Bios Does Not Start On The Computer Black Screen

BIOS does not load: instructions for solving the problem

BIOS is the Basic Input / Output System, the heart of the computer, without which the normal operation of the second components and software is impossible. When you turn on the computer, the BIOS starts up first and only after turning it on, the operating system starts loading.

In theory, since Windows boots after the BIOS, reinstalling the operating system or adding another OS should NOT affect normal BIOS operation. However, it is not uncommon for an attempt to install a second operating system to result in the BIOS NOT loading.

In this case, we can assume that the BIOS settings are out of order and restoring the default settings can solve the problem. To reset the settings, you need to carry out the following operations.

  • Disconnect PC and monitor from mains.
  • Open the system unit and remove the battery from the motherboard.
  • Wait a few minutes.
  • Replace the system battery.
  • Connect power to computer and monitor.

After restarting the BIOS will start to boot “like the first time”. If the problem disappears after doing this, it is recommended that you format the bootable hard drive and reinstall the operating system. It is desirable that one that previously worked without problems. It is possible that the added operating system turned out to be damaged in the distribution.

Connection violations

It is highly likely that the BIOS does NOT boot due to breaks in the power supply network or data loops. To check this option, you first need to listen. is the cooler spinning on the motherboard. BIOS is part of the processor and therefore poor cooling of the motherboard leads to malfunctions.

Perhaps the contact groups of the fan have moved away, so it does not work. Then carefully inspect all cable and loop connections. Check for dust accumulated on the motherboard or in the contacts. Dust is an excellent conductor of electric current, and even creates electrostatic fields, to which electronics are very sensitive.

  • Clean the device from dust with a vacuum cleaner and a brush.
  • Disconnecting contactors in sequence and clean the terminals from dirt and oxidized. You can use a school rubber band to clean the contacts.
  • Check that all connectors are secure. It is likely that the vibration caused the contacts to disperse, and therefore the equipment stopped working correctly.

After preventive maintenance, you can try to restart the computer. Is the screen black again and the BIOS is NOT loading? Then it can be assumed that one of the internal modules is faulty. Including the motherboard itself could fail or it needs to be reflashed.

You can download the new firmware for the motherboard on the manufacturer’s official website. Updating the firmware is a difficult and rather risky task. Therefore, if you do not know exactly what and how to do it, it is better not to risk it, otherwise the whole computer may be ruined, in a place with hard disks. Better contact the service center.

Faulty blocks in the computer

None of the above helped? Then the probability of hardware malfunction increases and you can start checking blocks.
Unplug and unplug anything not required to start the computer from the device. Leave only the motherboard, power supply, and one of the RAM sticks. The computer will NOT work in this state, but it is possible to check the health of the motherboard itself.
A frequent prerequisite for the inability to start a computer is insufficient power supply unit. For example. you replaced the motherboard with a more advanced one that requires more electricity. At the same time, the power supply remains old. Or so. additional hard drives or some other functional components were installed in the system unit. Energy consumption can rise quite dramatically. Installing a more powerful PSU will solve the problem. If the question is, of course, the lack of energy.

Often a card malfunction interferes with BIOS loading. If possible, you need to check the card by replacing it with another Similar one. Or install the card in another computer. Here you need to look at the compatibility of the equipment. Otherwise, you will not find the problem, but you can create new faults.

If in the minimum configuration. a motherboard, a power supply unit, a RAM socket. the system unit is working and the BIOS is loaded, then the problem is in one of the removed modules. After installing and connecting the next unit, try turning on the computer again and see what happens. As soon as the BIOS stops starting again, it can be assumed that you have found a faulty block. Now all that remains is to find a similar one and replace.

In reality, everything is often much more complicated. For example, the computer sometimes boots up and works quite normally, and then, for no apparent reason, starts to glitch. The problem can be either a software malfunction or a component malfunction.

These periods of normal operation, alternating with failure to boot the BIOS, are common for three types of problems.

  • Microcracks on the motherboard. Because of this, contact periodically disappears.
  • Dried electrolytic capacitors on the motherboard or power supply. This malfunction mainly applies to old system units that have been in operation for a long time. Sometimes faulty capacitors can be identified by the characteristic swelling of the case.

Poor contact in connected wires. As already mentioned. the presence of dust, oxidation of contacts, insufficient pressure. If the contactors have fixing screws, they must be tightened to the end. The opposite situation also happens. too tightly clamped locking screws lead to deformation of the connectors and disruption of contact in the connection.

The computer turns on, but the monitor screen is “captured by black secrets

As a rule, problems with starting a computer system are always accompanied by a specific sound signal, the tonality and sound sequence of which has its own decryption code.

To solve the described problem, you can also try to change the computer’s power supply, but to a greater degree, this “PC behavior” indicates that the BIOS has detected a faulty component in the system: one of the memory sticks (RAM) is out of order, the hard drive is broken, or the processor temperature has reached a critical level. In the latter case, it is necessary to replace the thermal paste and check the cooling system cooler for serviceability.

The rest of the user’s actions should be as follows:

  • Disconnect all peripheral devices (printer, fax, webcam, external storage devices, etc.).
  • Remove all RAM modules.
  • Disconnect hard drives.
  • Switch to another graphics mode. change the circuit from an integrated to a discrete one or switch to an integrated chip if you used an external card.

If the empty mainland starts up, throw one at a time from the previously disconnected components and carefully monitor the reaction of the microsystem as a whole. In any case, if the BIOS starts up, then you have already achieved a positive result.!

By the way, do not forget that a black screen can be the result of a failed monitor. In laptops, the integrity of the connecting cable is often violated, which is constantly subjected to dynamic load when opening / closing the display cover. In the latter case, it is better to contact a laptop repair service center. Both in the first and in the second case, to check the truth of the assumption, you can always try to connect an external monitor to the VGA connector.

Situations:. black screen

The first and most unpleasant situation is that you press the power button on your computer or laptop, but the computer does NOT boot, the BIOS does NOT load, and you see a black screen in front of you. You wait further, but in vain, because nothing else happens. In this case, to determine the reason why the computer or laptop does not boot, you need to listen to the sounds that the BIOS produces during boot. One short beep usually means that the BIOS has successfully completed a hardware check.

BIOS does NOT start: what to do and how to “revive” the microsystem

The basic I / O system is the beginning of the electronic life of a computer. In the event of a hardware or software malfunction, the BIOS microchip. the safe start of the computing device simply becomes NOT possible. Do not look at the extreme degree of reliability of the specified element of the computer system, software failures in the basic microsystem (in view of many factors!) Still take place. In most cases, the problem “BIOS does not start: what to do?” allowed by an elementary replacement of the CMOS battery, otherwise it is required to apply a comprehensive diagnostic plan, and only after identifying the cause of the problem, make a repair (correct!) aLGorithm of actions. details in the article!

Reasons why BIOS does NOT start

Imagine this situation: one fine day you turn on your computer or laptop and see that It does not start; furthermore, you find that the BIOS is NOT loading. Surely those of the readers who have come across a situation when a computer or laptop does not boot or even does not start, hardly found it pleasant. In addition, it may happen that the computer or laptop itself turns on and loads the BIOS and operating system, but you cannot enter the BIOS, that is, the BIOS Setup program does NOT start. In this article, we will try to give advice on what to do when the computer or laptop turns on but does not load the BIOS, and the system does not boot beyond the hardware check procedure and the operating system does not start or BIOS Setup does not load, and how you can solve these problems.

At the end

Here, in brief, is the entire list of instructions on the problem “BIOS does not start: what to do”. We hope everything worked out for you and access to the basic settings is restored. Of course, do not lose sight of another not described way of fixing the problem of auto products. switch the CMOS jumper to the RESET position (then return the contact element to its original position).

You know, this article is a great continuation, because the BIOS may NOT start due to swollen capacitors, as well as “dead” transistors. Do not miss!

Black screen and no beeps

If the computer turns on, but the “black screen” is NOT accompanied by any beeps, then it can be assumed that something is wrong with the power system. For example, the power supply has failed and for this reason does not supply the required voltage to the system board. Or there is simply no contact between the motherboard and the power cable. Also, a prerequisite for the problem may be a malfunction of the BIOS itself, the motherboard, the processor, memory, and even the hard drive. In addition, sometimes a prerequisite for the computer NOT to boot may be insufficient cooling of the electronic components of the motherboard.

Black screen and multiple signals

The presence of several signals at the moment when the computer is turned on and the system boots, usually means some kind of malfunction. As a rule, the meaning of THESE signals is different for different BIOS models. But most likely, if you do not have all the views on the screen, then the problem is again related to the system, but this time, most likely, with the map. However, in order to be completely sure of this issue, it is best to refer to the list of conditional beeps for the BIOS version that is installed on your computer or laptop.

This “electronic opportunity” has a rather long list of “causes and effects”, nevertheless, it is possible to single out the main symptoms of a malfunction, namely, to identify in the shortest possible time the real culprit of the “silent celebration”.

  • With a probability of 99.9%, the power supply has failed. Naturally, replacing components with a known working power supply unit will correct the situation towards “Problem resolved”.
  • The power button is out of order. replacing the switching element or checking the wire for mechanical damage (obvious breakage, deformation of the wire, oxidation of contacts, etc.), of course, with its subsequent restoration (soldering, cleaning).
  • Dust contamination of the inside of the computer case (especially important for portable computer equipment. laptop). it is necessary to remove dust from all components of the motherboard, as well as the supplied modules and strapping equipment. Do not forget to clean the air intake grilles and other structural elements of the enclosure.

How to enter basic computer settings

Depending on the BIOS version (s), as well as the design features of the computer, access to the basic settings may radically differ from the methods that are considered standard.

For example, in most PC modifications, the BIOS is entered by pressing the “F2” or “Delete” function button. over, activation of one of these buttons is carried out directly at the moment of starting the computer system at its initial stage. By the way, there is a special technique for calling the main BIOS menu. repeatedly pressing the corresponding button with an interval of two clicks per second.

There are other “tactile schemes” for entering the BIOS. some manufacturers supply their devices with special mechanisms, push-button or lever-type, when activated, the user enters the service menu of the basic microsystem. However, there are also more exotic buttons. touch. However, the essence of the listed keys and service gadgets is the same. calling the BIOS Setup menu.

As for the “high-speed resistance” of the moment of entering the basic menu of computer settings, there are several solutions:

  • Enter the BIOS menu via Windows OS. use this link to read how it is done.
  • Try calling BIOS using the second service keys, for example, “F8”.
  • Finally, you can get into the basic settings using the rescue disk “System Restore” or a distribution kit with Windows.

NOT a quick introduction: small BIOS and big consequences.

Indeed, here is a small microcircuit, which contains a set of microprograms in its memory, and in the aggregate is the basic microsystem of a computer, everything depends! Found, in our time, very rare, electronic ailments. damage to the main BIOS entry of the system (not to be confused with the temporary data stored in CMOS memory!). This is a “dead” motherboard. That is, the motherboard becomes completely useless, since only on the controlling element of the launch.

Partial BIOS microchip failure can be accompanied by an incredible number of surprises, both hardware and software. In general, the beginning of all computing beginnings is a small microcircuit with a certain set of programs. How correctly you set up the BIOS depends on the degree of efficiency of the computer used, directly affecting the overall operating life of the computing device as a whole. If for you, dear reader, all of the above has become news, then it makes sense to think: “Do I follow the manufacturer’s critical instructions regarding operating rules?”.

Why the BIOS suddenly stopped starting: a little about all the reasons

Let’s get down to specifics, because the situation “does not start ”may look different:

  • When you press the “on” button, nothing happens. a black screen and silence.
  • The computer turns on, the screen flickers with a black void (inactive). you hear the noise of the fans and the system speaker beeps (BIOS speaker).
  • The computing device starts, some message is displayed on the screen. the buttons do not respond, except. the restart works.
  • The system boots too quickly (and, safely!), But you can’t get into the BIOS.

There is another interpretation of the voiced problem, when a novice user of the word business understands what exactly is happening and at the same time asks the question, how can I enter the BIOS at all? Let’s start with the last.

At the end

Here is, in short, the entire list of instructions on the problem “BIOS does not start: what to do.” We hope everything worked out for you and access to the basic settings is restored. Of course, do not lose sight of another not described way of fixing the problem of auto products. switch the CMOS jumper to the RESET position (then return the contact element to its original position).

8. Blank disk (no operating system)

A similar problem will occur when the computer has nothing to load the operating system from, since it is not installed on the disk. For example, when buying a new computer or replacing a disk. In some cases. due to damage to the file system and, as a result, loss of the system on it. In this case, you need to install the operating system on the disk.

Also, the problem may be due to damage to the operating system. You can try to solve the problem by reinstalling the system.

Change the battery

If every time you turn off the computer / power supply, the BIOS settings appear, this may indicate that the battery is dead. Also, a signal to replace it may be a CMOS checksum error.

To replace the battery, we disassemble the computer and find it on the motherboard. Roughly, it looks like this:

Cause

As a rule, the problem is caused by the fact that the BIOS cannot find the device from which the operating system should boot. This can happen for the following reasons:

  • The settings of the basic input / output system are lost;
  • There is no media to start the operating system or its malfunction;
  • BIOS software error;
  • Computer malfunction warning. launching the menu signals the presence of an incorrect setting, which can lead to the failure of the PC itself. For example, incorrect bus frequency.

It is also possible that the BIOS startup key (usually Del or F2) is just stuck. because of this, the basic input / output system is constant.

Save settings

The BIOS may constantly appear, since you just need to save its settings once (for example, after replacing one of the components). To do this, go to the “Exit” section and exit with saving the settings. eg:

decision

The solutions are arranged in order of ease of diagnosis and likelihood of occurrence.

Description

Every time you turn on the computer, the BIOS immediately opens (blue window with settings). After exiting it, either the system starts up, or only the BIOS is loaded again.

Very often, this can happen with laptops from ASUS, MSI or Samsung.

Checking the disk drive

We check the performance of the disk on which the operating system (or bootloader) is installed. To do this, you can:

a) See if the BIOS drive sees the Main section.

b) Disconnect the disk from the computer and insert it into another, checking that it is detected and data can be read from it.

c) Boot the computer from the bootable Windows LiveCD flash drive and check the status of the media on which the system is installed, for example, with the CrystalDiskInfo or Victoria.

If the disk is not detected or its condition is determined as critical, then the disk itself must be replaced.

System Restore

The problem can be resolved using a checkpoint recovery tool. Run the system restore again from the Windows installation disk. Then we roll back the system.

Trying to select a point at the moment when the system started normally.

Disable Fastboot

Disabling fast boot in BIOS can also help. To do this, we find the Fast Boot option and put it in the Disabled position. The option itself can be found in one of the sections:

  • Boot
  • Advanced. OS Configuration
  • BIOS Features

note that the “Quick Boot” option similar in name has a different purpose and does not affect our settings in any way, so you do not need to touch this option.

For laptops, it is also recommended to remove the battery after disabling this option.

Black screen. Windows does NOT boot

Quite a common situation. when you turn on the computer Windows cannot load and appears black screen (Not to be confused with blue screen of death).

unambiguous answer, Why does a black screen appear on Windows You cannot give, since there can be many reasons. from a banal power outage (for example, they turned off the light), and you, without suspecting this, in a rage press the computer’s power button, to more serious ones. failure (breakdown, malfunction) of the hardware and a problem with the PC hardware (power supply, processor, motherboard, monitor, etc.).

If nothing happens at all when you turn on the computer. There is NO cooler (fan) rotation noise, no indicator lamps are on, then first determine whether the computer is powered. Check the outlet (with any household appliance), the correct connection of all power and screen cables. Perhaps the wire just came off, it is recommended to disconnect and reconnect them correctly, It will not take long.

Bios Does Not Start On The Computer Black Screen

If you have followed the above steps but a black screen appears when you turn on the computer. we can safely talk about a malfunction of the PC hardware. If your computer or laptop is still under warranty or you DO NOT understand “iron”, then it is better to refer to the service center to specialists. Those who are NOT afraid of experiments can try to eliminate the cause of the black screen on their own, if they are lucky. save money on repairs.

To begin with, completely disconnect the computer from power, disconnect all cables and wires, Remove the side and front panels (depending on which case). Start small. take a closer look at the Power start button, it may just be broken.

Examine the computer “iron” and wires for traces of mechanical damage and short circuit. carbon deposits, soot, if necessary (if the PC is dusty) clean the computer from dust. You can read how to clean your computer yourself at home in this article.

Do not forget to check all the connectors in which the card, RAM and cables are installed. If you find a breakdown, you can save money and replace the hardware yourself or take it to the service.

The most common causes of a black computer screen. failure of the monitor and card. For example, I have them “burned out” from five years after purchase and, strangely, within a month. first “vidyuha” and a month later “burned out” monitor. Probably the time has come. worked for 5 years. and that’s enough)).

In THESE cases, the computer starts up, Windows is loading (sound is heard from the speakers), but there are images on the monitor. Checking is easy and simple. the monitor can be connected to a second computer, laptop, or just to an outlet (if it works. NO SIGNAL will appear). I just connected the TV to my computer (second monitor). the image on it was.

To check the card, this method is also suitable if the problem is in the card. then there will be no images on both displays (monitor-monitor, TV-monitor).

A black screen and freezing of the computer may appear if the BIOS is incorrectly configured. You can read about BIOS settings and recovery by default in this section our site.

There are cases of freezing of a computer with inscriptions on the display with a black screen. Perhaps the mode will help “Last Known Good Configuration boot with working parameters” or “Boot in Safe Mode” and Windows System Restore, if it is NOT disabled in order to save space on hard drives.

program Black screen fix may fix some causes of black screen. You can also reinstall the operating system if the black screen was caused by software.
