Black Screen When Turning On Pc
Start the computer with one stick of RAM
In this case, you will NOT see a black screen with inscriptions when you turn on the computer. just a complete absence of an image. If you urgently need to start the machine, try to remove the damaged die and replace it with a new one.
To do this, remove the side wall of the system unit again and find the adjacent oblong strips: one, two, three, and so on. If there is more than one of them, alternately, Do not forget to turn off the PC every time, Remove each and check if the image appears on a new start.
At the same time, we recommend that you remember the location of each bar: this will allow you to avoid inconsistencies with the memory selected by a professional. We gave some tips for installing RAM in the article at the link. Found a problematic plate? Great, now try to put any worker in its place. As a result, the computer should boot normally. then the problem is definitely in memory. If there are images on the screen again, the problem is most likely in the connector itself.
While checking, do not be too lazy to clean the dies from dust: this will prevent the appearance of a blue screen. Have you decided to buy a new memory? Check out the parameters of the memory that has fallen into disrepair. and purchase exactly the same one. You can entrust this matter to a specialist. he will cope with the selection faster and more competently than a simple user.
Try to restore Windows in “Safe Mode
Now that we’re done with the hardware, here are some tips for software. First of all, you need to try to perform a system restore, sequentially accessing the “Explorer” and rolling back to the last work point. An indispensable condition is the creation of backups activated in the OS: if they are not there, you will NOT be able to use the instructions below.
To get down to business, use the aLGorithm:
- Start the machine and when a window appears on the monitor asking you to choose a boot method, select “Safe Mode”. If such a window has comments, call it on your own, immediately after starting by pressing the F8 key. The manipulations described below will work only if something is displayed on the display. a black screen and a cursor appear when the computer is turned on.
- Next, in order not to take too drastic steps, select the last working configuration for loading. If a full image appears on the display after that, congratulations: you solved the problem.
- Unfortunately, with a very high degree of probability, you will NOT cope with the problem so easily. All is not lost: when you turn it on again, select the already safe mode. then its configuration that supports working with the command line.
- In the window that appears, enter and apply, using the Enter key, the first command: explorer.exe.
- In a few seconds you will be able to access the standard Windows Explorer. It’s too early to rejoice: after a new cycle of switching off-switching on, the malfunction will return to its place. To completely eliminate it, we will take the following measures. To get started, open “Start” and go to the sub-tab “All Programs”.
- Here click to mark the folder “Standard”.
- Next. Refer to the “System” subfolders.
- Here you will find a shortcut to proceed to System Restore. Click on the entry of the same name with the left mouse button.
- To start the process, click on the “Next” button.
- In a new window, in order to cope with the problem causing a black screen when starting the computer, mark to which of the saved points you would like to roll back. It is not worth choosing too old versions; usually it is enough to select the last save to normalize the work. Can’t find a suitable option? Then check the box “Show others”: perhaps the best point for you is hidden here. After clicking the mouse on the appropriate option, click again “Further”.
- Carefully read the warning of the system in possible difficulties. and, since there is still a second way, click “Finish”.
- To finally confirm your intentions, click “Yes”. and leave the computer alone for a few minutes.
The machine will reboot during operation. When the restore is complete, you will have full access to your desktop. To make sure the monitor is working as expected, restart your PC again and see the result.
Tips for identifying software black screen problem. Check the map
The second point that you definitely need to pay attention to is the adapter. To make sure that it is in physical condition, turn off the PC and, carefully removing the side wall of the system unit, disconnect the card from the motherboard. Now remove it, being careful NOT to touch the contacts or surrounding equipment. We strongly advise that you do not contaminate the device by wearing medical gloves.
Using a paintbrush, clean the surface of the card from dust and small solid particles. very often it is because of them that the computer does NOT boot, when you turn on the black screen.
Using a cotton swab dipped in an alcohol solution, wipe, rather than exerting unnecessary effort, the contacts of both the card itself and the motherboard. Metal parts Must be free of streaks, greenish spots and dirt. It is not recommended to erase dirt with an eraser: the spools may remain in the contacts, which deteriorates the connection quality.
At the end of the process, reconnect the device, trace so that the connectors are connected as tightly as possible. Turn on your computer and see if the situation improves.
The second way out of the situation is to use the built-in graphics adapter. with a high degree of probability, in addition to the external card, your motherboard also has a built-in one. Yes, it is less powerful and is unlikely to allow you to play your favorite games, but it is capable of providing an image on the screen. at least until you purchase a new card. To switch to embedded resources, simply connect the cable to the Corresponding connector; it is best to do this with the computer turned off. After turning on, the familiar welcome screen should appear on the monitor. and you can get to work.
Among other things, sometimes after turning on the computer, a black screen appears due to a conflict between a third-party and an embedded card. In this case, since it is dangerous to physically remove the “wired” equipment, it remains to disable it using BIOS commands. You can solve the problem both independently and by contacting a specialist.
Remember: before removing the plug-in card, be sure to turn off your computer and wait until the processes have completely stopped. To ensure the safety of the equipment, you can additionally use the toggle switch on the back wall, set it to the “off” position, or simply unplug the plug from the socket. When finished. do not forget to make sure that the card is inserted correctly, firmly seated in the slot. If the device is secured with a screw, tighten it within a reasonable limit, and not using excessive force. Try not to pick up the adapter and DO NOT touch the contacts with bare hands: grease transferred to conductive elements will negatively affect performance.
Hard reset the BIOS of your computer (be sure to try)
To take advantage of this simple, albeit complicated looking way, allowing you to understand what to do if the computer does not start, a black screen, strictly Follow the instructions:
- Turn off the PC using the “Start” button, and then completely cut off the current flow. You can move the toggle switch on the back of the power supply to the desired position or remove the plug from the outlet.
- After removing the wall of the system unit, inspect it from the inside. Remove accumulations of dust, dirt, foreign objects inside. It is best to operate with gloves, using a soft brush for painting or makeup. Be especially careful to clean the area around the circular battery located on the motherboard. in the center or closer to one of the edges.
- Sometimes, to get to the battery, you have to disconnect the PC components from the power supply. In this case, remember the location of the entrances. then, when reassembling, one riddle will become less.
- Carefully, using a thin sharp object to pry off, remove the battery from the slot. Before removing, remember which pole of the power supply was facing out.
- Among other things, a flat screwdriver or tweezers can be used to make the work easier. If the battery is secured with a latch, no additional tools are required.
As a result, you can reset the CMOS module responsible for the BIOS memory. Sometimes zeroing takes a few moments. just remove the battery and then reinstall it. Most often, however, it takes significantly longer to completely de-energize to reset the memory. To speed up the procedure, press the power button on the system unit (not connecting the PC to the network) or use a screwdriver to connect the contacts in the battery connector. When finished, plug the power supply back in, and after assembling the computer, start it up.
This is another answer to the question of what to do if there is a black screen on the computer. Finding the battery is extremely simple: it is a shiny metal circle located on the outer side of the motherboard facing you. The PC uses only flat power sources of a relatively large diameter. the latter factor greatly simplifies removal and new installation.
Make sure that the computer is completely turned off and de-energized before starting work. In some cases, removing the battery, rather than breaking the integrity of the motherboard, will not work; this is especially true for laptops and monoblocks. We described how to reset the BIOS on a laptop in this article.
Make sure the card driver is working
Service utilities used to process information supplied to peripheral devices, including the display, must be constantly in good condition. Damage to one or more modules can lead to the described problem. which means you need to try to restore the drivers.
To make sure that the utilities are in full working order, follow the instructions:
- After turning off the PC, start it again and, as described in the previous section, enter “Safe Mode”. In this case, it will be optimal to choose the option with the lowest screen resolution.
- A picture should now appear on the monitor. Once in the Start menu, open the Control Panel.
- From here go to “Device Manager”. In new generations of OS, you can, to find the Corresponding tool, just click on “Start” with the right mouse button.
- After waiting for a new window to appear, expand the “adapters” subdirectory.
- Since when the computer boots, a black screen appears, as we assume in this section, due to the incorrect operation of the graphics adapter driver, find your card in the list and, by opening the corresponding sub-tab in the “Properties”, remove the current software.
- After restarting. it must be done without fail. independently install the drivers supplied on the disc by the manufacturer, or download the latest version for your adapter model on your PC.
- If you can’t remember the name of the utility, use a combination of Windows and R.
- In a text line, enter and apply the dxdiag query.
In a new window called DirectX, you can find the name and model of your card. by these parameters, you should look for a suitable driver.
Why a black screen and the computer won’t turn on: what to do if when you turn on the PC, it won’t start
“Hello, help who can)! I have such a problem: Comp. went into standby mode and does NOT come to life (black screen), keyboard and mouse (USB) do not work, it turns off only when you press the power button on the back panel. When the computer is turned on, it boots, but still a black screen, the mouse and keyboard do not work (there are indications) after 30 seconds of loading, it will cut itself off after 2 seconds and will turn on itself and so three times (even funny). The third time, at the end, it loads completely, but as always, the black screen (the worker checked the monitor) inserted a mouse (PS2) does not work, but there is an indication. I think that oregano (Socket 1156 Asus P7H55) is only one year old, only with a guarantee flew off)))))) “
No matter how stable and modern the operating system you use, one day you may, instead of the usual desktop, face a problem: the computer does not work. The black screen and fan are running and the computer will NOT start. Most likely, the first feeling that you will experience will be sincere bewilderment: what went wrong since yesterday and what needs to be done to normalize the situation?
First of all, let us note that if the fans are running, it is not entirely correct to speak of “not starting” the NK. The problem can be both hardware and software. but the rest of the components are likely to continue to work normally. Sometimes you can even see the mouse pointer on a black background. in which case it is almost certainly the operating system.
DO NOT despair and immediately take the equipment to the service center. First of all. Explore the Tips We Offer and try them all, moving from easy to difficult. DO NOT stop at the first try: it is quite possible that you will succeed at the second or third time. Only then, if all else fails, contact a specialist. otherwise you risk wasting money. By the way, if you do not have a stationary computer, but a laptop, then we advise you to read both this article and the article about a black screen on a laptop.
Tips for identifying a black screen hardware problem. Check your system for viruses in Safe Mode
It is impossible to exclude the adverse effects of viruses brought on the PC due to careless downloading of files, installation of programs and games, connection of unfamiliar flash drives.
To fix the problem, boot to Safe Mode again, and then Scan your files and registry entries. Ruthlessly delete any potentially dangerous data you find. You can use any product as a verification tool, including rescue discs.
Black screen when turning on computer
In this article I want to share with you my observations of the situation when we observe a black screen when the computer is turned on. When the computer is turned on, this black screen in the department we call. “Malevich painting” 🙂
Again, I will make a reservation that we have already analyzed in detail all the main points and breakdowns associated with a black screen when the computer boots up in the section of our website, which is called “Repair your computer yourself”. We had separate articles related to hard disk problems, an article dealing with RAM problems, an article called “burned out motherboard”, “how to reset BIOS settings” and a lot of other useful information on the topic of self-repairing a computer.
Be sure to read them for a full understanding of what the main malfunctions of computer equipment are, how they should be correctly diagnosed and eliminated. Also, pay attention to the article in computer power supplies (the last few paragraphs of it), which talks about insufficient power of old power supplies, which can lead to a black screen when you turn on the computer.
Below I want to share with you one more observation, why you can see a black screen when you start your computer? Both cases I had were connected with computers that were brought to me for repair (I still follow my home better) 🙂
In general, when diagnosing someone else’s computer, keep the following in your head: I don’t know how this or that owner treats the equipment (what is the norm for some, may be completely unacceptable for the second). For example, I had a case when the hostess of the house decorated her system unit with souvenir fridge magnets! Can you imagine what happened to the poor car ?! 🙂
So. let’s continue. I will describe two of my non-standard cases, when the computer was turned on with a black screen. In both cases, the reason was the same. adhesion of foreign matter (simply. dirt) on the track of the printed circuit board. Only in the first case it was the motherboard, and in the other. discrete card. The result, as you can see, is the same. black screen when turning on computer.
According to one “informal” definitions: “mud. This is any chemical compound that is not in place.” 🙂 I don’t know what connections the dirt on the motherboard consisted of, but after removing it with an alcohol solution, the computer started up normally and works to this day.
The second case, which led to the appearance of a black screen when the computer was booted, I even managed to photograph for you. Once we bought 10 old PCI cards for terminal clients on the radio market for a department of pieces. They brought it, started testing (substitute one at a time in the pre-assembled working configuration). Seven cards turned out to be working, three. no. I twirled the last of the non-working in my hands, mentally wondering at the sellers who sell faulty devices, and noticed a strange darkening in the corner.
Let’s enlarge the part of the image of interest to us for clarity:
You can clearly see the adhering dirt on the PCB tracks. Remembering my previous successful experience with cleaning, I decided to carry out the same procedure and find out if this particular substance causes a black screen when the computer is turned on.?
Said. done! Was at hand “Mister Muscle”, took it, moistened a lint-free cloth and carefully removed all the dirt from the tracks. Here’s what I ended up with:
He let the card dry, inserted it into the computer, turned it on and. it all worked! 🙂 Now it works successfully on one of our terminal clients.
Conclusion: if you see a black screen when you turn on your computer (especially if this is not your computer), do not be lazy to make sure that it is the owner. adequate people and DO NOT fill their technique with sweet syrup (there was such a case) and handle it carefully.
How do I repair my computer myself? Let’s answer like this: attentiveness, attentiveness, and again. attentiveness! Here is the advice that will help you avoid losing your time and nerves if the computer does not work and you need to professionally diagnose its malfunction.
OS recovery from under “safe mode”
The first method involves using a “command line” running in “safe mode” to activate the explorer.exe application and then roll back the OS to a healthy state. This method can be used when the device has a restore point formed in the appearance of a problem with a black screen.
- First of all, you need to go to “Safe Mode”. To do this, restart the computer and when you turn it on again after the beep, press the F8 button.
But most of the time it doesn’t help. Then, in the boot type shell, select the option that involves activating “safe mode” with “command line” support. Then press Enter.
The system will start, but only the “Command Prompt” window will open. Type into it:
After typing press Enter.
Open the “Standard” folder.
Enter the directory “Service”.
In the opened list of tools select “System Restore”.
The starting shell of the standard OS resuscitation tool is activated, where you should be named “Next”.
Then a window is launched where you should select the point to which the rollback will be performed. We recommend using the latest version, but which one was necessarily created even before the error with a black screen appeared. To expand your choices, check the box “Show others.”. After highlighting the name of the optimal point, click “Next”.
In the next window you only need to click “Finish”.
A dialog box will open where you should confirm your intentions, clicked “Yes”.
Solve black screen problem when turning on Windows 7 computer
Sometimes, when booting the system, users encounter such an unpleasant problem as the appearance of a black screen on which only the mouse cursor is displayed. Thus, it is simply impossible to work with a PC. Consider what are the most effective ways to fix this problem in Windows 7.

Troubleshoot a black screen
Most often, a black screen appears after the Windows welcome window has been opened. In the vast majority of cases, this problem is caused by an incorrectly installed Windows update, when some kind of failure occurred during the installation. This entails the inability to start the system application explorer.exe (“Windows Explorer”), which is responsible for displaying the graphical shell of the OS. Therefore, instead of a picture, you just see a black screen. But in some cases, the problem can be caused by other reasons:
- Damage to system files;
- Conflict with installed applications or drivers;
- hardware faults.
We will explore options for resolving the indicated problem.
Recovering OS files
But there are times when the OS files are so badly damaged that the system will not boot even in “safe mode”. It is also impossible to exclude such an option that you may simply not have the necessary restore point on your PC. Then a more complex procedure should be performed to reanimate the computer.
- When starting the PC, move to the window for selecting the type of download, as demonstrated in the previous method. But this time from the presented items select “Troubleshoot.” and press Enter.
The recovery environment window opens. Select “Command Line” from the list of tools.
The “command line” interface opens. In it, Let’s enter the following expression:
Be sure to press Enter.
The “Registry Editor” shell will start. But you need to remember that its partitions will NOT belong to the Active OS, but to the recovery environment. Therefore, you need to additionally connect the Windows 7 registry hive that you want to fix. To do this, in the “Editor” select the section “HKEY_LOCAL_MACHINE”.
Then click “File”. In the list that opens, select “Load bush.”.
The bush loading window opens. Go to the partition of the disk where your operating system is located. Then go sequentially to the directories “Windows”, “System32” and “Config”. If, for example, your OS is located on drive C, then the full path for the transition should be as follows:
In the opened directory select the file called “SYSTEM” and click “Open”.
The “Loading partition hive” window opens. Enter in its only field any arbitrary name in Latin or using numbers. Next click “OK”.
After that, a new section will be created in the “HKEY_LOCAL_MACHINE” folder. Now you need to open it.
Select the “Setup” folder in the opened directory. In the right part of the window, among the elements that appear, find the “CmdLine” parameter and click on it.
In the window that opens, enter in the field the value “cmd.exe” without quotes, and then click “OK”.
Now go to the properties window of the “SetupType” parameter by clicking on the Corresponding item.
In the window that opens, replace the current value in the field with “2” without quotes and click “OK”.
After that, go back to the “Registry Editor” window to the section that you connected earlier and select it.
Click “File” and from the drop-down list select “Unload bush.”.
A dialog box will open, where you want to confirm the decision, clicked “Yes”.
Then close the “Registry Editor” and “Command Prompt” window, thus returning to the main menu of the recovery environment. Click here on the “Restart” button.
After restarting the PC, the “Command Prompt” will automatically open. Type in the command there:
Press Enter here.
The computer will be checked for the integrity of the file structure. If violations are found, the procedure for restoring the corresponding element is automatically activated.
Lesson: Scanning Windows 7 Files for Integrity
After the restore is complete, enter the following command:
If none of the above methods helped, then in this case you can install Windows 7 on the floor of the working operating system with all the settings saved, or you can completely reinstall the OS. If these actions did not work, there is a high probability that one of the hardware components of the computer is out of order, for example, a hard drive. In this case, it is necessary to repair or replace the broken device.
The main reason for the appearance of a black screen when booting the system in Windows 7 is an incorrectly installed update. This problem is “cured” by rolling back the OS to a previously created point or by performing a file recovery procedure. drastic actions also involve reinstalling the system or replacing hardware elements of the computer.

The screen is also black as soon as the command line is loaded. Doesn’t enter any mode at all
After editing the registry and rebooting on the screen “The installation program prepares the computer for the first use” and then nothing happens.
Hello! I have this text. In the attached file. What does that mean? thanks in advance.
Hello, most likely, you cannot boot from your hard drive. Perhaps the BIOS settings are out of order or you yourself changed them. To fix this, you need to set your hard disk bootable in the BIOS, and how to do this is described in the following article: How to make a hard disk bootable. If this does not help, you need to check the physical connection: power off the PC, open the lid of the system unit and check all the cables going from the hard drive to the motherboard and to the power supply. You can reconnect the HDD to a different SATA connector on the motherboard or use a different SATA cable altogether, if you have one.
Thank you Anastasia Viktorovna! It was about the cable.
When Windows boots up, the cursor blinks at the top left on a black background. That’s it. A lot of Acronis backups. Recovery is successful. At boot, too. I don’t know what to do. Help please
Comp. I have NOT used it for over a year. Now I have turned it on DO NOT wake up whatever I do! Elena.
Good afternoon. There is very little information to give you advice. Describe what exactly happens when you try to start your computer. If the computer does NOT react at all to the attempt to start it (even the fans do not turn on), then the following options are possible:
1). The toggle switch on the back of the system unit is not included. In this case, just turn it on.
2). The cable plugs are poorly connected or the power cable has broken at all. Check if the plug is firmly connected to the system unit. If possible, try connecting a different power cable to see if this is not the problem.
3). You have a broken power supply inside the system unit. In this case, there is only one option. to contact a specialist.
4). Also if you are connecting your computer via an uninterruptible power supply (UPS). then there may be problems with him. to eliminate this possibility, simply connect the system unit directly to the network, bypassing UPS.
These are the main reasons, but there may be others.
Again, it is difficult to give you some advice rather than knowing the details.
This message appears
Good afternoon. This means that the computer cannot find the operating system. The reasons can be many from damage to the boot record to physical damage to the hard drive. First, try to restore the boot record as described in this article:
Repairing the bootloader in Windows 7
The term did not start
Good afternoon. Describe in more detail at what stage do you have problems starting the “command line”? The boot type selection list does not open, the recovery environment window does not open, or the problem occurs after that. how you clicked on “Command Prompt” in the recovery environment?
If the boot type selection list is NOT available at all, then try to boot from the installation disk or flash drive and in this way call the recovery environment and the “Command line”.
This solution helped me:
Open the main menu “AVZ” (you can use the “portable” version of this free antivirus program, which runs from a flash drive)
Will be named “System Restore”;
Put the checkboxes in the columns “Explorer recovery” and “Workstation recovery”;
Click on “Perform Selected Operations “;
When turning off and on the laptop, I pressed f8 and nothing worked. And in general, after switching on, the company logo appears, then a black screen and a dash blinked in the upper left corner. After a long time, I was downloading files and starting to load Windows on a black screen, then the mouse cursor appeared on a black screen. The laptop does NOT respond to any key combinations.
At boot, when you press F8, comments on the item “Troubleshooting computer problems”, you need a different way.
Hello, I need your help. It all started with blocking the D drive in Bitlocker. After encryption, my netbook was loading Windows for a very long time and then it did NOT boot at all. I tried safe mode and turned off the bitlocker there, but still the problem was not solved. Then I decided to just reinstall Windows to update everything, downloaded the UltraISO program, downloaded the Windows 7 maximum image and made a bootable USB flash drive. Everything was fine, the reinstallation began, but the process was very long (it couldn’t take more than a day) and at the end it gave “The computer has unexpectedly restarted, or an unexpected error has occurred. It is impossible to continue installing Windows “after that I tried to solve the problem with the shift10 command line, the regedit window opened, everything was true, everything was a little different, but still at the end it was necessary to restart the computer with the shutdown.rt command 0 after that the computer booted but a black screen appeared and hung after I thought to solve it with safe boot, but after I pressed f8, when I turned it on, a window with a choice of boot should have opened, but instead I don’t remember exactly, but there were only 2 options for loading Windows and rolling back Windows and I didn’t even have time to press something as he went to load himself everything, but again for so long, and an inscription came out that the program prepares the computer for the first boot, now after a long boot, I asked to activate Windows, I pressed do it later, but the computer again with a black screen in the lower right corner of Windows 7, etc. what to do?
Hello, after the windows 10 greeting, a black screen glows, the monitor button works, what is the problem please tell me
Help me please. I downloaded the new windows 10. I started downloading the browser and after 2 minutes a black screen appeared, it glows a little black, the monitor button works and the menu too, why did I reinstall windows, but the same problem was

Black screen on computer startup. Windows Media not licensed.
For most users, it is a surprise that a black screen appears on the desktop after updating the operating system. This happens to users of a pirated, jailbroken version of Windows. In this case, in the lower right corner, near the clock, you will see the inscription: “Your system is not genuine, after purchasing a license”.
If you are faced with this problem, then you have two solutions:
- Reinstall the system, and after reinstalling, disable the installation of all updates, but then you risk that your computer may be infected with a virus, for example, such as Wanna Cry;
- Buy a license for your product and sleep well. After all, the computer will receive all the necessary patches and work more stably.
Unfortunately, there is no second way out of this situation.
Windows boot problems
Probably the most common reason for a black screen is a failure to boot the operating system. Very often it occurs when the system is shut down improperly or the boot area is damaged.
In most cases, this problem occurs when users unexpectedly turn off the power and the computer turns out to be de-energized at the most inopportune moment.
With this outcome, the user will see a black screen when the computer is turned on with the system boot options.
Here, most often, it is enough to select the item “Normal boot Windows” and wait for the system to start.
If the system does not give you a window with boot options, then you need to do the following:
- After you have turned on the computer, you must press the “F8” key, the “Additional boot options” window should appear;
- In this window, you can select three options “Safe Mode”. With it, you can boot the system and fix the problem that arose after an unexpected shutdown of the PC, Incorrect installation of software or viruses;
- If you are sure that everything is fine with the computer, then select “Normal Boot”
Windows desktop does NOT load.
Another fairly common prerequisite in which the user sees a black screen when the computer is turned on is a non-loading desktop. The problem arises after cleaning the computer from viruses. At the same time, the system seems to be loading, but the desktop remains empty: no shortcuts, no folders, no taskbar. If you have a similar situation, then do the following:
- First of all, we launch the Windows Task Manager, for this we press the hotkey combination “Ctrl” “Shift” “Esc”;
- In the task manager window that opens, click on the “File” menu and select “Run a new task” in the list that appears;
- Next, in the window, enter the “regedit” command to launch the registry editor;
- The “Windows Registry Editor” window will load, in it we navigate along the path:
HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CurrentVersion / Winlogon
- In the “Winlogon” branch we are looking for a key “Shell”, this key must have the value “explorer.exe”. If you see a different value or an empty field altogether, then write the correct parameter and save the settings;
- After the performed manipulations, we restart the computer and are glad that everything works as before.
Defective system unit components.
If the above tips did not help fix the problem, then most likely there is a problem with one of the components of the system unit.
To begin with, you should open the cover of the system unit and inspect the computer components, it is possible to clean them from dust and dirt.
Also, inspect the motherboard for swollen capacitors, perhaps the reason for all the troubles is in them. Then, most likely, you will need to replace the node, namely the motherboard or solder faulty elements.
Remove the card from the system unit and clean all contacts. Possibly oxidation or dust ingress over time.
Next, we check the connection of all wires, if the card requires additional power, then it must be connected.
RAM can also be a prerequisite for a black screen and system failure to boot. If there are several memory modules, then we take out everything and try to connect one at a time and test the computer startup. If the system starts successfully, we conclude that some memory bar is not working correctly, and we change it to another.
Also, be sure to clean the contacts of all memory modules, perhaps the reason is quite banal, there is no contact between the motherboard port and the RAM module.
Black screen when turning on the computer. what to do?
Hello! If you see a black screen when you turn on your computer, then this is the first sign that some kind of problem has happened in its work, which DOES NOT allow the Windows operating system to function normally. There may be several reasons for this phenomenon, we list them:
- Improper shutdown of Windows;
- The computer does not see the hard drive;
- Damage to the monitor interface cable or lack of contact;
- NOT loading desktop;
- Missing Windows license;
- The components of the system unit do not work;
- Software problems, viruses, lack of drivers;
As you can see, there are a lot of reasons when a black screen appears when you turn on the computer, so we will analyze each of them separately and try to fix the problems ourselves.
- Windows boot problems
- Cable or monitor problems.

Since many modern PCs are equipped with a discrete and integrated graphics adapter, you can simply connect the monitor to the integrated adapter and check if the image appears on the screen.
Overheating is a common cause of failure of discrete adapters. By the way, if you are not aware of which adapter you have installed, then read the article. How to find out the map of your computer.
Less commonly, the image on the screen refuses to appear due to incorrectly installed drivers. To eliminate this problem, download the latest driver for your card from the official website and install. Perhaps the problem will be solved by itself.

If the indicator is on, then the monitor is powered, if not, then we look at the power wires. Perhaps they are not connected to the network or some contact has moved away.
