What to do if the blue screen on the computer. A blue screen appears

20.10.2019

Blue screen death (BSOD) - a message about a critical system error, placed on a blue background of the computer screen. BSOD (Blue Screen of Death) displays information about a serious Windows crash that has occurred, shows the name and stop codes of the error.

The "Blue Screen of Death" appears due to computer hardware problems or malfunctions software. The causes of BSoD can be very different: driver conflicts, device conflicts, application conflicts, virus exposure, etc.

Starting with the version of Windows 8, the design of the "blue screen of death" has somewhat changed. Now the error message does not look as ominous as before, when the blue screen scared many users. In Windows 10, the blue screen displays minimal information.

To identify the causes of critical system errors, you can use the software, in particular, the free program, about which there is an article on my website.

There are situations when, on the contrary, it is required to artificially cause a blue screen for research purposes. For example, you need to run diagnostics, get screenshots during a BSoD, check the operation of programs, etc. I needed this opportunity to demonstrate the operation of the BlueScreenView program when I wrote an article about this application.

How to cause a blue screen? Exists different ways artificial start BSOD on the computer. In this article, we will look at 2 ways that cause a BSOD on a computer: using keyboard keys, after editing the registry, and using the Not My Fault program.

Before experimenting with an artificial blue screen call, take care of the safety of data on the computer: create, or create. Research with the launch of a BSOD is best done on to protect the physical computer from possible appearance problems.

Disable Windows automatic restart on system failure

In Windows 10, Windows 8.1, Windows 8 operating systems, it is necessary to disable automatic restart in case of system failure, because the user may not understand the reason for restarting the computer.

To change the settings, we need to enter the advanced system settings. This can be done in several ways.

Open your computer's Control Panel, and then click the System icon (in the Small Icons view).
In the "View basic information about your computer" window, click the "Advanced system settings" link.
In the "System Properties" window, in the "Advanced" tab, in the "Startup and Recovery" section, click on the "Settings ..." button.
In the "Startup and Recovery" window, in the "System failure" section, uncheck the box next to the "Perform automatic restart" item.
Click on the "OK" button.

Press "Win" + "R" on your keyboard.
In the Run window: "systempropertiesadvanced" (without quotes).
Next, from the "System Properties" window, from the "Advanced" tab, in the "Startup and Recovery" section, click on "Settings ...".
In the "Startup and Recovery" window, disable the automatic system reboot that occurs in the event of a system failure.
Apply this setting.

How to cause blue screen of death in Windows

This method works on Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows XP operating systems. The Scroll Lock key is used to change the behavior or position of the mouse cursor. Among other things, the key has a function with which developers can get a memory dump, artificially causing a "blue screen of death" to debug the system.

The default BSOD call feature is disabled in Windows settings. The user can independently enable this functionality for use for their own purposes.

To do this, you need to make changes to the Windows registry. Open the Registry Editor in one of the ways.

Follow the path if you are using a keyboard connected via a PS/2 port:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters

If the keyboard is connected via USB, go to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdhid\Parameters

Enter the "Parameters" section, right-click on an empty space.

From the context menu, select "New" and then "DWORD (32-bit) Value".

Name the setting "CrashOnCtrlScroll" (without quotes).

Right-click on the parameter and select "Edit..." from the context menu.

In the "Edit DWORD (32-bit) Value" window, in the "Value" field, insert the parameter "1" (without quotes), and then click on the "OK" button.

Restart your computer to apply the settings.

Now, if necessary, we call the Windows blue screen of death by pressing the right “Ctrl” key and double-clicking the “Scroll Lock” (“ScrLk”) key on the keyboard.

If there is no need for such a BSOD start on the computer, delete the previously created settings from the system registry.

How to Blue Screen Windows in Not My Fault

Free program Not My Fault created by Mark Russinovich to cause an artificial failure operating system due to various reasons. Going forward, Windows will behave the way the system behaves after a real problem occurs, so it's best to test this application in a virtual machine.

Download the Not My Fault utility from here. Unzip the archive with the program, and then run the application file from the program folder, in accordance with the bitness of your system. The Not My Fault program does not require installation on your computer.

In the Not My Fault program window, in the "Crash" tab, take the appropriate cause of a critical system failure:

High IRQL fault (kernel-mode).
buffer overflow.
code overflow.
Stack trash.
High IRQL fault (User-mode).
stack overflow.
hardcoded breakpoint.
double free.

Click on the "Crash" button.

A BSoD will open on the computer with an error that caused the system to crash.

Article Conclusions

If necessary, the user can artificially cause a “blue screen of death” on the computer to perform the necessary work: performing diagnostics, creating snapshots, etc. The Not My Fault utility has a choice of BSOD occurrence parameters for conducting the necessary research.

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.

As a rule, system default settings are set in such a way that in the event 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 "Advanced system settings". 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 automatic restart" checkbox. Save the changes you have made.

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, to fix it, it will be enough to restore the system, or even better, reinstall it, and this error will no longer appear.

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.

Good day to all. Have you ever had this - here you are working, you are working for yourself, you are sitting on the Internet, and then bang a blue screen with white letters on English language, all sorts of numbers, and you can return to work again only after pressing the reset () button on the case system block? This phenomenon is called - Blue Screen of Death BSOD. The most annoying thing. Today I will tell you about this muck, what it is and how to deal with it.

General information

I'll try to briefly describe what it is. Blue screen of death BSOD. This screen appears when a fatal error occurs in the Windows operating system due to which the OS cannot continue further work. All the system can do is write the cause of this error to a special dump file. Next, a message is displayed on the screen about the cause of the error and what caused it, then reboot or not, depending on the settings. Everything else that you did not have time to save will be irretrievably lost. In general, the blue screen of death is not so bad on the one hand, because it signals to the user that there is a serious problem in his computer that needs to be urgently resolved. If the screen appeared once or twice, then in principle you can forget about it. but if it pops up regularly, then this is a cause for concern.

Blue screen what it looks like

When I first heard about this phenomenon, I thought: maybe I already had a similar case, because I saw a couple of such screens? Let's figure out which is which.

bios setup. Screen with BIOS settings. This program contains the hardware settings for your computer. You can get into the BIOS only at the very beginning of the PC boot by pressing the Del key. If you accidentally pressed this key and saw this window, then do not be alarmed, this is not a blue screen of death. Press Esc to exit.

Check disk error screen, operation of the Chkdsk program. This program is started most often as a result of improper termination Windows systems. For example, you have turned off the light, but there is no uninterruptible power supply. Or too lazy to wait for the system to complete, you just pull the plug out of the socket. After such a case, this screen may pop up. OS will start as soon as the program Chkdsk will finish his work.

But this is already Blue Screen of Death BSOD

A red screen of death has been encountered in Win Vista. If you have met this, then know that these are all the berries of one field.

Causes of the blue screen of death

Driver failures. This is the most common reason.
Incorrect, "Left drivers".
Application conflict. This may include a failure in the operation of antiviruses ( if they were installed not one, but two), firewalls .
Hardware failures. Overheating of the processor, defective RAM chips, or simply badly inserted RAM chips into the slots, errors on the hard drive. Failures in the operation of the video card, the motherboard with the devices that are placed on it.
Viruses, but this is rare.

Decryption

Now consider those hieroglyphs that appear on the screen.
The text we see before technical information, describes the error and what needs to be done to fix it.

Technical Information contains the following:

error code
the name of the driver in which the error occurred
error location address

Enabling recording of debug information (dumps)

So we are gradually moving to practical action. As mentioned above, when a critical error occurs, the system can store information about this error in a special file. By default, this feature is disabled on the system. You need to turn it on. And usually the computer restarts immediately after an error, this also needs to be fixed.

For users Windows XP:

Start— Control Panel – System— – Parameters— System failure.

Uncheck the box, in the box Writing debug information, put Small memory dump after click OK. The small dump folder is also indicated just below. Typically, dump files are stored in C:WindowsMinidump.

For users Windows Vista/7:
Start - Control Panel - System - Advanced - Download and Recovery - Settings. Uncheck Perform automatic reboot press OK.

The blue screen can also be forced. For what? And to find out the current problems of the operating system. This is done by double pressing the key. SCROLL LOCK while holding down a key CTRL. But for this to work, this feature must be enabled. It is done like this:

Launching the Registry Editor Start — Run — regedit
Let's move on to HKEY_LOCAL_MACHINE-System-CurrentControlSet-Services-i8042prt-Parameters.
Create a new parameter DWORD With name CrashOnCtrlScroll and assign it a value 1 .
We restart the PC. Well, then, as written above, we clamp CTRL and twice for SCROLL LOCK.

Analyzing BSOD Dumps

In this section, I will tell you about how you can identify the cause of the blue screen of death practically ( although it may not be possible for a novice user). Most often, problems with a blue screen arise precisely because of the drivers, then dump analysis will help identify this driver and eliminate the cause of the error and further failures.

Program blue screen view designed for dump analysis. Free and easy to use. Download and install. After starting, point to the folder with dumps.

Eliminate the causes of the blue screen of death

Eliminating the causes can be a very difficult task. But still in some cases this problem is completely solvable. The following describes how to solve the most common cases.

By now you should already have the name of the file that is causing the error. The name of the file and the program or driver to which it refers:

afw.sys, afwcore.sys and filtnt.sys — Agnitum Outpost.
spider.sys, dwprot.sys — Dr. Web.
rt*** and alc***- device driver Realtek. Usually this is a sound or network card.
cnx***- device driver Conexant.
nv***- device driver nVidia. Usually it's the video card.
ati***- device driver ATI. Usually it's the video card.
ig***- device driver Intel. Usually this is an integrated video core from Intel.

When a problematic driver or program is found, they should be updated or replaced with other versions. Check the RAM for errors with the program memtest86 because Often blue screen of death BSOD pops up as a result of memory problems.

Well, that seems to be all for now.

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 disk, RAM, network card, video adapter may be damaged;

The cause of the problem may be a defective hard drive.

An incompatible device or equipment is connected. 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 a huge number of errors. Even licensed programs are not immune from them. 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") is a number 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 software bugs for the Sound Blaster Live sound card;
"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 system installation or incorrect configuration;
"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". The Windows system kernel does not have 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 a hard drive, and with a video adapter, and with a sound card. But if you are unfamiliar with the internal structure of a 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 external devices are connected to the computer. 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 mark. 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 System Disk Check and Repair. For this:

Right click on it;
Item "Properties";

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 unnecessary 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:

When you start 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;
Click on it. The BIOS settings will open. In them, all control is tied to the keyboard;
Go to the "Boot" tab;
Item "Boot Device Priority";
There will be a load order. Put in the first place the device from which you plan to load data (disk or drive);
Open the "Save" section, select the "Save and reset" option;
Now the computer will start from external media (do not forget to insert it);
If it's a boot disk or CD with Win distributions, try reinstalling them;
Live Disk also has tools for resuscitation of the system;
After recovery, change the boot order again to start from the hard disk.

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, remove unnecessary garbage from it, 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.
