Bios does not start black screen with a line. Black screen when loading Windows: what to do if the computer does not turn on. No black screen, computer displays boot messages, but user cannot enter BIOS

Hi all. Today’s article will be to some extent a continuation of the story that we started in the last one about HDD markup styles. It so happened that a computer came in for repair with a rather interesting malfunction. When you turn on the computer, it displays the BIOS picture, and then there is silence - just a black screen. Having gained experience and knowledge from the last article, I decided to experiment a little and solve the problem not with a regular reinstallation, but somehow in a clever way. The ultimate goal is to get a working, starting computer with all the data. Read on to find out how I did this.

How to fix black screen after BIOS splash screen?

Well, the first thing I decided to start with was to actually examine the computer for hardware faults. I started by scanning the RAM. The RAM consisted of one single 4 GB DDR-3 stick. I scanned with an interesting program that was already automatically built into the BIOS, which later turned out (due to UEFI). Unfortunately or fortunately, the scan didn’t show anything bad; everything was fine. Next it was the turn to scan the hard drive. This took a little more time. But here too the result was positive, there were no bad sectors. The resulting picture is interesting, the main tested parts are still working, but the problem with the computer’s operation has not yet been resolved, so we turn on our heads and think about possible options. Then it occurred to me to try resetting the BIOS settings, but it happens, albeit not often, that it is the culprit, but as it later turned out, not this time. The reset was carried out both through the BIOS itself

and using a special button on the motherboard.

All settings were reset successfully, but to no avail. And at this stage I decided to give up on everything and just install Windows 7 from the disk. I insert the original image, at first everything loads quickly, but suddenly, at the moment when I need to select partitions, the installer throws me such a picture.

And then it dawned on me. It turns out that the HDD on this computer is placed using the GPT style in place of the MBR, and perhaps all the problems come from this. Minutes of thought began... the most mysterious thing for me was that Windows 7 was somehow installed on this very computer. Then, of course, I remembered that Windows 7 x64 can see GPT, which means it is installed here. Now the further path to solving the problem for me looked like this:

1. Using LiveCD, copy all the necessary data to an external drive, then delete all partitions and make an envelope using the previous one;
2. Check settings in BIOS, availability of UEFI support, devices in Boot Order;

And as you might have guessed, I took the second path. I went into the BIOS, checked all the settings, indeed it supports UEFI, then I went to the boot devices section and this same boot-order was interestingly divided into two parts, on top of the device (but under the UEFI block), just below almost the same devices ( but under the Legacy block).

In the search, I found the necessary information, and then insight awaited me again :) In the last article, I even touched on this a little. In general, briefly, what is the difference between these two blocks (UEFI vs Legacy). You can boot from your external device the same way, either from a UEFI block or from a Legacy block, but in the first case, your BIOS will use special algorithms that will allow you to see! HDD partitions in GPT style. In the case of Legacy, you will see partitions only if your hard drive is partitioned using the old MBR technology. And this is exactly the gag. Because for some reason my attempts to go to the “System Restore” section (installation disk) always failed. Now, being an expert in this, I again grab the Windows 7 x64 installation image and boot from it. Continue to “System Restore”

This article is about how to reset the BIOS to factory settings. This becomes necessary if you have changed something yourself. This could lead to the following consequences: unstable operation of the computer (PC)/laptop, inability to turn on the PC/laptop, black screen loading the operating system, unknown password to enter the BIOS setup and many others.

Resetting CMOS memory using hardware

Let me remind you that the BIOS is built on CMOS technology (complementary logic on metal-oxide-semiconductor transistors).

Many users respond positively to this method. For many people, after resetting the settings, the laptop monitor started working again, and there were no problems with the image. If this method did not help you, read on.

Detecting a laptop matrix malfunction

If you are faced with a problem when, after turning on the laptop, a black screen appears and the image is not visible at all, then you can use a tricky method to determine whether the matrix and video card are faulty. The method is to connect an external monitor to the laptop. Look at which connectors are on your device and which are on the monitor.

Resetting BIOS Settings

If the problem “the laptop does not turn on and a black screen appears” appeared after changing the BIOS settings, then you just need to reset and roll back to factory settings. This action is performed in several steps.

1. When you turn on the laptop, press the f10 key for 10 seconds to enter the BIOS.
2. Then you need to press f9 and enter to return to factory settings.
3. Press the f10 key and enter - this action saves the settings and reboots the laptop.

7. Reinsert the battery.

In this case, you should contact the service center and consult with specialists.

Reset BIOS

Perhaps the black screen problem appeared immediately after the user made some changes to the basic BIOS settings. In such a situation, it is necessary to reset these same settings and return to the factory settings, that is, the original ones.

To complete this task, you must adhere to the following instructions:

resetting the BIOS (pulling out the battery, and closing the contacts does not help...)

And finally, the power supply, because of which the computer does not turn on at all, we connect the faulty power supply to an electrical outlet, then, as expected, we closed the green (PS-ON) and black (ground) wires on the contacts with a paper clip, then as we see nothing happens, the cooler on the unit does not rotate, in this case it is useless to connect a load in the form of a disk drive, the power supply is faulty.

Also, once I came across a computer that did not turn on due to the melted wires of the additional processor power supply.

As you can see, friends, using a multimeter you can determine whether the power supply is working or not, but unfortunately the multimeter will not help you turn on the computer, so I advise that if you come across a computer that does not turn on at all, then to 100% identify the fault, keep a working unit ready nutrition, this will save you a lot of time and nerves.

The computer does not turn on due to a faulty POWER button

Someone bad kicked it and doesn’t tell you, and this happens, friends, you check the power supply, change the CMOS battery, but the matter is completely different. If, when you press the POWER button, you feel that it is physically faulty, for example, it fails, then you can directly try to turn on the computer bypassing it.

The memory in which the BIOS settings are stored, as well as the motherboard clock, are not non-volatile: there is a battery on the board. Removing this battery resets the CMOS memory (including the BIOS password) and the clock (although sometimes you have to wait a few minutes before this happens).

Note: Sometimes there are motherboards on which the battery is not removable, be careful and do not use unnecessary force.

We do as described above. Return the jumper to its original position.

We launch our “patient” and - oh, miracle! Our ears hear a single short “beep” from the speaker (which indicates that the system has successfully passed the initial POST test), our eyes see the blissful picture of white lines of initialization of all components running across the black screen, the system administrator’s soul wants a holiday and beer! :)

What lesson can you learn from this story? What should have been done first ( completely reset bios settings) was done at the last minute. Hence - a lot of wasted time at the company, but - one good article on the site! :) Conclusion? - any understanding and knowledge comes with experience (positive or negative is no longer so important). So - experiment, gentlemen, experiment! :)

P.S. This computer works stably to this day, and more than six months have passed. You can find a transcript of the BIOS sound signals here (a specialized utility is included in the kit).

Hello! I have the following problem - I turn on the computer, on the first page where the BIOS is loaded, the following happens - it shows the BIOS version, then the memory is scanned, it says that the memory is working in 2-channel mode, then it displays what is connected to the primary mastery, what to slave mastery (HDD and DVD, respectively) - here everything is as usual, but after that the BIOS freezes for an indefinite time, usually for a couple of minutes, after which it just shows a black screen with a white blinking cursor in the upper left corner and that’s it - it won’t load further. I waited for 10 and 15 minutes - it was useless. At the same time, the buttons on the keyboard do not work - not Del, F7, F9, F12 - nothing at all. (including on the first page when loading the BIOS)
I described the essence of the problem. Now about why it arose. The cooler on my processor was malfunctioning. I bought a new one (only 3 pin instead of the box 4 pin). I started putting it on. Before this, I completely disconnected everything from the mother (except for the processor), removed the mother, greased the processor and cooler with paste, installed the cooler, installed the mother, connected everything to the mother. After that the computer stopped booting, at first it didn’t even beep at all. My problem here was that at first I forgot to connect the 4-pin plug from the power supply to the motherboard, and I slightly confused the order of connecting the F-panel (the power button and the HDD operation light worked, the other 2 wires were connected in the wrong place). After I figured out all the wires and connected everything correctly, this problem arose. The first time I solved it in the following way - I completely disconnected all the plugs (including the 24-pin one from the power supply, when I removed the mother I did not disconnect it) and turned them on again. Everything worked. After turning on the computer for the third time, the problem repeated itself. Then the only way to solve the problem was to remove the percentage from the mother and reinsert it
After that, the problem recurred again the 2nd or 3rd time I turned on the computer, I solved it again by removing the stone from the motherboard.
Everything I tried, but only reconnecting the processor helped me:
- completely removed everything from the mother and re-inserted it (including plugs) - video card, memory, HDD, power supply, battery (including resetting the settings to factory settings via the BIOS). By the way, I removed the battery when I couldn’t understand why the computer didn’t boot the first time (when I forgot to connect the 4-pin wire from the power supply to the mother), all the F-panel plugs.
- cleaned and purged the computer
- I changed the paste more than once, by the way, the percent does not heat up, so it’s not a matter of the cooler or the paste - the idle temperature is 39 degrees (it used to be about 50)
I did all the procedures with the power completely off.

BIOS is the most important component of a computer, the activity of which is aimed at setting up the operation of the equipment, checking its functionality, launching the operating system, and more. One of the most unpleasant situations that a user may encounter is when the BIOS refuses to start.
Let's imagine a situation: suppose you decide to reinstall Windows on your computer, but in order to run the installation program, you need to enter the BIOS. You have made more than one attempt to enter the BIOS, and all of them were unsuccessful.

Another situation: when the computer starts, the user first sees the BIOS interface, after which the computer proceeds to load the operating system. In some cases, the user may not see any image at all, that is, neither the BIOS window nor anything else.

Reason 1: Wrong key (combination)

First of all, you should question the correct hotkey you are using to enter the BIOS. Unfortunately, you can only find out which key in your case is by experience, that is, it was not possible to enter the BIOS using one button, next time you should try another.

The process of entering the BIOS is as follows: you reboot the computer or simply turn it on and at the very first stage of turning it on, you begin to repeatedly and quickly press the BIOS hotkey.

There are a huge number of options for entering the BIOS (this is especially true for laptops), but in most cases you will find one of the following keys: F1, F2 and Del. If not a single key helps you enter the BIOS, try Googling the model of your motherboard (for a desktop PC) or laptop model on the Internet to find out how to enter the BIOS for your device.

Reason 2: Non-working or unsupported keyboard

And although in rare cases the user has the opportunity to enter the BIOS without a keyboard, in 95% of cases it is impossible to do without it.

Needless to say, a computer keyboard must be in good working order? Be sure to test the keyboard's functionality by logging into Windows or connecting it to another computer.

If everything is fine with the keyboard, then perhaps the problem is that the keyboard is not supported by the BIOS. As a rule, a similar problem is observed among users of old computers (laptops), and if you use a wired or USB keyboard, then this may well be the case.

If you have a wireless keyboard, then we will need to use a wired one to eliminate the possibility of such a problem. Especially older BIOS versions may not support the USB keyboard interface, but to check this, you will either need to connect an old keyboard with a PS/2 connector or purchase a PS/2 adapter for a USB keyboard.

Reason 3: USB port not working

The port to which the keyboard is connected must be working. Try connecting the keyboard to a different port and try entering the BIOS again.

Reason 4: conflicting devices

One of the computer devices may have malfunctioned, resulting in a conflict, which is why you cannot enter the BIOS.
Try disconnecting everything you can from the computer: drives, hard drives or solid-state drives, all USB devices connected to the motherboard, PCI cards. If there is a built-in video card, then disable the discrete one, and then try to enter the BIOS again. If the attempt is successful, connect one device to the computer at a time to find out what is conflicting. Having identified a problematic device, it is precisely this device that you will need to deal with (it is better to take it to a service center for diagnostics).

Reason 5: Computer malfunction

If, when you turn on the computer, the BIOS starts making sounds, but does not want to start, you should listen to the signals and record them. Often the BIOS uses such signals to make it clear what went wrong. There are a lot of tables on the Internet that decipher sound signals for different BIOS versions, using which you can quickly understand the cause of the problem and begin to fix it.

Reason 6: Problematic BIOS settings

As a rule, a similar cause of the problem occurs when the user makes changes to the BIOS. In this case, you should try returning the BIOS to factory settings. As a rule, in most cases you will need to look under the system unit case, where on the motherboard you can find a special switch (CMOS jumper), which is set to position 1-2. To perform a reset, just move the switch to position 3-4 for 15-30 seconds, after which you can return it to its previous position.

Reason 7: Problems with the motherboard

The most unfortunate cause of the problem, since the motherboard is almost the entire computer. If you suspect a problem with its operation, you can carry out a short diagnostic procedure.

First of all, you will need to inspect the motherboard itself: is there any oxidation, are the capacitors swollen. Any external changes indicate its malfunction, which means that all this must be eliminated. If there is oxidation, it must be carefully erased with an eraser. If the capacitors are swollen, they should be soldered with new ones.

If visually everything is fine with the motherboard, you should try the following:

1. Disconnect your computer from the network, and also remove all unnecessary devices: mouse, speakers, keyboard, any additional devices and cables. As a result, only a network cable and a monitor need to be connected to the system unit.
2. Reset CMOS. To do this, you should remove the battery from the motherboard for a few seconds and then install it back.
3. Remove all cards from all motherboard slots, leaving only the processor and speaker connected.
4. Start the computer and pay attention to the sound: if there is any sound, this tells you that the motherboard is working. If not, then everything is much sadder - she does not respond.

If you have confirmed your guess that the problem is in the operation of the motherboard, you should try to take it to a service center - it is quite possible that a specialist will be able to restore its functionality.

These are the main reasons that influence the BIOS not starting. If you have comments on the article, leave them in the comments.

Question on the forum:

My screen doesn't show. I was advised to take the laptop apart and take a look. I've never taken a laptop apart. What does this mean for me?

You'll never get it together. 😀

Imagine this situation: one day you turn on your computer or laptop and see that it won’t start; Moreover, you discover that the BIOS does not load. Surely those readers who have encountered a situation where a computer or laptop does not boot or even start, are unlikely to have found it pleasant. In addition, it may happen that the computer or laptop turns on by itself and loads the BIOS and operating system, but you cannot enter the BIOS, that is, the BIOS Setup computer settings program does not start. In this article we will try to give advice on what to do when a 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 the BIOS Setup does not load, and how you can solve these problems .

When a computer or laptop does not boot, as a rule, instead of the familiar BIOS messages, the user sees only a black monitor screen in front of him. Sometimes a black screen on a computer or laptop is not a constant companion to this problem. For example, you turn on a computer or laptop, and you see that the system initially boots, some BIOS messages are displayed, but the boot process does not go beyond this stage, and the operating system does not start. What to do next in this case? First of all, you should not immediately panic and take your computer or laptop for repair, since you can try to solve this problem yourself.

The reasons that a computer or laptop does not start or the BIOS does not load can be due to various malfunctions, both related to the computer’s BIOS and those related to the PC hardware. And the solution to the problem “the computer does not load the BIOS” in this case largely depends on its cause.

Types of situation:

• 1. 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 when booting. One short beep usually means that the BIOS has successfully checked the hardware.

• 1.1. Black screen and one beep

In this case, the cause of the problem is most often the monitor (of course, if we are talking about a desktop computer). Therefore, it is best in such a situation to check the connection between the monitor and the computer or the power cable of the monitor. If the computer does not start even after this, and the black screen remains, then the problem is not with the monitor.

• 1.2. Black screen and several beeps

The presence of several signals at the moment when the computer turns 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 don’t see anything on the screen, then the problem is again related to the video system, but this time, most likely, with the video card. However, in order to be completely confident in this matter, it is best to refer to the list of conditioned sound signals for the BIOS version that is installed on your computer or laptop.

• 1.3. Black screen and no beeps

If the computer turns on, but the “black screen” is not accompanied by any sound signals, then we can assume 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 motherboard. Or there is simply no contact between the motherboard and the power cable. The cause of the problem may also be a malfunction of the BIOS itself, the motherboard, processor, memory, or even the hard drive. In addition, sometimes the reason that the computer does not boot may be insufficient cooling of the electronic components of the motherboard.

• 2. There is no black screen, the computer displays boot messages, but the user cannot enter the BIOS

It is worth mentioning separately about the situation when the computer turns on, but there is no “black screen” and the system boots normally, but does not enter the BIOS program for setting up computer parameters - BIOS Setup.

• 2.1. The BIOS entry key is pressed incorrectly

True, there is one nuance here. Some users may immediately panic “I can’t get into the BIOS,” although they simply do not know how to correctly enter the BIOS. To enter the BIOS, you simply need to press the appropriate key after the computer turns on. But many users press the wrong key or do it at the wrong time and that is why they cannot enter the BIOS. We wrote about what needs to be done to enter the BIOS setup program after the computer turns on in the corresponding article.

• 2.2. The BIOS entry key is pressed correctly, but still cannot enter the BIOS

But it may also happen that BIOS Setup does not start, and you cannot enter it even though the correct key seems to be pressed. Most often, if you press the desired key and cannot enter the BIOS, the keyboard is the culprit of the problem. For example, if you are using a USB keyboard and the BIOS does not support USB devices, you will not be able to enter BIOS Setup. In addition, it is worth checking the functionality of the keyboard on another computer. If the BIOS does not open even after eliminating the keyboard factor, then the problem is in another component of the computer.

• 3. Stop by BIOS information messages

It is also not uncommon to encounter a situation where the computer starts, but does not load the operating system, but displays a text message about a certain error on the screen when loading the BIOS. Continuing the download depends on the nature of the error. For example, a BIOS checksum error message may indicate that the CMOS battery is low, and in this case the user can usually continue working after pressing a certain key.

Ways to solve problems

First of all, in order to solve the problem and eliminate the reason why the black screen appears and the computer does not load the BIOS and operating system, you should remember what you were doing before the problem occurred? Did you install new devices on your computer just before the black screen appeared? Have you made any changes to the BIOS settings?

If you did make changes to the hardware, it is recommended to return the system to its previous state by removing the recently installed hardware. If after this the computer works normally and loads into the BIOS, then this means that the problem was with the remote hardware.

If you made your own BIOS settings, you can return the BIOS to safe factory settings. To do this, as a rule, it is enough to install a special CMOS memory reset jumper on the motherboard or remove the CMOS battery. As a rule, this operation often helps when the computer does not load the BIOS.

If you know for sure that you did not perform any actions with the BIOS or equipment, but the computer or laptop still gives you a black screen and does not load the BIOS, then you will have to check all the equipment yourself.

Sometimes the cause of a malfunction may be dust in the “insides” of the computer. Therefore, the very first procedure for any user trying to revive a computer is to clean the internal space of the system unit. Only after this will it be possible to move on and check the functionality of all systems.

Temporary system failure is also possible due to overheating of the processor or motherboard. Therefore, it is worth checking the coolers of the system unit and processor. Then, one by one, you should check the main components of the computer - processor, RAM, motherboard, video card, power supply. A hard drive failure will rarely cause the BIOS to not boot, but this option should not be discarded either.

Conclusion

The situation when the computer does not start and does not load the BIOS and OS, and the user sees only a black screen in front of them, of course, cannot be called pleasant. Since in this case the computer cannot be used for its intended purpose, as a business or entertainment tool, this is a great inconvenience for the user. However, the situation when the computer BIOS does not start is not always as fatal as it seems at first glance. Since it is extremely rare that the computer freezes and the inability to load the BIOS or the inability to enter BIOS Setup is a symptom of a hard drive failure, the user does not lose important information recorded on it. In addition, there are a number of methods that allow you to identify a faulty element and revive your computer. Of course, in some cases it may be impossible to identify a malfunction by the user, and then it is best to use the services of computer specialists from a service center.

I don’t want to be trivial, but the so-called “black screen problem” when loading the operating system after turning on the computer is one of the most common problems faced by owners of both desktop computers and laptops. An operating system that won't boot or a hard drive model doesn't really matter when diagnosing the problem. We will tell you further about how to remove the black screen when loading Windows 7 on a computer and laptop, and the reasons for the failure.

This guide will be updated, so do not hesitate to ask questions, I will clarify technical points as best I can and solve your problems with the black screen.

The most likely causes of a black screen on boot

First, you need to list the most common problems that cause a black screen, after which the operating system does not load (in other words, a black screen when you turn on the computer). In rare cases, after loading the user sees not only a black screen, but also a cursor. Reasons:

1. There is a conflict in the operating system, due to which it cannot load the graphical environment normally.
2. Video driver problem (incompatibility with the current operating system: for example, Windows 10 or Windows 7, up to XP)
3. The hard drive on your computer or laptop has failed
4. Windows OS has crashed and does not boot correctly (not in safe mode)
5. Other hardware problems or system conflicts
6. Windows can't wake up from sleep state

Start Windows in Safe Mode on your computer

One of the most likely reasons why Windows or another operating system does not boot is a system conflict due to which the OS cannot work correctly after turning on the PC. This may be caused, for example, by the fact that the user installs an incompatible program or drivers that conflict with Windows, and when turning on the laptop/PC, the conflict will make itself known in an unpleasant way - in the form of a black screen. How can I remove it?

Fortunately, Windows developers have provided the ability to log into the operating system in a safe mode, which is designed specifically to eliminate various compatibility issues. By entering safe mode, you can fix all problems on your computer, resolve conflicts, and then boot Windows into normal mode.

So, to enter safe mode on your computer:

1. Remove from the computer all media and devices that may affect Windows boot (flash drives, disks, etc.)
2. Restart or turn on your computer, depending on its current state.
3. To enter Safe Mode, hold down the F8 key while booting. If your PC (laptop or desktop version) has several operating systems, then select the appropriate one from the list and then press F8 again to enter Windows Safe Boot Mode.

Problems with the monitor or components

The reason for the black screen may be obvious: the monitor is not working. This may be due to the fact that the contact between the monitor and the video card is lost or the power cable is damaged/not plugged into the outlet. So be sure to check your connection.

As for the laptop, it is unlikely that the matrix “fell off” from the motherboard. To disable it, you need good reasons: for example, mechanical impact on the display. In this case, you will see that there is obvious damage on the screen: scratches, dead pixels, etc.

In addition to the monitor, we recommend examining the system unit. Check whether the video card is secured in the corresponding socket on the motherboard and whether voltage is supplied to all PC components. This should only be done if you have the skills to assemble/disassemble a computer/laptop.

Resolving conflicts with the video driver, if the computer does not start, a black screen is displayed

An example of a similar problem:

Installed Windows 7, 10, restored to factory settings (native Windows image). But nothing helps. Simply put, when you turn on Windows 10 for the first time, everything is good and everything is fine, but when the drivers are installed on the video card (intel hd3000 and radeon 7600), flickering and a black screen occur, after which recovery and safe mode do not work. That is, Windows 10 dies, after installing the drivers there is a black screen.

If you think that the black screen problem may be due to a conflict in the video card drivers on your computer or laptop, then:

1. In the Secure Boot menu, select "Enable low-resolution video mode."
2. After successfully logging into your operating system account through Device Manager or Control Panel, remove the conflicting ATI/NVIDIA video driver.
3. Restart your computer
4. There may be a conflict between the drivers of the motherboard and video card. You need to try different driver combinations. To avoid reinstalling Windows each time when experimenting, create a restore point and when a black screen appears, roll back to the previous restore point.
5. If the OS loads correctly in normal mode (the Desktop and Windows cursor appears), then the black screen problem is really related to incorrect behavior after installing the drivers. Go to the video card manufacturer's website and download the latest version to your hard drive, try updating the drivers again.
6. If the black screen continues to appear, try other solutions to the problem outlined in this guide - for example, uninstalling harmful programs.

We remove programs that conflict and block the OS from loading when turned on

Windows 7 does not start for me. When I turn on the computer, after the words “start Windows,” a black screen appears and the computer does not boot. There is no cursor. I restart the computer, I am given a choice of how to boot Windows, I select normal mode - and everything turns on, sometimes I need to restart several times. Normally it doesn’t turn on at all, I have CCleaner, I use it, the antivirus is Avast, I don’t update any drivers. What could be the problem?

In this case, the sequence of actions to fix the problem will be approximately the same as in the above case. The only thing is that in Windows Safe Mode you need to select the “Enable Safe Mode” option. Next, in this download mode, you need to go to the control panel and in the “Programs and Features” window, sort by application installation date. Analyze what you have installed recently: perhaps conflicting applications are the cause of the black screen and inadequate loading of Windows from the system drive on your computer. One of the best programs for uninstalling applications is the free CCleaner utility.

Disable unnecessary programs and services from Windows startup

There is a wonderful utility called msconfig, with its help you can speed up Windows boot. Although modern computers load the OS quickly, boot optimization can eliminate the black screen for a few seconds.

1. Start - Run. Enter msconfig in the window.
2. Services tab - here you can disable unnecessary services.
3. Startup tab - to enable/disable programs during startup.

In Windows 10, startup items can be disabled through the task manager (Startup tab). The status column displays the status of the application.

We use a restore point to perform a system rollback on the computer and fix problems on the computer

It happens that the cause of the OS failure cannot be identified; removing drivers and programs that cause conflicts does not help: a black screen still appears when the computer boots.

If the computer does not start, use the previous Windows restore point

We use a boot disk (Live CD) to fix errors and diagnose a black screen

When a black screen appears, it is advisable to check your computer and operating system for viruses. This can be done using a "live CD". We recommend using the 4MRescueKit boot disk to enter system recovery mode. In addition to the virus scan itself, livecd 4MRescueKit includes modules for data recovery, file backup, and a disk manager like PartitionMagic. Even if this does not help get rid of the black screen of death, you can at least prepare to reinstall the operating system or diagnose the performance of the hard drive in this mode. Live CD fixes problems regardless of the version: it can be both Windows and Linux.

The 4MRescueKit boot kit helps fix software errors on the disk

Black screen during Windows reinstallation

I get a black screen and a cursor, I reinstalled Windows and I still can’t completely reinstall it. After the first reboot, during the installation process, when loading Windows, there is a black screen and cursor.

Solving the problem.

1. Try using a different installation disk or version of Windows OS.
2. The reason for the appearance of a black screen and interrupted loading can be either software or hardware. For example, the hard drive contains bad sectors or the USB flash drive or the disk from which Windows is installed is damaged.
3. Try installing the operating system on a different partition of your hard drive.

Viruses have damaged Windows system files

Many computer viruses can delete or damage important system files. As a result, after Windows loads, a black screen appears, although the cursor can still be displayed and respond to your movements. Removing viruses does not always help solve the problem, but you can try.

How to check your hard drive for viruses if Windows won't boot? You need a working computer to which you can attach a hard drive. After booting into Windows, install the free Dr Web CureIt antivirus. The CureIt utility contains current virus databases.

Video instructions:

Select the hard drive to scan and launch the scanner.

If, after detecting viruses, a black screen still appears when loading Windows, then you need to look for other reasons.

Burn a recovery flash drive and reinstall Windows

After updating Windows 7 - black screen in any mode: normal, safe - no difference. I tried restoring Windows via the installation disk - to no avail.

Answer. Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: update and solve the problem with the black screen when loading Windows 7.

One of the best programs for burning Windows to a USB flash drive is Rufus. The utility is available in Russian, it is free and, as a rule, burns trouble-free USB flash drives for installing Windows.

The worst thing that can happen: the hard drive fails

Finally, one of the most pessimistic outcomes. If you see a black screen and the cursor is still visible, then the hard drive is working. If there is nothing but a black screen and the OS does not load, then it is quite possible that the computer does not see the hard drive and, accordingly, Windows does not boot. By following the link you can read the manuals that will allow you to diagnose your hard drive and find out whether it is possible to make repairs, restore data by loading the operating system, or is it better to immediately go to the store and purchase a new HDD for your computer or laptop.

Resume. In this guide, I tried to remember and collect from the Internet the most complete list of problems that cause a black screen to appear on a PC. The OS version doesn't really matter, it's Windows 8, Windows 10, or the outdated XP. If none of the methods helped, something is unclear, or you have your own ways to solve this problem, please ask questions and add your ideas in the comments.

Answers to readers' questions

I have a black screen after loading Windows, I tried everything, but nothing helps: I turn on the computer - a black screen, and nothing can be done about it. The bottom line is that the black screen appears only after I update the drivers for the video card. If you install standard VGA, then everything starts and works fine.

Before this, I completely reinstalled Windows and it all started somehow unexpectedly with “nothing”. How to fix black screen when loading windows?

Answer. One of the surest ways to resolve OS and driver conflicts on your computer is to go to the website of the manufacturer of your video card and download the latest drivers or stable ones, not in beta, to disk. When downloading, make sure to specify your operating system in the same bit depth (32- or 64-bit). It is also possible that your video card is outdated and not supported by modern operating systems, in particular Windows 10.

If your laptop has a black screen, try updating the drivers

I have Windows 10 installed. An attempt to restore the OS from a system image failed. Now there is a black screen with a cursor flickering in the upper left corner when turned on. All I can do is turn on the computer and enter Bios.

Answer. If you only see a black screen and a cursor, this is a sure sign that the operating system cannot boot (you already understood the problem).

If the recovery console or Windows 10 installation disk does not help to roll back the OS to its original state or restore point, create either a new disk to restore or install the operating system from scratch.

Not a single folder opened, so I decided to run . A black screen with a cursor appeared on the laptop when turning on / starting Windows OS. I did everything according to your article, but the screen is still black. Help please.

Answer. If a black screen appears when you start Windows even after recovery, it makes sense to reinstall the operating system on your laptop in another way - for example, in boot mode from a flash drive or disk. Since, according to your description of the problem, the cursor still appears on boot, this is a software error, not a hardware error.

An external box was connected via USB to format ext3 using PartitionMagic. After formatting was completed, the laptop restarted and there was no reboot, and a message appeared on the black screen: error loading operating system... The laptop no longer boots, does not respond to any keys... OS XP... what to do, it’s practically That's it, there is a 2nd PC with Windows 10. In other words, the laptop works - but the screen is black.

Answer. Luckily, your laptop is dealing with a software glitch and not a hardware failure. All you need is to reinstall the Windows operating system. After this, the black screen of death will no longer appear. If your laptop has a disk drive, use a boot disk to restore the OS. Otherwise, it will help you, it’s not difficult to write it down, read the instructions at the link.

I get a black screen when I turn on my computer. Nothing appears on the monitor when I turn on the computer and the system unit is running. I did one trick: pulled out the power, held down the power button for 5 seconds, released it, inserted the power cord, turned on the PC - everything worked fine. After 3 days the same thing happens, but this trick doesn't work. I think this is an incorrect shutdown. I turned it off the last time when some programs were still running (Windows 7 for me) and the Desktop did not appear after loading. What to do if your computer has a black screen?

Answer. You need to approach the problem comprehensively: figure out whether the motherboard and power supply are working correctly in general, whether all the wires are connected to exactly the right power connectors, whether the PC components are tightly connected to the sockets (for example, very often the “black screen of death” is associated with an incorrect connection video cards). Perhaps the problem is not hardware, but software (but it’s not clear from your question whether Windows boots). In this case, reinstalling from a boot disk or restoring in LiveCD mode will help.

Help me understand what's wrong with the PC. I have Windows 7. After the startup starts, a black screen and a cursor appear, after which I am asked to select Windows 7 and the recommended boot or the normal one. After clicking them, the download starts and throws you back into the same settings. The same problem occurs with loading in safe mode. It does not offer anything further, there is no window for entering explorer.exe.

Answer. If, when you try to boot Windows 7, a black screen and the cursor continues to appear, no matter what mode you selected, most likely the Windows system files have been deleted or changed. A clean reinstallation of the OS or recovery from a Windows 7 boot disk will help. In the boot menu, select “System Restore” and then use the Bootrec.exe utility. Further actions are described.

I have an AMD Radeon video card with 512 MB of memory, it did not support new toys, and I found on the Internet how to increase the memory of the integrated video card via bios. I changed some settings in the BIOS and installed 1 GB of memory, my PC rebooted and I looked at the characteristics of the video card and yes, in fact, the memory has increased. Then I started playing games, about an hour passed and my mouse began to freeze, turn on and off, and then stopped working altogether, I decided to restart the PC and then on my monitor I saw just a black picture with some number in the corner. The computer refused to turn on, after probably half an hour of clicking on the mouse and keyboard, “welcome” appeared on the screen. The PC turned on, but the mouse still did not work, I rebooted again - and again there was a black screen for a very long time when the computer booted. What could this be and how can I get rid of it?

Answer. This is what overclocking a video card leads to. You need to go into the BIOS and reset the settings to factory (default) settings. Perhaps it is because of the BIOS settings that Windows does not start.

You're in luck: with such overclocking of a video card, problems with the temperature of the video card may arise, up to the failure of one of the components (for example, the processor).

In general, you can’t always trust such overclocking instructions. Even if it contains correct information, if you do not have the proper skills, you can get not only a black screen, but also black smoke from the system unit :).

I don’t know why it started, maybe after defragmenting the hard drive, after updating drivers, etc. Every time, before Windows boots, a black screen is displayed for 10 minutes and only after that the welcome window appears. The BIOS definitely loads first, I pressed F2 to check the boot device priority in the BIOS. Also, during a black screen, the console carriage (lower slash) sometimes appears. What can cause a black screen when loading Windows?

Answer. In the BIOS, you can not only set boot priority, but also disable unnecessary devices (for example, a disk drive). However, this will not save the situation.

Perhaps the reason is that when Windows boots, it tries to find the required library or load a non-existent component. Go to the startup menu and disable all unnecessary items. You can also disable unused Windows services via msconfig and remove unnecessary applications on your computer. In general, it is desirable to optimize the operation of the operating system and eliminate conflicts.

You can also analyze the stages of Windows boot using the built-in Event Log Viewer tool. This utility will show how long it takes to load each process when the OS starts.

If time permits, reinstall the OS. On modern computers, reinstallation takes no more than half an hour, and this is a more rational way to solve the black screen problem than spending hours troubleshooting. Sooner or later, any Windows OS develops problems.

I have Windows 7 on my computer. Everything was fine, but one day after entering the bios password there was no Windows boot icon, and the monitor turned off (went into power-saving mode), the f8 key does not work. I can’t enter bios because the monitor doesn’t work.

Answer. Try resetting the BIOS by removing the battery from the motherboard.

Let's move on. The energy saving mode will not work immediately after the computer starts; rather, the problem is related to one of the components. Check the connection between the video card and the motherboard, the video card and the monitor, etc.

If everything is fine with the BIOS and Windows 7 does not boot, reinstall the OS. Apparently, this is the easiest method to get rid of the black screen.

Windows 7 32bit OS was installed. After changing to Windows 7 64bit, a black screen began to appear. When connected to the TV, everything works, everything is shown, everything is fine. But it doesn’t see through the VGA monitor and the screen is still black.

Answer. Perhaps the 64-bit version did not install drivers for the monitor or video card. Check on the manufacturer's website whether the monitor supports this OS. There is a suspicion that your specific VGA monitor is not supported by this edition of Windows. Try booting Windows in Safe Mode or with the "Enable low resolution video mode (640×480)" option.

I'm using VirtualBox. I installed Linux, worked on it, then turned off the virtual machine. When I tried to launch it, after loading there was a black screen with an underscore at the top left. The laptop itself works, the virtual machine does not.

Answer. If you save the state (Suspend) on the virtual machine, in principle, no problems should arise. If you turn off the virtual machine, then Linux tries to boot when you turn it on. Why a black screen with an underline appears after rebooting Linux is a separate question. Check the key settings of the virtual machine. If the error persists, try installing Linux on Vmware Player.

I have this problem. It's Windows 8.1, I installed a third-party theme, I decided to delete it, I deleted the entire themes folder from Windows, although not all the files could be deleted, that's okay, I rebooted the computer and after selecting the OS I got a black screen and, no, no, the cursor appears and disappears and bottom toolbar, tell me how to get rid of the black screen? There is no restore point, no image, and no disk with the OS.

Answer. If possible, find a bootable image of USB Boot or the like on the Internet, write it to a flash drive. Find the Themes folder on the Internet or on a disk and, with administrator rights, copy it to the previous location from which you deleted the files.

Without an installation disk, it is unlikely that you will be able to get rid of the black screen in any other way.

When I turned on the computer, nothing appeared. The light shows that the camera is working and the computer is turned on, but the screen shows zero. What is the problem - RAM or hard drive? How to check?

Answer. To diagnose the problem, it is advisable to recall previous events. Did your computer show any symptoms of failure (hard drive noise), did you delete system files on the drive, etc. This will help narrow down the list of possible causes. Next, watch at what stage the black screen appears. If the hardware initialization is successful, then the problem is in the operating system - that is, Windows does not start. In this case, we recommend reinstalling the OS from a bootable USB flash drive or disk.

Good afternoon Since the evening the computer has been freezing. In the morning I turned it on on the screen - it is necessary to restore the device, error 0x00000e9. I tried to restore via input and the F8 button, as indicated, there were no changes on the screen. I turned off the computer and touched all the wires. I turned on the black screen, I turned it on and off several times, still no change in the black screen. Now I installed the Windows disk, the system unit beeped, you can hear it starting up, but still the black screen. What should I do next?

Black screen on startup. The indicators are all on, I tried just rebooting, it worked the first time, but then the black screen again. I connected it to the TV, everything worked well, what's the problem?

Windows 7 boots fine for me at first. But if you turn off the computer and turn it on again not after 10 minutes, but earlier, a black screen appears without a cursor. At the same time, the monitor light blinks, which, as I noticed, indicates that the screen will be black all the time. But still, after this, Windows 7 loads - as evidenced by the Windows 7 welcome sound, but the screen still remains black and the cursor is not visible. To turn it off, you have to press the button on the system unit. My video card drivers have been updated to the latest version from the manufacturer's website. System Restore doesn't work. Viruses and malware have been removed. How can I remove the black screen?

During the installation of AMD drivers, the brightness suddenly disappeared. Rebooted, the boot selection menu is activated. When turned on normally, the brightness is very low, you can only see anything with a flashlight. The brightness is at standard, but the screen is dark. OS Windows 7. Please tell me what to do.

I have Windows 8 installed at work. Empty. Well, a couple of small files. It takes a long time to open the file. And it generally takes a long time to load. In another office on the computer, I also made a bootable USB flash drive on it. Can I use it to restore my computer? When restoring on mine without a flash drive, it says that “some files are missing. Insert a recovery disk.” since I am only a user. I'm afraid of completely screwing up the system. But it works fine and loads normally, it just takes a long time.

Hello, this situation happened. The Lenovo tablet has stopped working; when I press the power button, the screen does not respond, but the backlight is visible. The screen was broken, but a year had already passed since that incident and everything was working well, and in the last few days the screen simply went out, in parts, but immediately responded to being turned on. What could this be and how can I fix it?
