The most common blue screen of death error codes. Blue screen of death (BSoD) - dealing with errors Deciphering bsod windows 7

Blue Screen of Death (BSoD) users modern computers encounter quite often. The resulting error code 0x00000124 indicates that this is a critical system failure detected by hardware using Windows(WHEA). This means that the problem is caused by one of the computer devices.

Why does error code 0x00000124 occur in different versions of Windows?

Error code 0x00000124 indicates system problems with the computer hardware and can occur in any version of Windows.

Possible reasons

• Software or physical damage RAM.
• The RAM timings set in the BIOS (basic input/output system) have failed.
• Problems with drivers or programs.
• Incorrect settings when overclocking equipment - video card, processor, RAM.
• Violation of the established temperature conditions of the equipment. This could be overheating of the power supply, video card or motherboard, or other components and parts of the computer.
• The BIOS version does not meet the requirements of the newly installed hardware and software.
• Malfunction of the motherboard due to malfunctions.
• Failure when connecting new equipment due to insufficient power from the power supply.
• Irregularities at work hard drive associated with software failures or physical damage to the internal surface of the hard drive.

When error 0x00000124 occurs, the computer immediately shuts down. emergency mode. A blue screen appears, the appearance of which depends on the device you are using. Windows systems, with a message about the problem.

What does the screen look like?

In Windows 2000, the error message and its code are displayed at the top of the screen.

In Windows 8 and Windows 10, the screens are the same. Detailed technical information the error is not displayed, it only says that a failure has occurred and you need to restart the computer.

Blue screen Deaths in Windows 8 and Windows 10

Error 0x00000124 is a kind of fuse against further computer breakdowns. The user must, willy-nilly, solve the problem that has arisen, until which is resolved the system will not be able to operate stably.

It should be noted that the blue screen of death may not be seen at all if automatic system reboot is enabled when a failure occurs. To disable this option, uncheck the “Perform automatic restart” checkbox on the “Options” tab in the “Startup and Recovery” section of the “Advanced” menu of the system properties window. To open it in the main computer “Start” menu, right-click on the “My Computer” tab and select “Properties” from the drop-down list, located at the very bottom. Now you can find out about errors in your computer in a timely manner.

What to do: can I fix everything myself?

If an error occurs with code 0x00000124, you can try to fix it yourself, which is successful in some cases, or contact a service organization for help.

If you have never previously troubleshooted problems associated with various computer malfunctions, then do not do anything yourself without first consulting a professional.

From the description we can conclude that the appearance of error code 0x00000124 indicates serious problems in the computer’s operation that should not be ignored. If you do not take timely measures to troubleshoot the blue screen of death, the system may stop booting altogether.

Blue Screen of Death (BSoD) is a critical system error in operating systems Microsoft Windows. When this fault occurs, the system freezes and data that was changed during operation is not saved. It is one of the most common in the Windows 7 operating system. To fix this problem, you first need to understand the reasons for its occurrence.

The reasons why the BSoD error appears can be divided into 2 general groups: hardware and software. Hardware problems are problems with the hardware in the system unit and various components. Most often, malfunctions occur with RAM and hard drive. But still, malfunctions in the operation of other devices are possible. BSoD can occur due to the following hardware problems:

• Incompatibility of installed equipment (for example, installation additional strip"RAM");
• Failure of components (most often they fail hard drive or RAM);
• Incorrect overclocking of the processor or video card.

The software reasons for the problem are much more extensive. The failure may occur in system services, incorrectly installed drivers or due to malware.

• Inappropriate drivers or conflict of some drivers (incompatibility with the operating system);
• Activity of virus software;
• Application malfunctions (most often, such failures are caused by viruses or software solutions that emulate the application).

Reason 1: Installing a new program or hardware

If you have installed a new software solution, this may result in a blue screen of death. The error could also occur due to software update. Provided that you have carried out such actions, you need to return everything to its previous state. To do this, you need to roll back the system to the moment when no errors were noticed.

The Windows 7 recovery process will start, after which your PC will reboot and the problem should disappear.

Reason 2: Lack of free space

You need to make sure that on the disk where the Windows files, there is necessary free space. Blue Screen of Death and various major problems occur when disk space is full. Clean the disk with system files.

Microsoft advises leaving at least 100 MB free, but as practice shows, it is better to leave 15% of the volume of the system partition.

Reason 3: System update

Try updating Windows 7 to latest version Service Pak. Microsoft consistently releases new patches and update packages for its product. Often, they contain fixes that help fix the BSoD problem.

Reason 4: Drivers

Perform the procedure for updating your system drivers. The vast majority of BSoD errors are related to incorrectly installed drivers that cause this type of problem.

Reason 5: System errors

Check the event log for warnings and errors that may be associated with the blue screen.

Reason 6: BIOS

Incorrect BIOS settings may lead to the appearance BSoD errors. By resetting these settings, you can resolve the BSoD problem. How to do this is described in a separate material.

Reason 7: Hardware component

It is necessary to check that all internal cables, cards and other components of your PC are connected correctly. Elements that are poorly connected can cause a blue screen.

Error codes

Let's look at the most common error codes and their interpretation. This may help troubleshoot the problem.

• INACCESSIBLE BOOT DEVICE– this code means that there is no access to the download section. The boot disk has a defect, the controller is faulty, also incompatible system components may cause a problem;
• KMODE EXCEPTION NOT HANDLED– the problem most likely arose due to problems with the hardware components of the PC. Incorrectly installed drivers or physical hardware failure. It is necessary to check all components one by one;
• NTFS FILE SYSTEM– the problem is caused by system failures Windows files 7. This situation arises due to mechanical damage in the hard drive. Viruses that have written to the boot area of ​​the hard drive cause this malfunction. Damaged logical structures of system files can also lead to malfunction;
• IRQL NOT LESS OR EQUAL- this code means that the BSoD malfunction appeared due to errors in service data or Windows drivers 7;
• PAGE FAULT IN NONPAGED AREA– the parameters that are requested cannot be found in the memory cells. Most often, the reason lies in defects in RAM or incorrect operation antivirus software;
• KERNEL DATA INPAGE ERROR– the system was unable to read the data that was requested from the memory section. The reasons here are: failures in hard drive sectors, problematic issues in the HDD controller, faults in the RAM;
• KERNEL STACK INPAGE ERROR– The OS is not able to read data from the swap file to the hard drive. The reasons for this situation are damage to the HDD device or RAM memory;
• UNEXPECTED KERNEL MODE TRAP– the problem is related to the system kernel, it can be both software and hardware;
• STATUS SYSTEM PROCESS TERMINATED– a logical malfunction that is directly related to drivers or malfunctioning applications.

So, in order to restore the correct operation of Windows 7 and get rid of the BSoD error, first of all, you need to roll back the system to the point of stable operation. If this is not possible, then you should install the latest available updates for your system, check the installed drivers, and test the performance of the PC hardware. Help to resolve the error is also included in the fault code. Using the methods given above, you can get rid of the blue screen of death.

The seventh version of the Windows operating system from Microsoft, although considered one of the most stable, is nevertheless not immune to critical failures. One of the most unpleasant phenomena is the “blue screen of death” in Windows 7. Not every user knows what to do when it appears. Some people believe that the problem will disappear on its own after a reboot (and for good reason). Others believe it will be necessary complete reinstallation Windows 7. But before you decide to fix the problem, you need to know its essence.

BSoD Death Screen: What is it?

So, let's assume that the user experiences a Blue Screen of Death. What to do? Windows 7, as well as any other system in this family, can offer several options for solving the problem, depending on what was the root cause.

But in some cases, in order to get rid of this scourge in the future, you cannot do without special utilities. We’ll dwell on them a little later, but for now let’s see what it is from the point of view of the system itself.

Roughly speaking, BSoD is a kind of protective reaction of Windows to a critical failure in the system when a memory dump occurs. In other words, the system cannot neutralize an error in operation using its own means and because of this it reports that such and such has happened. In each specific case, deciphering the Windows 7 “blue screens of death” can tell a lot. Typically, the message on the monitor begins with the word “STOP” followed by an error code. What does this mean? Yes, only that at the moment some important process was stopped, vital for the functioning of the system as a whole. We’ll look at how to remove the “blue screen of death” in Windows 7 a little later, but for now let’s look at the reasons for its appearance.

Reasons for failures

When examining possible problems, you need to clearly divide them into two large categories: software failures (including the system itself) and physical problems with the equipment (for example, when replacing a hard drive, video card, RAM, etc.).

In addition, in Windows 7, solving problems with such problems may also involve the fact that there is simply not enough space on the hard drive, which is especially noticeable when automatic system updates are turned on.

Classification of groups

Today, there are two main groups of failures. Group “A” includes problems with updating or replacing hardware, updating drivers or the system itself, and damage to system components. Incompatible versions are included in group “B” primary system BIOS I/O, driver mismatch specific device, driver conflicts, lack of space on the hard drive, failure of hardware components computer system, overheating of the processor or power supply, power outages, malfunctions of RAM sticks, problems with video cards, results of overlocking (overclocking), etc.

Windows 7 Blue Screen of Death Codes

As you can see, there can be many reasons for errors and failures. In any case, when such a screen appears, you should first pay attention to the description that is present at the bottom of the message. Separately, we can highlight the most common codes that occur most often:

• 0x0000006B;
• 0x00000000 (0022);
• 0x0000007E;
• 0xC0000005;
• 0x80000003;
• 0x80000002;
• 0x804E518E;
• 0xFC938104;
• 0xFC937E04 and others.

Of course, the list is not limited to just these codes (you never know what situation may arise). However, the most common one that appears is the Blue Screen of Death (0x0000007E), in which case Windows 7 displays a description indicating that some exception was not handled.

But that's just brief information. To view full description error or crash, it is better to use a small utility called Blue Screen View. It is this program that can give the key to understanding how to treat the “blue screen of death” of Windows 7. This can be done using the system’s own tools, which will be discussed further.

Blue Screen of Death: what to do (Windows 7)? The first and simplest solution

In the case where the failure is short-term, for example, due to a sudden power outage and a transfer to the unit uninterruptible power supply, you can use a regular reboot with a forced shutdown by long pressing the power button.

But if the “blue screen of death” occurs when booting Windows 7 will appear again, this will already indicate serious damage. To begin with, you can try to simply disable the recording of dumps and mini-dumps. This is done through the properties section, called up from the right-click menu on the computer icon, where you need to through the tab additional settings go to the download and recovery point. In the settings window, you need to disable automatic reboot and recording of small dumps, and then perform a complete restart of the system.

If even after this the problem is not resolved, it is very likely that it is no longer software glitch, but physical damage to the hardware (most often the problem is the hard drive and RAM).

Viruses

One of the reasons for failures may be viruses and malicious codes that deliberately affect the system. They cause a lot of trouble by overwriting system components and replacing them with their own files, and can also cause a “blue screen of death.” What to do? Windows 7 has no tools in this case, apart from its own primitive tools in the form of a defender and a firewall.

In the simplest case, you should check the system with a standard anti-virus scanner, but most likely you will have to use more powerful programs. The best option There will be a free disk utility, Kaspersky Rescue Disk, which can perform its own loading even before the system starts and detect viruses that have embedded themselves deep in the RAM.

System component failures

If it is the system that is damaged, recovery may not work. In this case, it is best to boot into Safe mode Made using the F8 key at startup, and then, if you have constant access to the Internet, perform an online recovery using command line, run as administrator, the command that is shown in the image below.

The process will take 5-10 minutes, after which you should enter the sfc /scannow command and wait for the scan verdict. If the integrity of Windows 7 is compromised, system files will be restored automatically.

Lack of space on the hard drive

Lack of space in the system partition can also lead to the “blue screen of death” in Windows 7. How to fix the situation? To do this, the system has its own disk cleaning tool. It is advisable to use it, and not modules of optimization programs, since the latter do not interfere with the system part.

In Explorer, right-clicking on the disk or partition being checked brings up the properties menu, in which, on the tab general settings you can see the clear button. After clicking it, in the window you should select all components to be deleted and confirm your actions.

Incorrect installation of updates

Quite often, the cause of BSoD is incorrectly installed or underloaded updates. It makes no difference whether it's on automatic update, or the search for updates was carried out manually.

How to remove the Windows 7 Blue Screen of Death in this case? You need to go to the appropriate section of the “Control Panel” and view the latest installed updates. They will have to be removed one by one, rebooting the system each time after uninstallation. Perhaps they are the reason. IN as a last resort, if you don’t want to do such things manually, you can try to roll back the system to its previous state. But it is worth considering that when enabled automatic installation updates will be integrated into the system again.

But in the first case, having found out which update failed, it can be excluded from the list when searching again manually.

Hard drive errors and damage

The most problematic situation is when the cause of the failure is the hard drive. In the simplest case, you will have to check it for errors.

To do this, use the checker from the properties menu, but in the settings the lines for automatic error correction and correction of failed clusters are activated. The same procedure can be performed from the command console, where you need to enter the line chkdsk /x /f /r.

If the damage to the hard drive is physical, nothing can be done, although some experts recommend using special program hard drive magnetization reversal called HDD Regenerator. True, there are legitimate doubts about the fact that it is possible to restore a disk this way (in the sense of using software). Nevertheless…

BIOS incompatibility

Another problem - outdated or incompatible with the system BIOS firmware. The screen will appear directly at startup. In this situation, there is nothing left but to contact the manufacturer’s resource on the Internet. As is already clear, you need to download the firmware and install it.

Information about the BIOS version can be obtained in the system information section, which is called by the msinfo32 command from the Run console (Win + R).

Incorrectly installed drivers

But most often, the appearance of the deadly screen is influenced by drivers or conflicts between them (the most common problems arise with video cards). At the same time, if you access the “Device Manager” (command devmgmt.msc in the “Run” console or the section of the same name in the “Control Panel”), it is not recommended to update drivers.

It is best to remove the problematic driver and then install it from scratch. In some cases, this may not give a positive result. Therefore, you will have to completely remove the device. When restarting the system, it is advisable not to use the installation of the most suitable driver from its own database, but to install it, for example, from the Driver Pack Solution catalog or pre-load required driver from the equipment manufacturer's website.

But to search for the driver itself, first in the same “Device Manager” for the problematic component you need to find the VEN and DEV identifiers in the properties and go to the details tab, where you select the hardware ID display from the drop-down list. To be safe, it is best to use the longest line in the description.

Damaged RAM

But let's assume that the Blue Screen of Death appears again. What to do? Windows 7 seems to have exhausted its capabilities. Apparently the problem is in the RAM.

The cause of the failure can be determined by using the appropriate testing program. The most powerful utility- Memtest86+. But there is also the other side of the coin. On desktop PCs, you can simply remove memory sticks from the slots on each motherboard, overload the system and look at its behavior. You can’t do this with laptops, so you’ll have to contact service center.

Problems with the remote control program

Finally, although infrequently, there is a problem with remote access programs. Specifically, this is an error in the Win32k.sys file. A way out of this situation may be to simply remove the faulty application. Only it is better to uninstall not using system tools, but use programs like iObit Uninstaller for this, which can not only delete the main program files, but also completely clean the system of residual files, folders and even system registry entries.

Instead of an afterword

As can be seen from all of the above, there can be quite a lot of reasons for failures in the form of BSoD. And it won’t always be appropriate reinstalling Windows 7. Finally, it remains to give advice to the majority of users who believe that such a screen means that the system has crashed. There is nothing too critical about this. In most cases, a simple reboot or reinstallation of drivers helps, of course, provided that there is no physical damage to the hardware.

All Windows 7 OS users have encountered the Blue Screen Of Death at least once in their lives.

For ordinary users, this problem causes serious fear because of its name. Seeing a blue background and white letters on the monitor, they rush to take their computer to a service center, where they are even more frightened.

As a result, the user pays a lot of money to fix this problem.

We will tell you what the Blue Screen of Death is and what you need to do when it appears in Windows 7.

Blue screen of death (BSOD)

Blue screen of death is a system notification about a threatening error in the OS.

There are different errors, so there are also several BSODs. Malfunctions that cause Blue screen of death to appear on the monitor, are divided into two types:

• overheating of the computer hardware (“hardware”);
• system problems in software.

If the cause is overheating of the hardware, then, first of all, you need to make sure that all the fans are working, clean system unit from dust, you may even have to replace the capacitors on the power supply.

Overheating may be caused by problems with the motherboard or other computer components.

If you are not a computer engineer and do not understand hardware, then it is better to seek help from specialists.

For a more accurate diagnosis, take your PC to a service center for repair of office equipment.

If there is no overheating, then the problem is in the software. Often the screen of death appears due to driver incompatibility, but there may be other reasons.

Let's look at them in more detail in the section "Causes of BSOD and ways to solve the problem." Now let's talk about pre-configuring Windows 7 OS.

Setting up the operating system

To determine the cause of the Blue Screen of Death, first of all, you need to disable automatic rebooting of your PC, since the BSOD quickly disappears.

To do this, you need to follow the steps indicated in the video instructions below:

What is a kernel memory dump

Computer information is recorded on a hard drive.

But first, the files go into random access memory (RAM), which is automatically cleared every time the computer is rebooted.

If critical errors occur, using the “kernel memory dump” option, the system will create a so-called DMP file before rebooting.

It will store information about the BSOD.

To open an encrypted DMP file, you need to download a special utility “BlueScreenView” from the official website of the developer of this program.

Now that the computer is prepared, you can begin to fix the error.

Causes of BSOD and ways to solve the problem

Let's look at several examples of solving the problem.

Example No. 1

Let's analyze one of the BSODs.

The first sentence states that a critical error has occurred. The second one displays the reason why the error occurred (DRIVER_IRQL_NOT_LESS_OR_EQUAL).

In this example, it is driver incompatibility. Next comes a standard message from the system with advice on how to solve the problem. We go down to the STOP section.

The error code is indicated here (STOP: 0x000000D1), you need to remember this code.

It is necessary in order to use it to find a solution to any problem that has arisen on your PC on the Internet.

Under the STOP key is the registry file where the error occurred (gv3.sys).

Let's restart the computer, launch the BlueScreenView program and in the window that appears on the screen, we will find a message highlighted in red.

There will be indicated the device whose faulty driver caused the screen of death.

Please update the driver for this device to the latest version.

There are cases when BSOD began to occur after updating the driver. Then, on the contrary, it is necessary to restore old version this driver.

Example No. 2

Consider the following Blue screen of death.

This error can be caused by a number of problems, usually hardware. These problems cannot always be solved at home. NO_PAGES_AVAILABLE means that the system does not find some important files.

Therefore, it is worth checking the condition of the hard drive and RAM.

Try taking out one of the RAM sticks and starting the computer without it. If it starts normally, then clean the RAM slots in the system unit from dust.

This may not help, then you need to replace the RAM.

If the problem is not in the RAM, defragment the hard drive using a special utility such as CCleaner.

This will organize the files and reduce the load on the hard drive.

Example No. 3

This blue screen indicates that the error was caused manually by pressing some key combination. But such an error can also be caused by a virus.

To get rid of it, you need to clean your computer's registry. You can, of course, use special utilities, such as CCleaner, but then the dump files will be deleted, which is undesirable.

Therefore, we will clean the registry manually.

Below the STOP line we see that the error was caused by reproducing the kbdhid.sys file. Let's find it in the registry.

To do this you need:

• Open the “Start” menu and enter the “regedit” command in the “search” and press the “Enter” key.
• In the registry editor that opens, select “Edit”, then “Find” or press the key combination “Ctrl” + “F”.
• Enter the folder name with the extension (kbdhid.sys).

After that, in the found kbdhid.sys folder, open the files double click left mouse button. In the file type REG_SZ you need to set the value “Default”.

In a file of type REG_DWORD, set the value as brackets.

It must be remembered that if there are numbers in brackets of two digits or more, then in the “value” field we enter signs (numbers or Latin letters) after x without leading zeros.

After these steps, restart your computer. The blue screen will no longer appear.

Example No. 4

This BSOD was caused by an outdated driver.

To fix this error, let's go below the STOP section. Under the second sign “***” we will find the name of the outdated driver. We need to update it.

Example No. 5

The first time you connect any USB device, for example, a Flash drive, the system automatically installs its driver.

Therefore, the OS recognizes this device. But there are situations when the system cannot find the driver, then the OS becomes incompatible with the USB device, and the Windows 7 blue screen of death appears. What to do in this case?

To fix this error, you need to remove the flash drive from USB connector, restart the computer, find the driver yourself and install it manually on the system drive C:\Program Files.

After this, you can safely use this “flash drive”.

Conclusion

Now you know that if a blue screen of death appears, there is no need to panic. We looked at the most common types of BSOD.

We hope that this information will help you cope with this little trouble on your own.

Today we will tell you what the Windows 7 blue screen of death is and what to do when it appears. We often encounter this phenomenon when the computer suddenly decides to randomly reboot. The Windows 7 Blue Screen of Death displays error codes along with many obscure messages. Knowing the meaning of the main codes will help eliminate the problem as efficiently as possible. If we see a blue screen, this means that the operating system cannot correct the situation on its own. The screen ends with a reboot, and all unsaved data is often lost. The main reasons for this phenomenon are: software errors, problems with PC hardware elements.

Reasons for the appearance of BSOD - screen of death

The Windows 7 Blue Screen of Death occurs due to problems in individual devices of the computer system or errors in the drivers responsible for supporting these devices. BSOD in some cases occurs due to a failure in the operating system kernel; it is commonly called low-level software.

Using the operating system to determine the causes of a failure is not easy, but it will help us BlueScreenView program. This application independently scans error data files and shows more detailed information about failures.

The classic Event Viewer tool theoretically allows you to get similar information, but in this case it will be displayed along with information from the system log and messages about application crashes. BlueScreenView receives information about all screens of death that have occurred in the system.

Here you can see a lot of useful information about the failure, among other things:

• The driver that caused the error.
• Description of the error.
• Error code.
• Time and date the error occurred.

Let's name the main reasons for the occurrence of a “blue screen”:

• Most often, the problem lies in a driver failure of one of the computer system devices.
• Failure of a PC component, such as, for example, a video card or RAM.
• Incorrect overclocking of RAM or processor.
• configured with errors.
• Incompatible hardware, conflict of individual PC components.
• The computer is overheating.
• Viruses have appeared in the system.

Advanced users and developers can use a more sophisticated tool from Microsoft called WinDbg.

Error codes

0x00000001

This code may appear if there are difficulties with the Compositebus.sys driver. When a portable or multimedia device is first connected to a PC, it installs the driver and resets the USB. The error is caused by simultaneous access to Compositebus.sys. If you try to install a third-party driver, a similar failure may occur.

0x00000002

The device queue was not busy. The problem lies in the drivers or hardware. To correct the situation, you need to update the drivers. The computer also needs to be scanned for viruses. The registry needs to be cleaned. It will also be useful to check your hard drive for errors. If this does not help, update your operating system to the latest version.

0x00000003

The error is also caused by hardware environments. The fix algorithm is already familiar to us: we check the hard drive for failures, clean the registry, look for viruses, eliminate them, update drivers. If all this turns out to be useless, download it to your computer current version Windows operating system.

0x00000004

This code indicates an exceptional data access condition. The cause of the failure may be PC hardware or device drivers. We are already familiar with the recipe: remove everything unnecessary, eliminate viruses, update driver versions. If this does not help, you will have to switch to a more modern operating system.

0x00000005

This failure is due to a coding error in the Http.sys element. Operating system will have to update so that the situation does not repeat itself. This error occurs when the driver calls the KeAttachProcess function and a problem occurs if the thread is occupied by another process. Using the KeStackAttachProcess function may become more efficient in this situation.

0x00000006

This error is also related to KeAttachProcess. Going to the KeStackAttachProcess function will also help here. Among others possible reasons this failure: a breakdown in the power supply, memory failure, overheating. It is necessary to check the health of the power supply, test the hard drive and make sure that there are no viruses in the system. If this does not help, update the operating system.
