Why won't the operating system start? Consequences of physical impact. I. There is no image on the screen - neither the BIOS screen nor the operating system boot screen

You came home from school or work, decided to check new messages in your email inbox and social networks, turned on your computer with the latest version of the Windows operating system installed on it, but for some reason the OS refused to start normally. What to do, if Windows 7 won't load?

There may be a lot of reasons why Windows 7 won't load., ranging from problems with installed software to hardware malfunction. Usually, if any of the computer parts are faulty, this can be heard during the initial testing of the computer components.

Surely, when you booted your computer, you heard a short beep coming not from the speakers, but from the built-in speaker in the system unit. This signal means that all computer components are working properly. If there is no signal, or if the signal is long or there are several of them, this indicates a malfunction of one of the components. That’s why Windows 7 won’t boot. You can read about what exactly these or other signals mean during boot.

But what to do if, judging by the signal, everything is fine with the “stuffing” of the computer, but the operating system still does not boot? If you have two hard drives, the boot order in the BIOS may be out of order: The first disk in the boot queue is not the one on which the system is installed. Naturally, the system cannot boot. To check this guess, you need to check the boot queue when you boot the computer (how to do this should be written in the instructions for your motherboard) and, if necessary, change it.

If the desired disk is first in the boot queue, remember Have you installed any new programs or connected new devices?. Perhaps this is where the problem lies (especially if the operating system loaded normally before, but crashed immediately after installation). What to do in this case?

Try again the next time you boot your computer. If you succeed, first check and remove all unnecessary programs from there. If you recently installed a program or piece of hardware and think it might be the problem, try uninstalling the program in Safe Mode or disabling the hardware and uninstalling the associated driver. It also wouldn’t hurt to use one of the antivirus utilities to scan your computer for viruses in safe mode.

If Windows 7 does not boot even in safe mode, try to find an installation disk with the operating system - it will be useful to you. Most likely, the problem is a damaged MBR (Master Boot Record), the installation disk will help restore the MBR and, accordingly, normal loading of the operating system.

Insert the Windows 7 installation disk or system recovery disk into the drive and boot from disk(usually to boot from disk you need to press a certain key at boot or set the boot priority in the BIOS). If you are prompted to select a language when booting from a disk, do so, and then select recovery from the list of suggested options.

You will have to wait for some time for the computer to collect information about the installed systems and offer you a list of possible systems to restore. You need to select the appropriate Windows installation. You may be prompted to automatically fix your system. Why not try it - it might help. If you don’t want to try automatic correction, you just need to select “No”.

The next step will be the system recovery settings window. Here you can start with the Startup Repair option - restoring startup in automatic mode. It is also possible to restore the MBR manually. To do this, select command line mode and enter the following commands at the command prompt:

  • bootrec.exe /fixmbr
  • bootrec.exe /fixboot

The first command will restore the MBR (in some cases this is quite enough), the second - boot sector of the system hard disk partition and boot configuration data. After completing the recovery, restart the computer without the boot disk in the drive.

As you can see, there are several reasons why Windows 7 does not load, so the ways to solve this problem may be different. In advanced cases, it may be necessary to reinstall the system, but Usually it is possible to solve the problem in other ways.

Hello, dear readers, Denis Trishkin 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 steps. 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.

Greetings to all. Typically, if you have problems starting the operating system or the lights turn off during operation, a list of possible startups appears when you next boot the system.

In order not to mislead you and teach you some nuances, I will share some very useful tips. So, if the system did not boot but provided a boot choice, then I recommend selecting the following option - Last Known Good Configuration or loading the last good configuration.

This start option cancels any changes made to the registry key CurrentControlSet which directly caused the problem.

This registry key determines the values ​​of hardware parameters and all drivers installed on the system. Function loading last known known configuration will replace the contents of the above registry key with the data stored in the backup copy that was used during the last successful startup of Windows.

Reboot the computer. After the sound signal, press the F8 key and hold it until the operating system start selection menu appears. From the list of launch options that appears, select and activate it by pressing the key "Enter".

Remember, you are given one single attempt to restore the system's last known known configuration.

In general, if you were unable to restore the system after starting the OS from the mode, then this means only one thing - the backup copy is damaged. In this case, this recovery method will not help us.

1 Recovery Console

This method involves using the utility "recovery console". The more complex the problem of loading the operating system, the more serious the approach to solving it should be. The boot CD with the installation system usually contains a very useful utility - "Recovery Console"

To autorun a boot CD with Windows OS, place it in the DVD-CD drive and restart the computer. As soon as the computer reboots and the drive begins to read data from the disk, you will see the Setup and Installation Wizard dialog box.

This will happen if you have boot priority in the BIOS settings "Boot first device" You put "DVD/CD-ROM". I wrote about this in more detail in the article -. Once the download begins, follow all instructions that appear on the screen.

The program will provide you with a selection of basic files to run the installation program. The installation wizard greets you with the phrase "Welcome To Setup". Now all you have to do is press the key "R" which facilitates the opening of the recovery console.

Now the Recovery Console dialog box has opened in front of you. Here we will see a folder with files and also a request to select the operating system with which you plan to start working.

Next, you have to press the key with the number corresponding to the operating system number, then the program will ask for the administrator password, if any. Well, now you have full access to the command line.

I wrote more about how to work with the recovery console in the article -

3 Fixing damage to the Boot.ini boot file

At the initial stage of Windows OS startup, the Ntldr program accesses the boot file Boot.ini. As a result, the program determines the location of system files and available options to continue booting.

This is precisely why, in case of damage to the boot file Boot.ini, the operating system cannot continue or even start booting correctly.

In the event that Windows OS does not boot and the reason for this is a damaged file Boot.ini then the recovery console toolkit will help you - Bootcfg.

To start it Bootcfg you will, of course, need to start the system from a Windows XP boot disk. To run the command Bootcfg, you need to enter into the command line of the management console: Bootcfg /parameter

Where /parameter- this is one of the functions that I will tell you about now.

Add– scans the hard drive for all installed operating systems. In addition, it adds the identifiers of new operating systems to the boot file Boot.ini.

Scan- scans the hard drive for all installed operating systems.

List– displays a list of records in the file Boot.ini.

Default– displays the identifier of the operating system that is being run during startup

Rebuild– completely restores the Boot.ini boot file. The user is given the opportunity to control every step.

Redirect– in administration mode, this function allows you to redirect download operations to another specially designated port. It has several subparameters, or rather two: | ./Disableredirect – Disables redirection.

It is worth noting that in Windows Xp and Windows 7 boot.ini is formed differently. I wrote several articles on the topic of boot.ini for XP and 7:

4 Repairing a defective Master Boot Record

The master boot record uses the first sector of the hard drive and carries out the boot procedure for Windows XP. The entry contains a table of all available hard drive partitions and a small program "primary loader" The primary bootloader, in turn, is responsible for placing the active or boot sectors in the partition table.

Once placed in the table, the boot sector begins to start the operating system. If suddenly the boot record is damaged, the active sector will not be able to start the system.

In order to fix this problem, the recovery console provides the Fixmbr program. Boot from the installation disk and activate the recovery console.

In order to run the Fixmbr command, you need to enter the following into the command line of the management console: Fixmbr

Where - the compound name of the disk for which there is a need to create a new master boot record. The qualified name for the main boot drive C:\ will look like this: \Device\HardDisk0

5 Restoring a damaged HDD boot sector

The boot sector is a small section of the hard drive dedicated to storing data in the operating system, having an NTFS or FAT32 file system, and it is also a fairly small program that helps in the process of loading the operating system.

If the system refuses to start precisely because the boot sector is inoperative, the recovery console tool can help you FixBoot. To do this, you need to load the installation disk and go to the recovery console menu.

In general, I have already indicated above how to do this. In order to run this program, you will need to enter the following in the command line of the management console: Fixboot:

Where- the drive letter that requires creating a new boot partition.

6 Quick reinstallation of Windows

In the event that you cannot get the system to start and you do not have a backup copy, you can perform a Quick Reinstallation of Windows.

This procedure involves reinstalling the operating system in the same directory (similar to updating an old version of the system to a newer one) and can fix almost any Windows boot problem.

Place the boot disk into the DVD/CD drive, then restart the computer. Once the disk is recognized and reading begins, you can begin the installation procedure. During installation, a license agreement will appear.

In order to agree to the terms of the agreement, press the F8 key. Next, the program will scan all installed versions of Windows. As soon as at least one of the versions is found, the installation screen will appear.

In order to start restoring the version of the system you need, you need to click "R", and to start the installation "Esc". The system recovery procedures will start. The installation wizard will now begin checking the disks for functionality, and then begin a quick reinstallation.

Remember, after reinstalling or recovering a damaged installation, all updates will have to be reinstalled again.

7 How to cancel automatic reboot

As a rule, if an error occurs during stable operation of the system, the operating system automatically reboots.

When an error occurs directly at system startup, a cycle of endless reboots occurs. In this case, you need to disable the function of automatically rebooting the system upon failure.

At the beginning of the operating system startup or after POST, press the F8 key, which will open a menu in front of you "Extra options".

Next you need to select the item "Disable automatic reboot on system failure" and activate it by pressing the key "Enter". Now, when Windows XP starts up, it will display an error message, the essence of which will tell us about the malfunction.

Restoring the Windows operating system from a backup copy.
If none of the system recovery methods helped you, then there is a chance to restore the operating system using a backup copy (if you have one).

The recovery algorithm completely depends on the program you are using to perform the backup, which provides you with all the necessary instructions.

Conclusion

There can be many recovery methods and reasons why Windows does not boot. The main thing is that the system is mostly recoverable and you don’t have to perform. That's all. I wish you success in dealing with the problem.

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 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 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, which can be used to 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 System Restore mode to enter. 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.

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 you are 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) 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.

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). It doesn’t respond to anything, rebooting didn’t help, and it doesn’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.

Many PC users work with Microsoft products. For example, with the corresponding operating systems. They are called Windows (English - “window”). Every year new operating systems are being developed and released. Today, users can enjoy Windows 8 and Windows 10. However, this is not the only software for the computer. There is another very successful Microsoft product. We are talking about Windows 7. The majority of users prefer to work with this software. It has a pleasant and understandable interface, and also copes with its tasks properly. But there are exceptions. For example, there are often cases in which Windows 7 does not load. What should I do? What should the user do to bring the computer back to life? Below we will look at the reasons for failures when loading Windows, and also try to figure out how to troubleshoot the problems.

Main reasons

Windows 7 won't boot? This operating system is considered one of the most successful from Microsoft. Many users prefer it. But the operating system is very vulnerable software. Therefore, errors in its work cannot be ruled out.

Most often, problems loading the operating system are caused by:

  • system failures;
  • PC virus infection;
  • "cluttered" computer;
  • hardware damage;
  • incorrect software installation;
  • conflicting components connected to the computer.

In fact, the situation can be corrected in different ways. It all depends on the problem. If Windows 7 does not boot, the user will have to discover the reason for this behavior (fortunately, this is often easy to do) and then resolve the conflict. And only occasionally do you have to agree to extreme measures.

Download steps

First, let's try to understand exactly how the OS loads on a computer. This way the user can find out at what stage the problems occurred. This will definitely help in the future.

  1. OSLoader. The stage that begins with starting the BIOS. That is, immediately after turning on the computer. First, the BIOS code is executed, then the main drivers are connected. They are needed to read data from the hard drive. After this, the Windows kernel is connected, as well as the registry branch.
  2. MainPathBoot. Largest loading step. It connects all the necessary components and drivers to the operating system. Settings, options, some applications and all built-in services are loaded during MainPathBoot. This stage is displayed on the screen as a blue background with “Windows 7” written on it.
  3. PostBoot. Activated when loading the desktop. This stage completes the download of Windows 7 and connects the remaining applications and programs.

That's all. In fact, everything is not as difficult to understand as it seems. However, you will have to figure out what to do if Windows 7 does not boot. Problems are usually detected at the MainPathBoot stage. But they also happen with PostBoot. At the OSLoader stage, errors with loading the operating system almost never occur. This step only takes a few seconds.

PC Damage

Windows 7 won't load? It is often difficult to understand what exactly happened - a hardware failure or system problems. After all, the computer can behave the same in both cases.

So, if the user thinks that some components on his computer are damaged, they will need to be replaced. Ideally, take a closer look at the behavior of the operating system. Very often, Microsoft tells the user what the problem is. For example, by displaying the “blue screen of death”. But more on that later.

After replacing the faulty parts, the error loading Windows should disappear. The following scenarios may indicate such a problem:

the same driver constantly fails on the computer;

  • "blue screens of death" occur;
  • you can hear the sounds of the operating system on the computer, but there is no picture on the screen;
  • sudden freezing of the Windows boot process;
  • turning off the computer while processing the OS boot stages.

Which of these phenomena indicate what? This will be discussed below.

Signals - pointers

Did you encounter an error loading Windows 7? Often failures are associated with hardware damage. But what should you check first? It all depends on the situation.

Previously, we provided several indicators of computer hardware damage. But what exactly do they point to? Let's try to figure this out.

So, users can focus on the following data:

  • driver errors - a malfunction of the device for which one or another software package is installed;
  • “blue screen of death” - problems with RAM (but there are exceptions);
  • no picture on the screen - damage to the video card;
  • stop OS loading - ;
  • power cut while the PC is booting - a problem with the power supply.

Can the listed phenomena occur when some computer components conflict? Yes. For example, if after installing a new video card the OS does not show a picture on the monitor, you should either replace the rest of the hardware or return the old video card. Fortunately, diagnosing such phenomena is easier than other problems.

Download files

Windows 7 won't boot normally? Often, users say that they encounter black screens in the early stages of loading. They say "Bootmgr is missing". Next, you are asked to press Ctrl + Alt + Del to reboot the OS. Sometimes the user may encounter a regular black screen with no text. The cursor moves across the monitor when you move the mouse, but nothing more.

This error indicates that the boot file was corrupted while the computer was running. Bootmgr is a bootloader for Windows 7 and Windows 8. It is initially hidden from users. Removing it when formatting the hard drive is problematic. Often the cause of this error is viruses.

What to do in this case? Installing Windows 7 on your computer from scratch will help. This is the simplest solution. You can try to restore the operating system, but if this technique does not help, you will have to act decisively and radically.

Registers

Windows 7 won't load? A black screen, as we have already said, either indicates problems with the video card, or highlights failures of the Windows bootloader. Sometimes when you start your PC, the system registry is not read and loaded. This is an extremely important element.

As a rule, an error is easily identified - a corresponding warning appears on the computer screen. In addition, correcting the situation will be easier than it seems. The computer will launch the recovery wizard. By following his instructions, the user will be able to fix the problem. Not always, but often this technique helps.

Recovery Wizard

But the user will not always be able to use the automatic operating system recovery wizard. Sometimes you have to call him yourself. In addition, if Windows 7 does not boot, everyone has the right to use a set of OS recovery tools.

To launch the corresponding menu, you must:

  1. To restart a computer.
  2. At the PC boot stage, press "F8" several times.
  3. Select "Troubleshoot your computer."
  4. Enter the access password.
  5. Click on "Startup Repair".
  6. After completing the operation, reboot the PC.

Using the menu called up, you can perform a system rollback. To do this, just select There is nothing incomprehensible or difficult about this.

Safe mode

Sometimes Windows 7 does not boot in normal mode. In this case, you will have to restore the OS. It is advisable to do this using Windows 7 Secure Boot. In addition, this mode helps restore drivers and clean the operating system.

To use Secure Boot you will need:

  1. Turn on the computer.
  2. Click on "F8".
  3. Select "Safe Mode".

You can wait for the operating system to load. Shortcuts will appear on the screen on a black background. To restore the OS, just go to “Start” - “All Programs” - “Accessories” - “System Tools” - “Recovery”.

After a secure boot, the user will be able to use all Windows services. For example, the command line. It often helps get rid of some

"Blue Death"

Sometimes users are bothered by a blue screen when loading Windows 7. It's called the "blue screen of death". As we have already said, most often such an error occurs due to problems with RAM.

A blue background appears on the monitor display. It has specific error information written in white font. The user does not need most of the information. Just look at the type of error, as well as the “Technical Information” section. With their help you can understand what's going on.

Errors with the hard drive and/or its controller can be indicated by errors like:

  • stack_inpage_error;
  • data_inpage_error;
  • inaccessible_boot_device;
  • mode_exception_not_handled.

It is advisable to have a BIOS error reference book on hand. It contains a complete list of Blue Screen of Death errors. With its help, everyone will understand exactly what the problem is with downloading Windows 7. There is no need to install a new operating system. But how to bring your idea to life?

Reset BIOS

Russian Windows 7 won't load? A similar problem occurs when working with hacked software. By reinstalling it, the error will disappear.

As we have already said, the Blue Screen of Death indicates corruption in the BIOS. Resetting the settings will help correct the situation. You can do this:

  1. Get to the motherboard and press the special jumper.
  2. Remove the coin cell battery and insert it back. The corresponding element is located on the motherboard. It is recommended to completely replace the battery on your PC if there are BIOS problems.
  3. Turn on the computer, press the BIOS button ("F2", "F4", "Del" and so on - it all depends on the motherboard). Go to Exit and set the pointer to Load Setup Defaults, click on the "Enter" button. Save changes.

Ready! Now the "screen of death" will no longer bother the user. But what to do if the operating system still does not boot.

File recovery

In some cases, Windows 7 will not load due to damaged system files. They can be restored manually. This technique works if automatic recovery does not produce results.

To perform a manual operation, the user must:

  1. Launch the command line in Windows 7. It is advisable to do this in safe mode.
  2. Write: sfc/scannow /offbootdir=c:\ /offwindir=c:\Windows.
  3. Click on "Enter".

You can wait for the computer to be scanned and the boot files to be restored. The operation usually takes a few minutes.

Re-creating a section

Is Windows 7 loading slowly? What to do if in the end this operating system does not start?

Didn't all the tips listed above help? Then you can try to recreate the boot sector. It is also recommended to rewrite the boot code.

This is done like this:

  1. Open a command prompt in safe mode on your computer.
  2. First enter bcdboot.exe C:\Windows and perform the operation.
  3. Write bootrec/fixnbr and bootrec/fixboot.
  4. Execute requests.
  5. To restart a computer.

Ready! Now is the time to check the loading of the operating system. It is possible that the problem will go away.

Slow work

If the operating system is working in principle, the user can be offered the following acceleration methods:

  • disable startup programs;
  • scan the OS for viruses and remove all malicious files;
  • launch CCleaner and clean the PC registry;
  • clean the operating system of files and programs.

All this really helps. If the techniques are not effective, you will have to agree to reinstall Windows 7. Usually the idea requires an installation disk. In the BIOS, you need to set the hard drive to first place in the Boot section, and then, following the instructions on the screen, complete the installation.
