 GHz and still did not help) 650 watt power supply. This has been going on for about 1 week and more and more often.

Hello ! the problem is, when I turn on the computer, it shows an icon for me, but then the upper right corner starts blinking. Then it darkens, tell me what happened !

Hello! Tell me the solution. Unknowingly, the girl wiped the monitor with a window cleaner, after that the monitor began to work unstably, turned off by itself, the buttons stopped working, sometimes they work and sometimes they don’t, and sometimes the brightness adjustment window pops up, which was removed only by clamping different buttons on the monitor, so it was such that while I was holding this button, the monitor worked, and when I released it, it was cut down. Can this problem be repaired in a workshop, will it be expensive to repair?

In the monitor, you most likely have stuck power buttons.

Help me please!
I faced such a problem: the other day I was playing a game, the monitor went out abruptly, the light on it indicated that it was in working order. When I restart the computer, the Windows boot screen appears, the field in which you need to enter the password, and then the monitor turns off again. Sometimes it can take a couple of seconds after turning on the computer, and sometimes about an hour, but the result is always the same. the monitor goes out.

Anastasia, try booting from Safe Mode (to do this, at the earliest stage of the computer boot, press the F8 key repeatedly, and then select “Safe Mode”). If the download was ok, most likely there was some kind of system conflict in the system, for example, conflicting software, malfunctioning video card drivers, etc. Here you can advise to perform a system restore to the point of rollback when the computer was working normally (for this you should go to the menu “Control Panel”. “Recovery”. “Start System Restore”).

If there is no suitable restore point, I recommend reinstalling the operating system. If this does not help, perhaps the problem lies in the hardware component. monitor, video card, hard drive. Here you will need to check the performance of computer components (just connect to another PC).

Recently started. I played bioshock. Things are good. At the end of the game, the monitor went out. The system manager works in the same mode. Violently restarted. I installed an old stalker of the shadow of Chernobyl, which I played without problems on a dead PC 8 years ago. And the same thing happens. the monitor is cut down, the system unit works. I’m shocked! Help!

Determine if the problem is in the monitor or system unit. connect the monitor to another computer. If the monitor is working properly, most likely the problem needs to be looked for in the video card.

Hello, the problem is this: I go into the game, let’s say Call of Duty World of war, I start playing and after 1 to 3, the screen goes off, (energy-saving mode) I can’t restart, turn off the current button behind the block (I know that this cannot be done), no other way.
and just recently played the game The Walking Dead Survival Instinct normally, nothing went out, did not play for 2 weeks, went in and voila, goes out. It’s strange that this happens, everything seems to work, and then all the same, sooner or later, the monitor starts to go out on the game, which was normally loaded.
what could it be?

Most likely the problem is overheating of the video card.

good day!
I have an ASUS n550 jk nutobuk, an LG l192ws monitor. Recently I ran into a problem when the laptop is turned off for a long time or in sleep mode for more than an hour, then when you turn on (exit from sleep), the monitor turns on for a second and goes out, and the laptop itself works, there are system sounds, and even if you look closely, you can see the desktop, those. the screen itself goes out but not one hundred percent. I did not find such problems in the internet. I tried many ways: I updated the firewood from the office. site for the video card, the rapid storage technology driver has been updated, the power supply parameters have been checked, in the device manager, too, all the rules. Help me solve please.

And I also forgot, the temperature regime is normal, the motherboard percent video and SSD are in a temperature regime of 40-50 degrees.

It looks like your screen backlight is turning off. Check power settings. If your laptop has built-in screen customization programs, you should check the settings in them as well.

I checked this, at the very beginning, power settings wherever necessary “never” stands, there are no built-in programs for setting up the screen either. The strangeness is, as I already said, that the screen turns off when you turn on or wake up from sleep for 5 minutes, i.e. the picture appears for a second and then a dark screen (not black), I press ctrl alt del, the picture appears for a second and the screen goes out again, I repeat after 5 minutes and everything works, and then, at least as long as you sit with the computer on, the screen does not go out and works smoothly.

I have a problem like this:
I go into any game (downloaded, not in the browser) and when I play, the screen immediately crashed and the screen turned off, but the PC worked and it was impossible not to open the task manager, not go to the desktop, what’s the problem? (

Hello. To get started, you can try reinstalling Windows to eliminate three causes of the problem: power settings, video card driver malfunction, and virus activity. If it continues after that, check the temperature of the laptop. it is quite possible that it needs cleaning for a long time. And, finally, no one excludes the possibility that the screen or other component of the laptop begins to fail (here it is already necessary to carry out diagnostics at the service center).

Good afternoon! The fact is that the system unit itself does not work, at first I thought that I did not connect the “Hard” disk correctly, but looking on the Internet, I connected everything correctly. The system unit works, but the mouse, keyboard and monitor are not. What to do with it ?!Answer please!

If you turn off the monitor itself and turn it on, it shows the same for 5 seconds and then goes out again. LCD monitor Samsung. At the same time, the system unit continues to work. Help advice.

If possible, connect the monitor to another computer to determine if the problem is or not.

Good afternoon, such a problem, I can’t understand what is the reason, everything seems to be fine, but when I start playing Dota2, sometimes everything is fine, but often the screen goes out and sounds are heard for a while after the consumption. the system unit does not turn off but the power supply and the video card are warming up, although the video card itself is such a radeon nd6950 2g like they like the temperature. I have a question if it could be that the power supply simply does not supply the required voltage to the video card from which it starts to turn off the monitor thanks in advance

Yes Easy. If possible, try connecting a more powerful power supply.

The article turned out to be very relevant, after cleaning the video card everything worked !

Hello, I put an old monitor, it does not go out So something is wrong with the monitor ?

Hello! I have a slightly different problem. Why is it that when the computer is in standby mode (that is, the screen goes out when you do not use it) it does not turn on again. Although it should be rebooted when moving the mouse (not always) (the PC seems to work at the same time)

Hello. Try turning off the automatic display off and going to Sleep mode. This can be done in the menu “Control Panel”. “Power supply”.

Good day. I read the problems of people from above, but it seems like I did not see such a problem as mine. In general, the matter is as follows: This lasts 4 days already for the last (before this half a year there were no problems at all), I play DIFFERENT games, from fifa to warface, from 5 seconds (starting the game) to 30 minutes of work during the game itself, and bam. the monitor turns OFF, writes that there is no contact, the sound stops (in parallel I tried to turn on music in VK, it also immediately stopped playing), it turns out as if some kind of emergency vis, BUT the whole process inside the computer continues to work, all coolers turn like nothing happened, everything works, absolutely all fans continue to work. I press the shutdown button, the PC turns off. The last time I tested it, I played for 27 minutes and everything is the same, BUT already with the shutdown button I could not turn off the PC. I had to cut it through the power supply. I checked the temperature in the GPU-Z during the game, keeps it normally from 70 degrees to 85, once noticed, it went up to 92 degrees and after 2 minutes the PC knocked out (I think it’s a coincidence), because this is a single case, and it seems like 92 degrees is still not critical indicator during the game. On a cold, when working on the Internet or watching movies, the temperature is 35-40 degrees, that is, everything is fine with the video card and I think there can be no overheating. Geforse gtx 570 video card. What could be wrong? I cleaned the dust, it did not help, I checked the motherboard, all the rules. Help please, I don’t know what to think anymore. If it was a power supply, then probably the entire PC would be cut down just right away, right? And inside my work process is active and continues to work the same.

Hello, please tell me I have such a problem. I go into the game, the monitor goes out, the light does not light up, but the system unit is working and there are sounds, too, then after about 5 minutes it lights up. When you leave the game, it goes out again and again the light is off, but the system unit works and there are sounds too, then after 5 minutes it turns on again. During the game, it also turns off after 5 minutes. I have already tried everything and changed the firewood, cleaned the wire system, revised nothing, it does not help. Tell me what could be the problem. When you watch videos or movies, it does not turn off, and when you play games, even the most weak ones turns off and lights up again. Even online games are also turned off.

Try to connect any other monitor to the system unit. If everything is ok, the problem is with the monitor.

Hello. After the monitor has worked for 10-15 minutes, it goes out but not completely, when pointing the lamp, a faded drawing is visible, help me what to do. I connected another monitor, everything works.

We won’t be able to help here: the problem lies in the monitor, so if possible, take it to the service center (if it is still under warranty, the repair will be performed free of charge).

Good afternoon, the problem with turning off the monitor in games, asus z170 / i 5 6500 / ddr 4.16 gig SSD HDD but the video card is an old 660 Ti, but the problem in 2 games, the rest work fine, the system reinstalled the drivers updated t in games does not exceed 85

When I turn on the PC, exclamation marks appear on the monitor, then it writes select the version of Windows, and then it goes out, what to do?

In this case, the problem is not with the monitor, but with the operating system. If nothing happens after selecting it, reinstall Windows.

Hello, I have such a problem on the PC, the desktop is displayed and the screen blinks without interruption, i.e. it turns black for 1, 2 seconds and then back in a few seconds because of what I wanted to ask and the drivers in this PC are probably outdated and the RAM here is 2 GB dust may also interfere, but does anyone have any practice on this?

Good day. First, check if the problem is with the monitor. connect it to another computer.

Hello! There was a problem. I am working online, after the last Windows 10 update, the screen goes blank when working in the browser It can work for 5-6 hours normally and then it goes out. I saw this only in a browser, and anyway. I call the task manager, turn off the browser and everything continues to work normally. Intel (R) HD Graphics and NVIDIA GeForce 920M.

Good day. It doesn’t look like the browser might be causing a detailed issue. Try to check the power settings.

Hello. I have such a problem. Everything was fine until three days ago the computer screen went blank. Then after 2 hours after switching on, then 5 or more hours. And he could work normally for a day. and the stalemate goes out again. Writes. (no signal). Mouse keyboard does not work. Until you reboot on the processor itself. Reinstalled drivers. Deleted the entire program. Reinstalled Windows. The day worked fine and started to go out again. Sometimes the processor starts humming loudly. but not for long. What is the reason I do not know.

Hello. First, check if the problem is in the monitor or in the computer. To do this, if possible, connect to another computer. If the problem persists in this case, the monitor should be returned to the service center.

If you find that the problem is in the system unit, see if it is overheating: most often, a sudden shutdown of the computer occurs due to overheating caused by the accumulation of dirt and dust.

Your site is not opening or you cannot log into your mail account?

Hello, there is a problem with that. that when watching movies or games, the monitor turns off and the coolers on the video card start to work at the most powerful mode, I checked the monitor, the cable, checked the RAM, changed the video card and cleaned the computer, but the problem remained.?

Maybe someone can. There was a problem after launching any toy after 15 minutes, and when and after an hour the monitor went out and, interestingly, the keyboard was cut off. Before that, there was a virus on the computer. I cleaned it out with krait, immediately checked the registry and hard drive for errors. Did not help. I started to deal with the hardware, too, everything turned out to be fine. Killed three days for all this. And the problem turned out to be trivial. It was stupid to reset the BIOS. For the third day, everything is fine.

Good evening. Such a problem: when I turned on the desktop computer (Windows 10), the monitor managed to see the update is in progress. Then the screen went out and did not open any more. To see the desktop., I have to turn off and on the monitor every time., The desktop is shown for 2 seconds and then goes out again. 2 seconds is enough for one mouse click. And so many times. The monitor itself is working signals are going. Only the screen goes out. What can it be? Thanks in advance

Hello. Try to enter Safe Mode if there is no problem. a problem with the drivers. If the problem persists, go to BIOS. If in this case the image works correctly, the system update is probably crooked, here you can try to perform either a rollback, or even reinstall Windows.

My problem is this, I turn on the PC in the system unit, everything works, I installed a new video card, a power supply, checked all the wires, wiped all the RAM and motherboard with an eraser, removed the battery, the mouse is on, but the keyboard does not, and the main problem is the screen does not work, when you turn on the PC on the screen pops up the inscription “no signal” and that’s it. What to do? But all your advice above did not help me, I checked all the connections, changed the wire on the screen leading to the video card.

Hello. Try using a different cable to connect the monitor to the computer. It will be even better if you try to connect your system unit to a different monitor.

Hello. Our problem is that when the computer is turned off, the monitor itself turns on white and until you turn it off completely from the power, the monitor does not turn off. Then we turn on the PC, the monitor functions normally, and turn off the PC completely after a while history repeats itself. And now even the lamp on the monitor does not light up, and if you turn on the PC, the monitor does not turn on. All!

Irina, from what you said, we can conclude that the problem lies precisely with the monitor. To be sure of this, connect the monitor to another computer. If everything is still. either take the monitor to the service center, or replace it with a new one.

I have a problem like this:
Recently (about 2-4 days ago) I noticed that the monitor started to turn off and after 1-3 seconds it turned on again. This is done when I watch broadcasts, video. It just turns off and turns on immediately. In games like CS GO. in the main menu or when I am looking for a game, I left, came, the monitor is turned off again, while in the game itself, when I play and move the mouse, I did not notice that it would turn off. When I still go into the task manager, that I would turn off the game through it, my screen (desktop, etc.) is very close, as if the resolution flew off, but then everything falls into place, most often when I watch some videos, this is very strongly interferes. I am waiting for an answer!

Try reinstalling your graphics card drivers. If the problem appeared not so long ago, you can try to roll back the system (“Control Panel”. “Recovery”).

It didn’t help, the video card drivers were updated, but the problem remained.

Have you tried to restore? It looks like permission issues, as if some software is changing it on the computer. Before the problem appeared, what did you install?

No, but he writes that there are no restore points. Installed CCleaner and CS: GO 1.6.CS: GO removed, but at the same time I installed cheats, but then checked everything with Avast antivirus, full scan.

No, there is definitely no software here, because the screen turns off only when I watch a video, if I am sitting there in VK, then this is not there, but in CS GO the same way, if I, for example, walked away for 2-3 minutes, then the screen turns off and does not turn on again until you go into the task manager and turn off the game itself, but at the same time everything remains, that is, the computer does not turn off, only the screen goes out.

Look, maybe it will help you, this is what happened now, but I see it 1 time. Also, during the game, terrible lags and noises suddenly started, there were just such noises, but after 6-7 seconds it passed.

Right now I was watching the video, now my screen is off altogether, everything is black, but you can turn off the video, etc. That is, everything works, but the screen just turns off

This is clearly software. If reinstalling the drivers did not give results, it is better to rearrange Windows right away.

So this is not a monitor and not a system unit, and everything included in it?

Well, there cannot be such software that only when video and a game. if you are afk-shish for 1-3 minutes the monitor is off, if it was a virus, it would turn it off all the time, obviously it seems to me it’s either a monik, or a system unit, vidyuha, etc.

Software is easy, especially if a pirate has been installed. I will put the monitor in second place. That is why I advise you to first reinstall, in order to either confirm that it was in the software, or, conversely, to exclude this reason in order to already think about the hardware.

This means that there is no way to do without reinstalling Windows.?

Hello! I have such a problem: when watching any video in full screen mode, the monitor goes blank, in toys (any), even in social media. networks. the same story. (At the same time, the system unit continues to work. there is sound and all that stuff) the screen goes out first for a couple of seconds, but if you do not pay attention to this, the duration of the screen shutdown increases, and the interval between shutdowns decreases. once it turned off completely, even the desktop could not be called up, it also did not work to restart the button, I had to turn it off completely. connected the monitor to another computer. it works! changed the connection cords, rebooted the drivers. nothing helps. the video card, motherboard and processor are new, they were changed in December before the new year, but the monitor is old. Tell me, what could be the catch? PCI.E graphics card AMD RADEON RX 550 processor Intel Core i3-8100 motherboard ASUS LGA1151

Hello. How long does it take when connected to another PC? Perhaps the monitor itself is dying. After it turns off, if you turn off and turn on the monitor itself, and not the computer, does the picture appear?

Hello! We didn’t time the time, but when I connected another monitor to my PC, the problem persists, so it’s not the monitor? in general: you can’t guess when and how it will work. today, for example: I spent the whole day in classmates in a toy, began to “show off” only in the afternoon. and even then. rarely and not for long, but now I went into the Sims. after a couple of minutes the screen went out. I call the task manager to go to the desktop. everything works! I go into the toy. the screen immediately goes out again and does not turn on

READ  The screen does not go out when talking Honor

Then, indeed, the problem is in the computer itself. If you can, do a clean install of Windows to see if the problem was software or to confirm that the problem was in the hardware. If the second is confirmed, then, first of all, it is necessary to check the video card for operability (the link is given in the article).

Hello! I have a monitor connected to a video card through an adapter (display port), it may be such that the point is in it?

Hello! I have a monitor connected to a video card through an adapter (display port), it may be such that the point is in it?

For me, it goes out only when I do not move the mouse, that is, when I kind of afk (go somewhere) or watch a video, then I will not move the mouse, but just lie down and watch it, then it is only off and on what to do?

Try to open the “Control Panel”, go to the “Power supply” section. In the left part of the window, open the “Display off settings” tab and set the required parameters. If it does not help, try to select the item “Configure the power scheme”, and then click on the button “Restore default settings for the scheme”.

Hello, I have a problem, when I afk (do not touch the mouse), the monitor dims, becomes dark blue, the computer is working. This is definitely not turning off the display (sleep mode). I connected another monitor (with a different cable) to the system unit, the situation was the same, I changed the video card. it did not help, the screen still turned off (it turned dark blue). The only thing when the monitor did not turn off is when watching video files installed on the computer. Do not tell me how to solve the problem with the monitor?

All the same, it looks more like either the changed power supply parameters, or the operation of the software. Try to start by resetting the power profile settings in the “Control Panel”. “Power Options” menu. If the problem appeared not so long ago, so as not to waste time on finding out the reasons for its appearance, you can try to roll back the system through the menu “Control Panel”. “Recovery”. “Start System Restore”.

If you are sure that the reason is in the software, and restoring to the point when everything worked fine, did not bring any result, you can do it radically. reinstall the system.

Good afternoon! My problem is that the computer monitor turns on, but then a sign pops up: Nu a fost detectet un semnal And turns off. But the computer itself continues to work. I tried to translate, it did not work (.

Good day. This text is in Romanian. The message says there is no signal, so check the connection of the monitor to the system unit.

And I have some kind of obscurantism, I will be very grateful if someone tells me what the problem is. Problems started on the old PC first. He has seen a lot, lived for 7 years with power outages, moved from place to place, sometimes gave out artifacts, the screen went out. At first, the motherboard failed, the PC simply did not turn on. We replaced it, the processor remained old (AMD), after the motherboard, after a couple of days, the screen became covered with a grid and went out. Replaced the video card and power supply unit. All the same, periodically, when watching vidos on YouTube, the screen went out. Graphics card temperature

PC still works, but life without YouTube got me, and I bought a new one.
The new Dell, with two video cards (one built-in intel, works from a discrete one), is connected to a UPS, from the old one there is only Photoshop, on which I mostly spend my time. Again, the screen goes blank periodically. The monitor says that there is no signal. The cable is new. Sounds are emitted, as if the device is disconnected, the PC itself is working, but it does not show anything. I tried to connect to other monitors, the problem remained. While the reboot helps, sometimes it turns off for just a couple of seconds. Diagnostics on the manufacturer’s website does not show anything.
It already seems that “the reason is not in him, but in me.” But I don’t do anything on it at all. I turn on Photoshop, at most I watch the video in the second window. Once the PC could not shut down due to a frozen process from a buggy Photoshop, then reluctantly turned off the button. Well, in general, I don’t know where the problem is. Maybe someone came across something similar?

Do you have a computer or laptop? The operating system was rearranged? Couldn’t the problem be a hard dim?

Both computers are stationary. On the old one after replacing the motherboard, they did not reinstall it. On the new hard drive, it definitely has nothing to do with it).

Good day everyone!
A very strange phenomenon occurs at work, in workplaces. In general, the situation is as follows:
There are about 17 working computers in the office, or rather nettops, they worked on Windows xp. Recently, first one of them began to disappear into the black screen, a few more days later two more. The nettop itself is working, and the screen is black and the indicator is flashing. At first I thought I went into sleep mode, but no. Reboot, it works for an hour or two, and again the black screen. We changed nettops, the situation is the same. We changed the monitors and all the cables, there are no changes, just an hour or two and a black screen. As a result, the other day we put problematic monoblocks on these 3 places, installed Windows 7. And oops, again a couple of hours of work and went out again. Can someone tell me what kind of anomaly is going on. )

Hello, it seems that this is not about devices. It is more logical to assume that the problem is in the UPS, if any, in the voltage.

Good evening, I have such a problem. From time to time, while browsing the Internet, the screen of my laptop goes out, it happens for a few seconds, and sometimes I just have to carry it with the mouse and the screen turns on. When playing games or just working outside the browser, everything is ok. What to do?

Good day. Check which power plan you have set in the layout “Control Panel”. “Power supply”. Check the installed parameters in this section, since the problem lies precisely in them (if necessary, you can return the parameters preset in the system by default).

My screen turns on, “Windows Loading” appears and after that the message “No signal” appears on the screen and it goes out. How to fix? The cable is new. PC cleaned.

Hello. Reinstall the system on your computer.

Hello, there is such a problem. I have a fairly old computer (about 10 years old). During this time, 3 video cards and 2 more power supply units have accumulated at home. In general, the problem is that half a year ago, my monitor started to go out by itself, that is, I turn it on, and it turns on for a couple of seconds and the screen turns completely black. Without hesitation, I took a monitor from a friend for a test, put it on and it worked quite well. In general, a friend let him use his monitor, half a year passed and the same problem began on the friend’s monitor. I started digging into the components, put in another power supply, but still both screens went out, I decided to check the video cards further. I have 3 video cards at home and one integrated. I know about them that one of them is working, the second is already “dying” (in games it just hangs tightly, the service said that it can be used, but it will not work for games), the third one is also out of order, the image is there, but the whole screen in artifacts. In general, I initially installed a working one, there is just a black screen on the monitor, but I hear sounds, then I installed the 2nd video card, the same thing happened, there are sounds, and the monitor is black, but when I connected the 3rd card that is not working properly, the image appears. but with artifacts, but the very fact that it works, and the other two do not, then I also connected the monitor to the integrated video card, but there is no image either, but there are sounds. If the monitor is disconnected from the PC, then on the screen the inscription “connect the cable” and it does not flicker and does not disappear anywhere. In general, I have 2 questions
1. Why 3 out of 4 video cards do not work, although each of them should show at least an image
2. Because of what the screen can go out at once on 2 monitors?

Hello. Most likely both monitors are faulty. One of the video cards shows an image with artifacts for the reason that there is not such a heavy load on the monitor that others give.

Hello! Previously, when the computer was turned off, the image on the monitor disappeared along with a complete shutdown of the computer. Now, after one and a half to two seconds, while the shutdown process is in progress, the monitor screen goes out. Then it comes to life again. The computer starts booting without completing the shutdown. The computer can only be turned off the second or third time.
thanks for the answer.

Hello. In most cases, a conflicting software or virus affects a similar problem. If you installed any programs, drivers, or other software before the problem appeared, try uninstalling it. Also check your computer for viruses using your antivirus.

Alternatively, you can try to perform a system restore, rolling back the computer to the time when there were no problems with shutting it down. This can be done in the menu “Control Panel”. “Recovery”. “Start System Restore”.

Good evening! I have a problem like this. When the computer is running, the monitor screen goes out (black screen). Turned off the comr, then turned it on and during the startup process the system recovery window (win7) opened. After recovery, everything worked. What is the reason?

Hello. In your case, it is rather difficult to say what exactly influenced the occurrence of a detailed problem: it could be a virus, conflicting software, problems with Windows. If possible, reinstall the operating system.

Kait.15, good evening! Thanks, I thought so.

Why does the monitor go out??

It is impossible to answer this question unequivocally. There can be a lot of reasons, to figure it out sometimes you have to test all the components and you cannot do without the help of specially trained specialists. However, a few tips can still be given in this case.

The second reason

Monitor problems. There may be either the situation described above, or the backlight lamps could burn out (it will turn on, but after a while it gets dark). Perhaps it has overheating protection installed, then it will automatically turn off when the temperature rises, but the system unit will work.

Touch the monitor with your hand, if it is very hot, let it cool down and then turn it on again. The room in which he is located should not be very hot or humid.

To exclude a malfunction of the monitor, disconnect the cable with which it is connected to the system unit. The screen should display the message: “No signal”. “Check the connection cable” or something similar. If it does not appear, then it is worth contacting repair.


Also, a faulty video card may be the cause of the monitor fading or a sudden restart of the computer. You can read about how to replace it in the article “how to replace a video card”.

You can also just try to shake the video card in the connector, disconnect. connect the cable between the video card and the monitor, and reinstall the drivers on the video card.

Try connecting the system unit to another monitor or TV. If the image is displayed on the screen, then the video card is working.

It could also stop working due to banal overheating, for example, you launched a resource-intensive program or game. In this case, you can leave the side cover of the system unit open to provide additional cooling of the parts.

The monitor screen may remain black even if you connect it to a different video card. In some system units, there are two of them: one discrete, the second integrated (or built-in). In the BIOS, the one that is more powerful is selected by default (this is usually the first option). Accordingly, if you connect to the one that is not selected, the screen will be black. So, if you want to connect to a different video card, do not forget to change it in the BIOS.


Since we have touched on the inside of the system unit, then immediately pay attention to the amount of dust in it. If there is a lot of it, then everything needs to be cleaned. To do this, use a brush or a soft brush and vacuum cleaner. Brush off the dust with a brush, and immediately it is all sucked up by the vacuum cleaner, and does not scatter around the room.


View the cable. which it is connected to the system unit, for external damage. If you have a DVI cable, make sure that it is well twisted into the connectors on the monitor and system unit.

To be sure that the cable is working, find another one (for example, ask a friend) and connect the monitor using it. If everything works, buy a new one. If the problem persists, then it’s not the cable.

The first

If your monitor goes out when you are not working at the computer for a while (advice for complete beginners, and there are many of them), then this is all normal, it should be so. The monitor off time can be adjusted as follows:

Right click on the desktop and click Properties. In the window that opens, go to the “Screensaver” tab and press the “Power” button.

Opposite the item “Turn off the display” set the required time after which you want it to turn off.

Click on the “Start” button and select “Control Panel” in the list on the right

Show the view “Large icons” and click on the item “Power supply”.

Opposite the power plan, which is marked with a marker, click on the link “Setting up a power plan”.

In the window that opens, set the appropriate time to turn off the display from the drop-down lists: “Turn off the display”. and “Putting your computer to sleep.” Click the “Save Changes” button.

Right-click on the desktop anywhere in the empty space and select “Display Settings” from the list.

Then go to the Power & Sleep tab on the left and set the time after which the monitor turns off and the computer goes into sleep mode. If you click at the bottom on the link “Additional power options”. then the window shown in a couple of screenshots above will open.

If the monitor turns off during your active work at the computer. There may be several reasons for this. Personally, I had such a problem (I do not reprint this article, but write from personal experience) and it consisted in the fact that 15 minutes after the start of work, the monitor went out, especially if any game with more or less serious graphics was launched. So then the matrix on the monitor flew to me (the monitor is naturally W / C), it can be replaced naturally only in the service center.


The problem may also lie in the memory modules. If they are faulty or work with errors (this can be checked using standard Windows tools or third-party utilities), then the non-working RAM strips should be replaced with new ones.

In addition, the motherboard could fail. If so, then only replacing it with a new one will help.

The BIOS sounds can also indicate that there are problems in the computer. By clicking on the link, you can find out which signals correspond to which. For example, everyone’s familiar one long sound means that everything is in order and the computer is ready to start.

This describes the main reasons due to which the monitor may go out during operation, while the computer does not always turn off completely, the system unit may well work. If all of the above does not help, then I think it is better to contact the service center.
