Doesn't load from. What to do if the above instructions did not solve the problem

Hello, dear readers, Trishkin Denis is in touch.

Working at a computer for a long time, many users encounter a situation where Windows 7 simply does not load. Moreover, each individual case has its own manifestations. To understand this topic in detail, I will try to consider the most common options. Despite the fact that there are many of them, there is still a certain classification.

There are many options due to which the operating system refuses to work as usual and a black screen appears:

hard drive problems;

the device boot queue is set incorrectly;

a flash drive is inserted into the USB port;

• problems with RAM;

  Incorrect installation of updates.

The system starts only in safe mode( )

Sometimes users may encounter a situation where Windows boots only in safe mode. First, you need to try to remember what could have caused the malfunction. Often the reason is the installation of a new application. In addition, the most popular reasons include clicking on advertising banners on the Internet, changing hardware settings, and connecting new devices.

To solve the problem, you need to try to return everything to the way it was before the malfunction occurred. If the problem appeared after installing the program, you need to remove the latter:

If problems arise as a result of connecting the device, we take other actions. I recommend using this method even when the blue screen of death appears just like that, without any hardware or software changes.

So, let's do the following:

You can learn more about the problems that cause the death screen to appear by going to.

Stuck on greeting( )

Often, users may experience a situation where Windows does not load beyond the greeting. That is, they see the inscription: “”, and that’s where it all ends. As with any other problem, there can be many reasons. We will highlight only a few of the most common ones.

If problems appear after clicking on an unverified link or as a result of installing dubious software, it is advisable to use antivirus software. To do this, you need to boot into "" using the "" button F8" And launch the appropriate solution. At this time, you can independently shut down suspicious programs in “ Task Manager».

Windows may freeze at the logo as a result of insufficient thermal regulation of the hardware. This may be preceded by non-working coolers, dried out thermal paste, and a huge amount of dust. To establish this reason, it is enough to use one of the utilities that shows the current temperature conditions. It is necessary to compare the readings with the data from the documentation. If they exceed those written in the passport, you need to urgently clean and, if necessary, replace individual components.

This element may also overheat. In addition, problems occur as a result of mechanical damage to the component. To determine the exact cause, some tests need to be performed. You can read more.
If the result turns out that the malfunctions are due to overheating, it is necessary to use appropriate heat sinks. With their help, users can significantly reduce the risk of running out of RAM.

In some cases, only replacement helps. The main problem is that manufacturing defects can appear even several months after active use.

Sometimes operating system problems are directly related to the operation of the hard drive. These can be logical, electronic, or mechanical errors. Often a harbinger of problems is unusual sounds emanating from the relevant equipment. How to check and other information can be read in.

Updates( )

In some cases, the operating system refuses to work after an update. The main thing is to remember whether the corresponding screen appeared the last time you rebooted or shut down the system. If yes, you need to try to restore Windows functionality by rolling back to previous versions. This can be done from a disk on which there are files for installing the operating system. You can also try to boot from a flash drive.

Sometimes the option “ Loads the configuration with the last working parameters", which can be selected by pressing " F8"during the start of the equipment.

If you are not sure that the problem can be solved solely by reinstalling Windows, you should use other options to restore functionality. You can find out more details from.

As you can see, there are many reasons why the Microsoft operating system may not want to boot. Moreover, each of them is solved with its own tools.

I hope you can find the right option for you. Subscribe and tell others about my blog.

Why won't Windows 7 start? Loading the operating system may fail for a variety of reasons: due to a hardware failure, due to incorrectly installed software, due to viruses, but most often due to problems in Windows itself. To make the description of the process of searching for the source of the failure more clear, we will first analyze the startup sequence of the seven.

Windows 7 Boot Steps

The launch of Windows 7 is conventionally divided into three stages, which are divided into phases.

1) OSLoader

OSLoader- the first stage of booting Windows 7, which begins immediately after executing the BOIS code. At the beginning of this stage, a small group of basic drivers is loaded, necessary for further reading data from the hard drive. Further winload.exe, Windows 7 boot loader, proceeds to initialize and start loading the kernel, loads the registry hive into RAM SYSTEM and the next batch of drivers with the launch parameter BOOT_START.

Stage OSLoader lasts 2-3 seconds. By the time the system logo appears on the screen, it is already completed.

2) MainPathBoot

MainPathBoot- the main and longest stage of loading Windows. Consists of several phases. Visually, this stage continues from the appearance of the system logo on the screen and ends with the start of loading the desktop. The duration of this stage can vary - on average, from ten seconds to a couple of minutes.

• PreSMSS phase

During this phase, the Windows 7 kernel is fully initialized, the plug and play hardware manager is launched, and previously running drivers are initialized BOOT_START and hardware drivers.

Errors that occur during this phase are often related to problems with the main computer devices or their drivers.

• SMSSInit phase

The phase begins when control is transferred to the session manager - SMSS.exe. At this time, the remaining registry hives are initialized and drivers are loaded with the “auto” launch parameter. At the end of the phase, control passes to the file Winlogon.exe- Windows user login program. Visually about the end SMSSInit indicates the appearance of a login prompt on the screen.

Crashes and slowdowns during this phase are often due to delays in loading the video driver or problems with the video subsystem.

• WinLogonInit phase

This phase begins at the start Winlogon.exe(welcome screen) and ends with loading the desktop - the start of the Windows shell - file Explorer.exe. During its progress, the system reads and executes group policy scripts and starts services (system and third-party). The phase can last quite a long time and be accompanied by high processor load.

Failures at this stage are often caused by third-party application services, including antivirus.

• ExplorerInit phase

It begins with the start of the shell and ends with the start of the desktop window manager process. During this phase, desktop icons appear on the screen. At the same time, services are launched further, startup applications start, data caching, etc. All this is accompanied by a high load on hardware resources - hard drive, memory, processor.

Problems and delays during ExplorerInit often associated with insufficient power or equipment malfunction.

3) PostBoot

Stage PostBoot begins with the appearance of the desktop and ends after loading everything that is registered in autorun. During this period, the bulk of applications launched with Windows begin to work. After the end of the stage, the system goes into inactivity.

Delays and failures at the stage PostBoot are associated with startup programs, sometimes with viral activity.

Failures at various stages of system boot

As already briefly mentioned, problems at different stages of the Windows 7 startup manifest themselves in different ways: some are related to the hardware, others to the drivers, and others to the system registry or other boot-critical files. By understanding what processes occur at each stage of system startup, you can determine the range of possible problems.

Briefly about hardware problems

We will not dwell on hardware problems in detail, since our topic concerns Windows 7, but sometimes it can be very difficult to determine what is broken - a physical device or a system.

• Repeated failure of the same driver at Windows startup may be due to a malfunction of the device controlled by this driver.
• A series of various errors (blue screens of death) that occur at different boot stages are often caused by RAM problems.
• The absence of an image or artifacts on the screen, while the sounds of the system booting can be heard, may indicate problems with the video card.
• If Windows does not even start loading or suddenly stops - “freezes” in one place - it is possible that the hard drive is failing.
• Sudden shutdowns of the computer while Windows is loading indicate problems with the power supply or motherboard, and sometimes something else.

Corrupt boot files

During the early stages of Windows startup, damage or missing critical files may be indicated by the display of the phrase "Bootmgr is missing" or other error messages. But it happens that no messages are displayed, and the user simply sees a black screen with or without an arrow cursor.

The loader of the Windows 7 and 8 operating systems, like other boot elements, is inaccessible to the user - it is located in a separate hidden partition and cannot be accidentally deleted. However, the user may unknowingly format this partition by booting from external media. Then Windows will not boot.

The screenshot shows the boot partition of the hard drive accessed from the recovery environment.

Another part of the files important for downloading is located on the system disk in the directory and subdirectories C:Windows. The system registry is also located there.

Registry corruption

If the registry is inaccessible or damaged, Windows may not even start loading.

The system itself will inform you about the failure and automatically launch the built-in recovery wizard. It often helps to identify and fix the problem - the registry will be restored from a backup.

But self-healing Windows 7 booting is not always possible. Thus, it does not occur if the recovery wizard cannot find backup copies of missing or damaged data. In these cases, the system needs the user's help.

Windows 7 startup recovery

Recovery environment

Restoring the boot of Windows 7 is much more convenient than Windows XP, because the seven is equipped with a set of tools Windows Recovery Tools (WRT), which is accessible from the recovery environment. The recovery environment during Windows installation is installed on the hard drive, in a separate partition, and has its own boot loader. Therefore, it remains operational no matter what happens to the system.

To get to the recovery environment, select from the menu F8(Windows 7 Advanced Startup Options Menu) "Troubleshooting your computer".

To access the recovery options, the system will ask you to enter a password. If you do not have administrator rights or have forgotten your password, you will have to run Windows 7 Recovery Environment from the installation disc.

After the window opens in front of you "System Recovery Options"- select the first option from the list: "Startup Recovery". After self-diagnosis, damaged boot files, registry or individual startup parameters will be restored.

This tool helps solve the problem in most cases, and should be used when you don’t know exactly why Windows won’t start.

Two ways to restore the system

If the failure occurred after installing the program, due to a virus infection or due to changes in the registry, it will help to restore the ability of the seven to boot "System Restore". But it will only be useful if recovery checkpoints have been saved on the hard drive.

The way this tool works is familiar to many: you select a suitable checkpoint when the system was functioning normally and perform a rollback. Any changes made after the selected date will disappear and you will be able to boot into Windows normally.

If there are no points, but you saved a backup copy of the system on an external drive, the tool will help "System Image Restore". Connect the media with the archive image to your computer and follow the instructions in the recovery wizard.

Manual registry repair

If the above manipulations did not help and Windows is unclear why, but does not start, you can try to manually restore the registry from a backup copy. A copy of the Windows 7 registry is automatically created every 10 days and saved in the directory C:WindowsSystem32configregback. To restore the system, you need to copy all 5 files from the above folder to the folder C:WindowsSystem32config, where the current registry files are located. It is better not to delete old files, but to rename them (as a last resort).

• From the list of options, select Command Prompt. Open it and run notepad with the command - you will need it to launch Windows Explorer.

• In the notepad window, go to the menu "File" and select the item from it "Open"

• Go to directory C:WindowsSystem32config. To see everything in this folder, change the file type from. txt on "all files".
• Files Default, Sam, Security, System And Software(without extension) - this is the current registry. Rename them to something - add at least an extension to them .old.

• Open the folder Regback with backup registry files and copy them one by one to the folder config.

• After you have copied everything, restart your computer. If Windows failed to load due to the fault of the registry, the problem will be solved.

The reboot button is at the bottom of the window "Recovery Options".

File recovery

Windows' own protected file recovery tool - utility sfc.exe, can be successfully launched in a recovery environment. Usually it is launched with the parameter /scannow- to automatically search and fix found problems. In the recovery environment, you will also have to specify additional parameters: the location of the offline download directory and the offline Windows directory (for the recovery environment, the Windows folder and the drive where it is located are offline directories) These are the settings /offbootdir And /offwindir.

The complete command is written as shown in the picture:

IN offbootdir you need to specify the path to the system disk, and in offwindir- path to the Windows folder. Just remember that in the recovery environment, the partition letters may not match those that you see in Explorer when you normally boot Windows. The “correct” letters can be viewed by opening Explorer using a notepad.

If Windows 7 still won't start for some reason, you may have to manually restore your boot files, as well as rewrite your hard drive's Master Boot Record (MBR) and the system partition's boot code. Windows' own tools will also help you with this.

To recreate the boot files, open a command prompt and run the following command: bcdboot.exe C:Windows. Don't confuse the partition letter.

To overwrite the MBR and VBR (partition boot code), run the following commands: bootrec/fixmbr And bootrec/fixboot.

After that, check the download.

The operating system is a very complex software and, due to certain factors, it may work with malfunctions and errors. In some cases, the OS may stop loading altogether. We’ll talk about what problems contribute to this and how to get rid of them in this article.

Several reasons can lead to the inability to start Windows XP, from errors in the system itself to a malfunction of the boot media. Most problems can be solved directly on the computer on which they occurred, but some failures require using another PC.

Reason 1: Software or Drivers

Symptoms of this problem include the ability to boot Windows only in Safe Mode. In this case, during startup, a screen for selecting boot options appears or you have to call it manually using the key F8.

This behavior of the system tells us that in normal mode it is prevented from loading by some software or driver that you installed yourself or received by automatically updating programs or the OS. In “Safe Mode,” only those services and drivers are started that are minimally necessary for servicing and displaying images on the screen. Therefore, if you have such a situation, then the software is to blame.

In most cases, Windows creates a restore point when installing important updates or software that has access to system files or registry keys. “Safe Mode” allows us to use the system recovery tool. This action will roll back the OS to the state it was in before installing the problematic program.

Reason 2: equipment

If the reason for the operating system not loading lies in problems with the hardware, and specifically, with the hard drive on which the boot sector is located, then we see various kinds of messages on a black screen. The most common one is this:

In addition, we can get a cyclic reboot, during which a boot screen with the Windows XP logo appears (or does not appear), and then a reboot occurs. And so on ad infinitum until we turn off the machine. These symptoms indicate that a critical error has occurred, called a “blue screen of death” or BSOD. We do not see this screen, since by default, when such an error occurs, the system should restart.

In order to stop the process and see the BSOD, you need to perform the following settings:

Now we can see an error that prevents us from starting Windows. Problems with the hard drive are indicated by a BSOD with the code 0x000000ED.

In the first case, with a black screen and a message, first of all you should pay attention to whether all the cables and power cables are connected correctly, whether they are so bent that they could simply become unusable. Next, you need to check the cable that comes from the power supply, try connecting another, similar one.

Perhaps the power supply line that supplies power to the hard drive has failed. Connect another unit to the computer and check its functionality. If the situation repeats, then there is a problem with the hard drive.

If previous actions did not bring results, then the reason lies in software or physical damage to hard sectors. A specialized program can help you check and fix “bad things”. To use it you will have to use a second computer.

Reason 3: a special case with a flash drive

This reason is not very obvious, but can also cause problems loading Windows. A flash drive connected to the system, especially a large one, can be regarded by the operating system as additional disk space for storing some information. In this case, a hidden folder may be written to the flash drive "System Volume Information"(information about the system volume).

There have been cases when, when the drive was disconnected from a non-working PC, the system refused to boot, apparently not finding any data. If you have a similar situation, then insert the USB flash drive back into the same port and boot into Windows.

Also, disconnecting the flash drive may cause a failure in the boot order in the BIOS. The CD-ROM may be placed in first place, and the boot disk may be removed from the list altogether. In this case, go to the BIOS and change the order, or press the key when booting F12 or another that opens a list of drives. The purpose of the keys can be found out by carefully reading the manual for your motherboard.

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 . 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, 10 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. Causes:

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 components of the PC. 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 of 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 this 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.

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.

Solution to 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 loading Windows OS, 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? 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 instruction:

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.

Summary. 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, whether 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 disc does not help to roll back the OS to its original state or restore point, create or a new disk for restoring or installing 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 me 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 (it’s just 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, then I am asked to select Windows 7 OS 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 to enter explorer.exe.

Answer. If, when you try to boot Windows 7, a black screen and the cursor continues to appear, no matter which 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). 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 many hours troubleshooting. Sooner or later, any Windows OS develops problems.

Black screen when loading Windows 10. This happened after installing drivers from driverpack. After the system starts, a black screen is displayed, with a cursor visible, and sounds from programs that were opened in the browser (VK). Doesn't respond to anything, rebooting didn't help, and won't enter safe mode either.

Answer. You can use a Windows 10 boot disk or flash drive, select recovery mode and select a rollback point before installing the drivers. The black screen will disappear after loading Windows 10. You can enter Windows safe mode through the Windows installation disk; other OS boot modes are also available there.

If you can insert another video card into the system board, you can try it in the system and remove the drivers manually. Then change the video card to the old one - it should work.

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, and then turned off the virtual machine. When I tried to start 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.

The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then the operating system (OS) itself does not load, then naturally you need to dig towards the same OS.

And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.

A few recommendations on what to do if your computer won’t boot!

For the first case (when the computer turns on, but the OS itself does not boot).

Here, as a rule, there is a problem with system files, either they are damaged or completely lost. Try the tips below, all tips are for Windows XP:

1. Use the “Load last known known configuration (with working parameters)” option. You can use it as follows: after turning on the computer, press the F8 key, a window will appear, and in it select the above-mentioned menu item.
2. Enter safe mode and try to restore the computer to its previous state. To do this, when booting the computer, press the F8 key (as in the previous paragraph), select “Safe Mode”, if the system boots, go to the following path: Start -> All Programs -> Accessories -> System Tools -> System Restore. And following the wizard's prompts, try to restore an earlier working system.
3. If the previous methods did not help, then I suggest you familiarize yourself with another option. This option will return your computer to working order with a 99% probability. What do we have to do? You just need to update the old system. To do this, you will need a boot disk with Windows XP. Insert the disc into the DVD-ROM, reboot, it should boot from the CD, for this you need to set the appropriate item in the BIOS, or you can call up the boot option menu with the F12 key when booting the PC and select boot from CD/DVD-ROM, but This method may not be suitable for everyone.
   After booting from the CD, select "Install Windows XP" following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. This way, the Windows installer will update the existing copy. Wait until it finishes and try to boot normally.

For the second case (when the computer does not turn on at all).

In fact, there can be a lot of reasons for this, and it can sometimes be very difficult to help in absentia in this case. And, as a rule, the reason is a malfunction of some device (motherboard, power supply, RAM, etc.). At home, especially for an inexperienced user, there is simply no way to check the functionality of a device by replacing it with a known working one. But there is a way out, although not 100%.

First, try resetting the BIOS. To do this, you need to remove the battery for a few minutes. Or close the jumper contacts to reset the BIOS. Look for a jumper next to the battery labeled Clear CMOS (possible designations: CCMOS, CL_CMOS, Clear RTC, CRTC, CLRTC, CL_RTC). If it doesn't help, read on.

Second. It is necessary to disconnect ALL devices on the computer, leaving only the motherboard connected. That is, we take out the video card, all RAM slots, disconnect the hard drive and DVD-ROM from the power supply, if there are additional devices (internal modem, sound card, etc.) we take them out, leaving only the motherboard connected to the power supply.

And now we try to turn on the computer, if it turns on, then the problem is in one of the disabled devices. Turn off the computer and try ALTERNATELY connect devices, checking the computer for functionality. First, connect the most important devices (video card, hard drive, RAM), and then the secondary ones.

Thus, if, when installing a device, the computer stops turning on, you can independently determine the faulty device. If the computer does not turn on with one motherboard, then the problem is either with the motherboard itself or with the power supply.
