Most users, when closely interacting with a computer, have experienced a sudden shutdown of the system, accompanied by a blue screen with incomprehensible information. This so-called "BSOD", and today we will talk about what it is and how to deal with it.

BSOD is an acronym that literally means " blue screen of death". It was impossible to say more precisely, because after the appearance of such a screen, further work without a reboot is impossible. In addition, this behavior of the system indicates rather serious problems in the software or hardware PC. BSODs can occur both when the computer boots up and during its operation.

There are a lot of options for errors registered on blue screens, and we will not analyze each separately here. It is enough to know that the causes that cause them can be divided into software and hardware. The former include failures in drivers or other programs closely related to the operating system, and the latter include problems with RAM and hard drives. Wrong BIOS settings, for example, incorrect voltages or frequencies during overclocking can also cause BSOD.

Most of the special cases are described on the site bsodstop.ru. To work with this resource, you need to understand the structure of the data provided by the system.

The most important is the hexadecimal error code shown in the screenshot. This information is to be found on the website.

In the event that the system automatically reboots, and there is no way to read the information, we perform the following actions:

Now, when a BSOD appears, a reboot can only be performed in manual mode. If you cannot access the system (an error occurs during boot), you can set the same parameters in boot menu. To do this, when starting the PC, press the key F8 or F1, and then F8, or Fn+F8. In the menu, you need to choose to disable automatic reboot during a crash.

Reason 1: Drivers and programs

Drivers are main reason occurrence of blue screens. These can be both firmware for hardware, and files embedded in the system by some software. If the BSOD occurs after installation software, then there is only one way out - to perform a "rollback" to the previous state of the system.

If there is no access to the system, then you must use the installation or boot media with the OS version recorded on it, which is on this moment installed on PC.

Carefully monitor the behavior of the system after installing any programs and drivers and create restore points manually. This will help to correctly identify the causes of errors and eliminate them. Timely update operating system and the same drivers can also get rid of a lot of problems.

Reason 2: "Iron"

The hardware issues causing the BSOD are as follows:

  • Flaw free space on the system drive or partition

    You need to check how much storage space is writable. This is done by right-clicking on the corresponding disk (partition) and going to properties.

    If there is little space, that is, less than 10%, it is necessary to remove unnecessary data, unused programs and clean the system of garbage.

  • New Devices

    If a blue screen occurs after connecting new components to the motherboard, then you should try to update their drivers (see above). In case of failure, you will have to refuse to use the device due to its possible malfunction or inconsistency in characteristics.

  • Mistakes and bad sectors on hard drive

    To identify this problem, you should check all drives for problems and fix them if possible.

  • RAM

    Faulty "RAM" strips are very often the cause of failures. You can identify "bad" modules using the program.

  • Overheat

    BSOD can also be caused by overheating of components - processor, video card or components motherboard. To eliminate this problem, it is necessary to correctly determine the temperature of the "iron" and take steps to normalize it.

Reason 4: BIOS

Incorrect motherboard firmware (BIOS) settings can lead to a critical system error and a blue screen. The most correct solution in this situation would be to reset the parameters to default.

Reason 3: Viruses and antiviruses

Viruses that have entered your computer can block some important files, including system files, and also prevent drivers from working properly. You can identify and eliminate "pests" using free scanners.

If a virus attack has closed access to the system, then this operation will help, recorded on removable media. Scanning in this case is performed without loading the operating system.

Antivirus programs may also behave inappropriately. They often block "suspicious" system files, which are responsible for the normal operation of services, drivers and, as a result, hardware components. You can get rid of the problem by disabling or removing the antivirus.

Blue Screen Features in Windows 10

Due to the fact that Microsoft developers are trying to limit user interaction with system resources, the information content of BSODs in Windows 10 has decreased significantly. Now we can only read the name of the error, but not its code and the names of the files associated with it. However, the system itself has a tool for identifying and eliminating the causes of blue screens.

  1. Let's go to "Control Panel" by calling the string "Run" keyboard shortcut Win+R and entering the command

  2. Switch to display mode Small Icons» and go to the applet "Center for Security and Service".

  3. Next follow the link "Troubleshooting".

  4. Open the block containing all categories.

  5. Choose an item "Blue screen".

  6. If you want to fix the problem right away, then click "Further" and follow the prompts "Masters".

  7. In the same case, if you need to get information about the error, click on the link "Additionally".

  8. In the next window, uncheck the box next to the inscription "Automatically apply fixes" and go to the search.

This tool will help you get detailed information about the BSOD and take appropriate action.

Conclusion

As you can see, fixing BSODs can be quite difficult and time consuming. In order to avoid the appearance of critical errors, update drivers and the system in a timely manner, do not use dubious resources to download programs, do not allow components to overheat, and read the information on specialized sites before overclocking.

Death". This is the common colloquial name for messages about critical failures in operating systems running MS Windows. Their appearance is due to the occurrence of fatal errors that occur when executing the code of any drivers or. As a result, the only possible action for the user is to send the computer to reboot without the ability to save current data.

Usually, system settings by default are set in such a way that in case of a critical failure occurs automatically. The operating system then creates a log entry that describes the error that occurred.

Information that you can use when you see the "blue screen of death" - errors and their codes, specifications, as well as some tips for troubleshooting these failures. Usually, the message and recommendations are in a standard form, but the technical information changes according to the type of error that occurred and consists of:

The code of the failure that occurred and its symbolic name;
- parameters explaining the error, intended for debugging software;
- addresses of the place of failure;
- the name of the driver in which the problem occurred.

What to do if the "blue screen of death" did appear? As we said above, the system settings assume an automatic reboot in the event of a BSoD. However, she will continue to do this until the error is completely eliminated. But we recommend disabling this option so that the user can record the fault code and find out the reason that caused it. To do this, open the "Control Panel", go to the "System" item, in which on the left side there will be a link " Extra options In the properties that open, on the Advanced tab, click the Settings button in the Startup and Recovery block, then in the System Failure block, uncheck the Perform an automatic restart checkbox. Save the changes.

If you have a "blue screen of death" in front of you, write down the error code, it will help to find out the cause of the malfunction. After that, send the computer to reboot using the "Reset" button. When the system boots, press F8. From the menu that appears, select "Load Last Known Good Configuration".

If this operation does not work, restart the computer again, press F8 again and enter. If the boot is successful, try performing a system restore. If this fails, find your error code in a special table that contains a list of faults that cause the "blue screen of death" and try to find out its cause. After fixing it, try to restore the system again using safe mode.

If the problem that causes the BSoD is software and not hardware in nature, it will be enough to restore the system to fix it, or even better, reinstall it, and given error will not appear again.

In order to make sure that the hardware of your computer is in order, you need to test its hardware. You can check the hard drive using the MHDD utility, which runs from a 3.5 "floppy disk under MS-DOS, and to check the status random access memory you can use memtest86+, which also runs from floppy.

By the way, the "blue screen of death" of Windows 7 will soon cease to be relevant - this is the last OS where it will be present in its pure form. However, do not deceive yourself, because this does not mean that Microsoft will write the perfect OS. The fact is that BSoD will simply be replaced by KSoD ("black Screen of Death"), and henceforth you will have to deal with death", that's all.

Finally, we note that reinstalling the OS is only a short-term solution to the BSoD problem, and if the cause of its occurrence has not been clarified, there is a high probability that it will reappear in the near future.

While loading or running the Windows operating system, an error or glitch may occur that results in a blue screen with white text.

And in this case, you can only reboot the computer, since other actions will not be available. It is for this reason that this very screen is called the "blue screen of death" (BSOD).

What it is

The appearance of the blue screen of death means that the operating system has crashed. The reason for such a failure can be very diverse. A similar problem can happen to anyone, so you need to know what to do if a BSOD appears.

There is no need to worry and overly fuss. It is recommended to overload system unit, and all unsaved data will be lost.

Often, when you reboot, the problem disappears, but it is still useful to know the reason why the failure occurs. To do this, you need to parse some string located on the blue screen of death, which contains an error check string and verification code errors to find information on them on the Internet.

System Setup

In order to be able to diagnose and fix the problem when a critical failure occurs in the operating system, you must configure the operating system in a special way.

For this you need:

  • check that in Windows settings memory dump saving is enabled;
  • guided by the required size of the memory dump file, you need to check whether there is enough free space on the system disk for its location;
  • disable rebooting the operating system after a BSOD.

Windows XP

To configure Windows operating system settingsXPnecessary:

  • enable debug information logging, namely go to:

  • Specify how much debugging information should be logged if a crash occurs.

Windows Vista/7

Windows Vista/7 settings are similar Windows settings xp.

Windows 8

In Windows, you can adjust settings so that the operating system does not automatically reboot. In Windows 8, this requires:


Deciphering information in the Blue Screen of Death

Each critical error is accompanied by a detailed description and an eight-digit error code. When you first encounter a BSOD, the information displayed on it seems to be a random sequence of characters, but in fact, the description and error code will help to a large extent to reveal what caused the failure and what this error means.

The top of the monitor contains a description of the error, consisting of words stuck together in capital letters and separated by underscores.

Immediately after the description of the error, some troubleshooting tips are displayed. They are followed by a technical information section with an eight-digit hexadecimal error code.

Depending on the nature of the error, the code is usually completed with four auxiliary values ​​enclosed in parentheses.

If the error that caused the BSOD is directly related to some file, this section displays its name.

Reasons for the appearance

There are many reasons for the blue screen of death.

All reasons for the appearanceBSODon Windows can be broken down into three components:

  • equipment;
  • drivers;
  • programs.

Video: Blue screen in Windows

Equipment

One of the most common causes, which can cause BSOD, in this category are problems with RAM. It needs to be tested.

Also, failures in the functioning of the storage system are not uncommon. In this case, it is worth diagnosing the hard drive and checking for free space on it.

Less commonly, the cause of the blue screen of death is a problem with the video adapter and processor. It is important to test this equipment using specialized utilities.

In addition to the main components of the computer, problems can arise with additional cards that expand functionality system block. You can find out the source of the problem by removing additional nodes and testing the computer for several days without them. If the computer functions normally without failures, then the problem is solved.

You can also try plugging the board into a different motherboard slot. After testing all the components separately, you should test the operation of the entire system under load. If it fails under load, the problem is probably in the operation of the power supply. The way out is to replace the power supply with a more powerful one.

Drivers

There is an opinion that drivers are the source of 70% of BSOD cases. To treat the system, the driver must be reinstalled, after deleting it. If the problem is not solved, then you need to download the driver from the manufacturer's website and install it.

There are situations when it is not possible to find a fresh driver, in which case you can install an earlier version.

If replacing the driver does not help, then you should check the compatibility of the device with the operating system. If there is no compatibility, it is recommended to replace the hardware or reinstall the operating system.

ON

Software-related problems that have arisen are solved in a similar way. It is necessary to reinstall the existing one, or install the version downloaded from the developer's site.

The likely cause of a critical error may be the simultaneous installation of two or more anti-virus tools for one operating system.

Memory dump analysis

To analyze critical memory dumps, you can use one of the huge number of programs, for example, DumpChk, Kanalyze, WinDbg.

Consider the example of WinDbg (part of Debugging Tools for Windows) how can the analysis be carried out crash dumps memory.

The sequence of actions is as follows:

  • download current version programs from the developer's site;
  • install the program on the computer;
  • run the program;
  • go to the menu item “File –> Symbol File Path…”;
  • in the “Symbol Search Path” window, click “Browse…”;
  • in the window that appears, select the location of the Symbols directory. Then press “OK” twice, then select the menu “File –> Open Crash Dump…”;
  • in the "Open Crash Dump" window, select the path and click "Open";
  • in the "Workspace" window, set the "Don'taskagain" checkbox to "No";
  • the "Command Dump" window will be displayed with dump analysis;
  • analyze the memory dump in detail;
  • it is especially important to pay attention to the "Bugcheck Analysis" section, which displays possible reason failure;
  • to view complete information you need to click on the link "!analyze -v";
  • close the program;
  • apply the data obtained to eliminate the cause of the crash.

Fixing blue screen of death errors

The lion's share of blue screen of death errors is due to corruption of some system files or missing or incompatible drivers.

WhenBSODyou need to do the following:

Error codes

For faster and more effective “computer treatment”, you need to have an idea of ​​​​what error codes mean and how to fix the blue screen of death problem. Therefore, it is extremely important not to ignore the text that displays the BSOD. Most important information on the blue screen of death is the hexadecimal error code and its description.

The number of BSOD errors reaches several hundred. It is simply impossible to know or describe all error codes and how to resolve them. It is much easier and better to use specialized resources that contain detailed information about errors and describe the sequence of actions to solve the problem in the most efficient and safe way.

To do this, you just need to go to the appropriate resource, find the error with the required code, study the information about it and restore the operating system in accordance with the recommendations received.

The most common errors:

  • 0x00000001 - internal kernel error;
  • 0x0000000A - inaccessible memory address;
  • 0x0000001E - incorrect processor command;
  • 0x00000020 - driver error;
  • 0x0000002B - stack overflow;
  • 0x00000051 is a registry error.

AT individual cases the functioning of the Windows operating system may end with the appearance of a blue screen of death, which displays a certain sequence of characters.

The appearance of a BSOD indicates a critical error in the operation of the operating system. The way to resolve the failure depends on the system error code, which can be viewed at the bottom of the blue screen.

Good afternoon.

Although, probably, he is not so kind, since you are reading this article ... In general, the blue screen of death is not a pleasant pleasure, especially if you created a document for two hours, and autosave was turned off and you didn’t have time to save anything .. Here you can turn gray if this is a term paper and you need to take it the next day. In this article I want to talk about step by step recovery computer work, if you are tormented by a blue screen with enviable regularity ...

And so, let's go...

Probably, you need to start with the fact that if you see a "blue screen" - this means Windows has completed its work with critical mistake, i.e. there was a very serious failure. Sometimes, getting rid of it is quite difficult, and it only helps reinstalling Windows and drivers. But first, let's try to do without it!

Eliminate the blue screen of death

1) Set up your computer so that it does not restart during a blue screen.

By default, Windows, after the appearance of a blue screen, goes to reboot automatically without asking you. There is not always enough time to write down a mistake. Therefore, the first step is to make sure that Windows does not restart automatically. A little lower will show how to do this in Windows 7, 8.

Open the computer control panel and go to the "System and Security" section.

Here we are interested in boot and recovery options.

In the center of the window, under the heading "system failure" there is an item "perform automatic reboot". Uncheck this box so that the system does not reboot and gives you the opportunity to take a picture or write down the error number on paper.

2) Error code - the key to unraveling the error

Before you appeared the blue screen of death (by the way, in English it is called BSOD). You need to write down the error code.

Where is he? The screenshot below shows the line that will help establish the cause. In my case, an error like "0x0000004e". I write it down on a piece of paper and go looking for ...

I suggest using the site http://bsodstop.ru/ - there are all the most common error codes. Found mine, by the way. To solve it, I am recommended to identify the failed driver and replace it. The wish, of course, is good, but there are no recommendations on how to do it (we will consider it below) ... Thus, you can find out the reason, or at least come very close to it.

3) How can I find out the driver that caused the blue screen?

In order to determine which driver failed, you need the BlueScreenView utility.

It is quite simple to use it. After launch, it will automatically find and show the errors that were fixed by the system and reflected in the dump.

Below is a screenshot of the program. Above shows the errors when the blue screen occurred, date and time. Select the desired date and see not only the error code on the right, but also the name of the file that caused the error is shown at the bottom!

On this screenshot, the file "ati2dvag.dll" somehow did not suit Windows. Most likely, you need to install newer or older drivers on the video card and the error will disappear by itself.

Likewise, step by step, and you will be able to identify the error code and the file that is causing the crash. And then you can try to replace the drivers on your own and return the system to its previous stable operation.

What to do if nothing helps?

1. The first thing we try to do, when a blue screen appears, is to press some keys on the keyboard (at least that's what the computer itself recommends). 99% that nothing will work out for you and you will have to press the reset button. Well, if nothing else remains - click ...

2. I recommend testing the entire computer and RAM in particular. Very often a blue screen occurs because of it. By the way, wipe its contacts with a regular eraser, blow dust off the system unit, and clean everything. Perhaps due to poor contact of the RAM connectors with the slot where it is inserted and a failure occurred. Very often this procedure helps.

3. Pay attention to when the blue screen appeared. If you see him every six months or a year, does it make sense to look for reasons? If, however, he began to appear after each Windows boot- pay attention to the drivers, especially the ones you recently updated. Most often, problems arise due to drivers for the video card. Be sure to update them, or install a more stable version if this was the case.

4. If the computer issues a blue screen immediately at the time of Windows loading itself, and not immediately after it (as in step 2), then the system files of the OS itself were most likely corrupted. For recovery, you can even use standard system restore utilities for checkpoints.

5. Try to go to safe mode- perhaps from there you will be able to remove the failed driver and restore the system to working order. After that, the best option is to try to restore Windows system using the boot disk from which you installed it. To do this, start the installation, and during it, select not "install", but "restore" or "update" (depending on the OS version, there will be different wordings).

6. By the way, I personally noted that in newer operating systems, a blue screen occurs much less frequently. If your PC passes the specifications for installing Windows 7, 8 on it, install it. I think there will be fewer mistakes in general.

7. If none of the previously suggested helped you - I'm afraid only reinstalling the system will correct the situation (and then if there are no hardware problems). Before this operation, all the necessary data can be copied to USB flash drives (booted using a Live CD, not from your hard drive) and you can safely reinstall Windows.

BSoD or "Blue Screen of Death" in Windows can appear for various reasons. Starting from a failure in a separate program, ending with a breakdown of important equipment. If you saw BSoD only once, it's too early to sound the alarm. But if the failure is regular, then there are some problems with the computer. And you need to pay attention to the information that is shown in the error.

You quietly worked at the computer, and saw the "Blue Screen of Death" in Windows 7. What to do in this case? You don't have to restart your PC right away. Look at the error code. From it you will understand that it is “broken”. And you can eliminate the cause of the failure.

When the BSoD appears, pay attention to the sections:

  • "The problem seems to be caused". The file that caused the crash is listed there;
  • A little lower will be the name of the error;
  • "Technical Information". Technical information. The error number must be written after the word "STOP". For example, "0x0000007E" or "0xC0000135";
  • Next comes the name of the driver and the address of the error.

Reasons for the error

Remember what happened before the Blue Screen of Death arose. That way you can figure out what to do with it. For example, you connected a new device, installed a program, updated the system, or downloaded unlicensed drivers for Windows. If it was after this that problems began, then you found the culprit. You can also determine the cause by looking at the error codes.

Here's what's causing the crash:

  • Hardware malfunctions. The hard drive may be damaged, RAM, Network Card, video adapter;

The cause of the problem may be hard drive malfunction disk

  • Connected incompatible device or equipment. Let's say you decide to install new RAM boards or attach an external hard drive. And after that, Windows began to crash into BSoD;
  • Software conflict, in particular drivers;
  • Crashes in the BIOS or bad firmware;
  • Overheat;
  • Update Windows or individual services. Along with this, you can download great amount errors. Not even safe from them. licensed programs. If the BSoD appeared after a system update, just roll it back. And wait until the update is fixed and optimized;
  • Contact of wires and internal equipment. For example, the cable got into the cooler blades;
  • , which damaged important files;

  • User actions. Someone tried to "overclock" the computer. Or deleted system data.

Error codes

To understand how to get rid of the problem, you need to look at the error codes. The Blue Screen of Death provides the necessary information. But the list of such numbers is huge. After all, anything can break. And it is not clear what to do in this case. Here are the most common failures:

  • "0x0000000X", where "X" ("X") - numbers from 1 to 5. Relevant for Windows Server 2003 and Win XP with Service Pack SP Appears when installing some antiviruses. To fix everything, download the update "KB887742" from the Update Center or from the official Microsoft website;
  • "0x0000000A" and "0x0000000X", where "X" is a number from 6 to 9. The driver is damaged. Or there are incompatible programs/hardware;
  • "0x0000000X", where "X" can be numbers from 13 to 19. Codes mean that there is no communication with the memory board. Or the connection to the hard drive on which the swap partition is located is lost;
  • "0x0000001F" and "0x0000000X", where "X" are numbers from 20 to 23. Error while reading/writing information. Appears in FAT file systems. Damage may be the cause hard drive or severe data fragmentation. The Blue Screen of Death with this code also occurs due to incompatible antiviruses and firewalls;
  • "0x00000024". The same, but for the NTFS file system;
  • "0x0000000X", where "X" is a number from 28 to 35. Problem with drivers or RAM;
  • "0x0000000B", "0x0000000C", "0x0000000D". Related to sound card software bugs sound blaster live;
  • "0x00000051". Occurs when the system cannot read some registry entry. This happens when the system or equipment is damaged;
  • "0x00000057". Something is wrong with the network card;

Death screen example

  • "0x00000069". Incorrect installation system or misconfiguration;
  • "0x00000073". Damaged part of the registry. Or there is not enough free memory;
  • "0x0000007E". May appear when windows update. For some reason, the update caused a crash. To fix it, you need to roll back the system;
  • "0x0000008E". Breakdown of RAM. Or the RAM modules are not compatible with each other;
  • "0x000000FE". Critical failure in the USB controller;
  • "0x00000104". Problem with the video adapter driver or BIOS firmware;
  • "0x1000007E", "0x1000008E", or "0xC000009A". System Windows kernel not enough resources for stable operation. Free up RAM and local memory;
  • "0x80070570". System installed incorrectly. The problem may be in the installer itself;
  • "0xC0000135" and "0xC0000218". Damaged or missing important dynamic libraries. BSoD shows which object is not available;
  • "0xC0000221". Problem with driver or library;
  • "0xDEADDEAD". The user himself initiated an emergency stop of the system.

The list is quite long. It has hundreds of different rooms. You can enter the error code in the search engine to find out more information. Or look at it on the site "bsodstop.ru" ("BSoD: error description" tab). There are also instructions that describe what to do in each situation.

If the same failures occur with different objects (the codes are the same, but the file names are not), most likely the problem is not in the system, but in the hard drive. Back up your important data as soon as possible. If they end up in a damaged sector, it will be difficult to restore them.

View code if system reboots

How to find out the failure number if the computer restarts when a BSoD occurs? And you just don't have time to read the message.

Blue screen codes can be viewed in dumps. They are located in the Windows\Minidump system directory. To open these files, you need the BlueScreenView program. Find it on the Internet, install and open it. It will scan the dumps and list them. Files that contain information about the failure will be marked in red.

BlueScreenView program window

How to fix the error

Broken equipment

If the equipment is broken, it is unlikely that it will be possible to fix it at home. But sometimes it is enough to turn it off and on again. Suppose, according to the error codes, it became clear that there is no access to RAM. Here's what to do:

  • Power off your computer. Do not just press the "Off" button, but remove the plug from the socket;
  • Open the cover of the system unit;
  • Find RAM boards there;

  • Carefully pull them out of the nest. It is necessary to pull the latch that holds them;
  • Insert them back;
  • Turn on your computer and check if everything works.

The same can be done with hard drive, and with a video adapter, and with sound card. But if you are unfamiliar with internal device computer, it is better to entrust it to professionals. It is not necessary to pull out all the parts from the system unit one by one.

If it does not help, then the equipment has become unusable. It needs to be changed.

Disabling external devices

Very often BSoD appears when hard drives or other hard drives are connected to the computer. external devices. How to fix the "Blue Screen of Death" in this case? Turn off equipment. Try plugging it into a different port. See how it appears in Device Manager. Check if there is next to the model name exclamation point. Update drivers.

Perhaps the problem is not with the computer, but with the port controller. If it is faulty, it must be disabled.

Problems with the file system or hard drive

Run scan and repair system disk. For this:

Go to "Properties"

  • Tab "Service";
  • Button "Check";

Click on "Perform verification"

  • Check all boxes. In particular, the option "Repair bad sectors" is needed;

Check the box next to "Repair bad sectors"

  • Start button;
  • The service will warn that it will start checking at the next system startup;
  • Restart your computer;
  • It will start repairing the disk. This may take a long time. Don't interrupt the process.

Software failure

Here's how to remove the "Blue Screen of Death" if the problem is in the system itself or the programs installed on it:

  • Uninstall everything you installed just before the crash;
  • If it doesn't help, make a backup;
  • Go to Start - Programs - Accessories - System Tools;
  • Press " ";

  • In the window that opens, check the box "Select a restore point";
  • If necessary, check the box "Show all restore points";
  • They show the time it was made. backup copy, and what happened (installation, removal, update);

Recovery points

  • Select a suitable point and confirm;
  • Do not turn off your computer until the recovery is complete.

The system will rollback. It will return to the state it was in before the errors occurred.

Other options

  • Scan the system with a good antivirus;
  • Clean the hard drive from debris. Delete junk files. But don't touch system data. You can use the built-in Windows Services(Start - Programs - Accessories - System Tools - Disk Cleanup) or install programs for this: for example, CCleaner;

CCleaner

  • It makes sense to fix registry errors. But don't do it manually. Use the programs Registry Fix, Registry Boot and the like;
  • If you have an installation disk with the system, try reinstalling it or repairing damaged files;
  • Update all drivers. Download the latest updates.

If a blue screen appears when you turn on

If the Blue Screen of Death appears immediately after turning on the computer, you will not be logged into the system. And it will be difficult to fix something. Therefore, you need to start the PC from a boot disk or drive. If you don't have one, use the Windows installation CD. Also suitable free program from DrWeb - "Live Disk". It can be downloaded from the freedrweb.com website:

  1. When starting the PC (on the very first "frame"), the key will be indicated, which must be pressed to open the settings ("PRESS TO ENTER SETUP"). Usually it is F1, F2, F5 or Del;
  2. Click on it. The BIOS settings will open. In them, all control is tied to the keyboard;
  3. Go to the "Boot" tab;
  4. Paragraph " boot device priority";

This will work if the problem is due to a software glitch. But it won't help if the equipment breaks down.

It is necessary to take care of the system and computer, even if there are no problems. Regularly check the disk for errors, delete from it unnecessary garbage, clean the registry. Don't try to improve PC performance if you don't know how. If you take precautions and monitor the status of the system, the Blue Screen of Death is unlikely to bother you.

You can deal with some failures yourself. But if the BSoD appeared due to a hardware failure, it will have to be changed.
