Blue window of death. Blue screen of death what to do

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 that a complete reinstallation of Windows 7 will be required. But before you decide to fix the problem, you need to know what it is.

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 will 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. Group “B” includes incompatible versions of the primary BIOS input/output system, driver mismatch for a specific device, driver conflicts, lack of space on the hard drive, breakdowns of hardware components of the computer system, overheating of the processor or power supply, power outages, malfunctions of the boards RAM, problems with video cards, overlocking (overclocking) results, 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 this is just a brief information. To view a full description of the error or failure, 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 switch to an 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” appears again when loading Windows 7, 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 go through the additional settings tab to the boot and recovery item. 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 this is not a software failure, 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 would be the free disk utility Kaspersky Rescue Disk, which can boot itself before the system starts and detect viruses that have embedded themselves deep into 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 Made mode using the F8 key at startup, and then, if you have constant access to the Internet, perform an online recovery using the command shown in the image below in the command line running as administrator.

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, where you can see a cleanup button on the general settings tab. 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 automatic updating is enabled or whether the search for updates was done 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. 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’s worth considering that if automatic installation is enabled, the 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.

Errors and damage to the hard drive

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 a special hard drive magnetization reversal program 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 is outdated or incompatible 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-download the 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 is Memtest86+. But there is also the other side of the coin. On desktop PCs, you can simply remove the memory sticks from the slots on the motherboard one by one, reboot the system and look at its behavior. You can’t do this with laptops, so you’ll have to contact a service center.

Problems with the remote control program

Finally, although not often, there is a problem with remote access programs. Specifically, this is an error in the Win32k.sys file. The 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 is not always appropriate to reinstall Windows 7. Finally, it remains to give advice to the majority of users who believe that such a screen means 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.

What is BSoD

BSoD - Blue Sceen of Death, blue screen of death. Appears in the most critical situations, when closing a faulty program is impossible.

The Windows operating system has several layers of running programs. We see only the top one - open program windows and running services. These are what the Task Manager shows. When one of the programs makes an error that it is not able to process and work around, it, as many users say, “crashes.” You can start it again and continue working.

Software modules running at a lower level (drivers) will not be able to restart in the event of an error. The Windows operating system tries to protect the user from many errors, but this does not always work and it capitulates, showing a sad face or a set of characters on the computer screen.

You need to understand that drivers are an intermediary between the software and hardware of a computer. Both drivers can fail (programmers are people too, they may not take something into account or make a mistake), as well as the hardware part of the computer.

Symptoms of BSoD

1. The appearance of a blue screen with strange symbols or a sad emoticon.

In 99% of cases, the computer reboots on its own due to a critical error (BSoD), but there can be a worse situation: problems with the power supply or motherboard. If you have a desktop PC, check to see if there are any bulges anywhere.

Reasons for a blue screen

1. Overheating. Overheating of the video card or processor leads to the blue screen of death.

By the way, in Windows XP, when the video card overheated, a BSoD always occurred; in Vista and newer, the video driver simply rebooted. If you see the message “The video driver has stopped responding and has been restored,” then this is an overheating of the video card:

The newer Windows, the better the protection against failures. Let's hope that in some Windows XV, instead of a blue screen, we will see an error notification that does not interfere with work.

2. RAM failure. It’s possible, but in order not to hit the mark, read on first - perhaps the cause of your blue screen of death is something else.

If you installed new RAM in your computer and get frequent BSoDs, replace it at the store with a working one. There are no other ways to overcome blue screens of death when replacing RAM.

3. Failure of other hardware. Maybe the voltage in the power supply “sags”. Maybe there is a loss of contact somewhere. Maybe your computer doesn't like the full moon. There are many reasons, one can guess endlessly.

If, after you have analyzed the minidump (more on this below) and eliminated errors, the blue screen does not go away, you should replace all components one by one. You can’t just go ahead and determine the cause of BSoD if the error codes are different every time.

4. Overclocking. If you are an advanced overclocker, then you know what overclocking a computer has to do with BSoD. If not, don't overclock your computer.

5. Driver(s) failure. The cause of BSoD is not necessarily a hardware problem. Unstable drivers are a frequent guest on user computers. How to identify a faulty driver will be discussed next.

6. Viruses. Be sure to check your computer with some or .

I never tire of being amazed at the self-confidence of users who say “ I have no viruses and no antivirus either! I have a straight hand/I only use trusted sites/sometimes I check with a one-time antivirus and that’s why everything is fine!". Leaving aside the debate about how you can live without an antivirus, think about it: if a person sees BSoD, he has This is no longer a normal situation. How can you say that there are no viruses and this is not the cause of the blue screen?

Also, do not think that if you have an antivirus installed with the latest databases, there cannot be viruses. Check with others to completely rule out the possibility.

7. Antiviruses. It's funny (and sad) that antiviruses can cause crashes. Remove your antivirus temporarily. Have blue screens of death stopped appearing? Install a new one so that blue screens do not appear due to reason No. 6.

8. Windows updates. Developers at Microsoft sometimes test updates poorly. Because of this, some people completely disable Windows Update and sit without updates, although this is not an option. Control Panel - Programs and Features - View installed updates- right click - Delete according to the updates installed recently, then check the operation of Windows. Has everything returned to normal? Just don't install updates for a couple of weeks - usually during this time some kind of corrective update for the update comes out and everything becomes fine.

9. Programs crash. This happens, but rarely. If you see BSoD during a game or when running a specific program, I advise you to check your computer for overheating, because most programs are not capable of causing a blue screen, with the exception of those installing drivers into the system (antiviruses, virtual disk emulators, game protection systems like PunkBuster, accounting programs that work with digital keys).

10. Hard disk file system errors. It won't be amiss

Let's find out the cause of BSoD

As you can see, there are quite a lot of reasons and there is no point in guessing. Fortunately, the Blue Screen of Death contains clues as to why Windows suddenly started to crash. Among the incomprehensible text there will be error codes containing a direct indication of what caused the failure.

Most often you are BSoD you won't see, since Windows settings by default enable restarting the computer in case of critical errors.

You can disable automatic restart of Windows like this: Control Panel - System - Advanced System Settings - Options- check/uncheck the boxes as in the screenshot below:

Pay attention to the “Small memory dump” item - check it too.

Google the error code from the Windows Log

The “Write event to system log” checkbox is checked by default, which means error codes will be in the Windows Log.

Go to Control Panel - Administration - Event Viewer - System- and look for a line in the list that coincides in time with the appearance of a blue screen or restarting the computer:

Look for the error code (in the screenshot above it is 0x0000009f) in Google and read the first few sites in the results, follow the recommendations that have helped others. If a driver is specified (a word ending .sys, then it’s generally great - the likely culprit was found immediately, you need to install a driver for this device of an older/newer version. If there is no clear and clear indication on the Internet of the cause of BSoD for the specified error code, read my instructions further.

If there is nothing in the Windows Log, wait for the blue screen to appear and look for the error there:

Just search Google for information on the error code and follow the recommendations.

Analyze the minidump

Unfortunately, if the problem is a faulty driver, this is not always shown on the blue screen. The error code is also not always informative. You need to analyze the minidump file that is created when a BSoD occurs and contains information about the failure, in particular which drivers reported the error. There are two programs for minidump analysis: Windows Debugging Tools and BlueScreenView. Unfortunately, the first one is too complicated for novice users, although it gives a more informative result. In 99% of cases, the second, simple and free BlueScreenView is enough.

The BlueScreenView installer is available at this link.

After starting the program, you will see a window in which at the top there will be minidumps created by the system and information about them, at the bottom - a list of drivers. Failed drivers will be indicated in yellow.

Example No. 1 - the video card is to blame

A blue screen appears with the text ATTEMPTED_WRITE_TO_READONLY_MEMORY. Let's look at the minidump:

The ATTEMPTED_WRITE_TO_READONLY_MEMORY error, judging by googling, is caused by some driver. The likely culprit in this case is nv4_disp.sys. There are others, but they are part of the system and are statistically unlikely to be the cause. A Google search showed that nv4_disp.sys is a video card driver from nVidia. Three steps:

1. Check the video card for overheating.

2. Installing an older video card driver (new if the old one is installed). This is done with any drivers, not just video cards.

3. Installing the video card in another computer.

4. If a blue screen appears on another computer, take the video card to a service center. If the warranty is still valid, you can replace it with a working one free of charge.

5. Doesn't the blue screen appear on another computer? Try installing a different power supply on yours - this may be the reason.

6. Doesn't help? Reinstall Windows completely.

7. If this does not help, take it to the service center for diagnostics.

Example No. 2 - the culprit is not at all what was expected

A blue screen with the message PAGE_FAULT_IN_NONPAGED_AREA is associated with many problems:

If the likely faulty driver was ntfs.sys, then I would recommend checking the hard drive for errors, and also replacing the cable that goes from the hard drive to the motherboard. In this case, BlueScreenView points to the USB port driver and this could be true, but where I took the dump from as an example, the person’s motherboard is at fault - the capacitors on it are swollen. The solution is to pick up the system unit and head to the service center.

Example No. 3 - the antivirus is to blame

I found this minidump on the Internet:

The culprit was SRTSP.SYS, an antivirus component from Norton. Solved by removing it.

Example No. 4 - “broken” RAM

A blue screen with MEMORY_MANAGEMENT is a sign that the RAM is unusable:

BlueScreenView points to the likely culprit - ntoskrnl.exe. This is the Windows kernel and cannot be the cause of the BSOD. In 99% of cases, the cause of a blue screen with the MEMORY_MANAGEMENT error is “broken” RAM. We'll have to change it.

Results of the analysis of examples

1. BlueScreenView indicates a failure in the driver, and the hardware with which the driver interacts may be to blame.

2. You can determine whether the failure is in the driver or the hardware by searching through both the drivers and the hardware. Install old drivers (for example, those included on the disk), download new ones.

In case of critical errors in the operation of the operating system, as a result of which the PC is rebooted without saving data, and further work with information becomes impossible, a blue background with white letters is displayed on the screen, which is called. The name is a literal translation of the English term Blue Screen of Death (abbreviation BSoD).

Causes and consequences of BSoD

You should not be afraid of a blue screen, since any mechanism can fail sooner or later, but determining its cause can be quite difficult. BSoD is a kind of protective reaction of the operating system and appears when code is detected that does not work correctly.

Operation on PC is not possible because the system is shutting down. The user remains to carefully study the information received and then reboot the system.

Thus, the blue screen provides information about the type of error by encrypting it using hexadecimal code. Identification of the cause of the failure (deciphering the code) can be found in a search engine.

Some breakdowns in the system are very frequent, others are quite rare. For example, 0x00000001 corresponds to the APC_INDEX_MISMATCH error. When entering the code, we learn that the problem occurs as a result of the first installation or reinstallation of a third-party application for MTP and WPD devices. This error can be fixed by downloading and reinstalling the latest update to the OS.

Delaying the error on the screen

If the user, having seen what is happening on the screen, does not take any action, Windows will automatically begin to reboot. In this mode, in the absence of technical knowledge and experience, it is difficult to understand the source of the failure. As a result, there is a need to delay the error on the PC screen.

To make it possible to decipher the sources of failures that have occurred, you can go in several ways:

  • photograph the indicators;
  • view memory dump entries;
  • use the diagnostic utility.

Recording the contents of working memory is enabled after rebooting is disabled in automatic mode. To do this, activate the “Properties” tab in the “Computer” menu (using the mouse button on the right or using the quick combination “Win+Pause”). In the “Advanced system settings” position, located on the left side of the screen, open the “Advanced” window.

In the selected tab we find the “Download and Recovery” item with a number of checkboxes. Next, you need to remove the parameter that performs auto-reboot and check the box that is responsible for recording the event in the system log (“Record event in system log”). Now, when a blue screen appears, the OS will not automatically reboot, and the necessary information about the dysfunction of the working system will be stored in memory.

Using a special application is relevant for high-speed diagnosing blue screen of death. For example, the Blue Screen View utility examines individual dumps, organizing them into a list.

The program carefully analyzes and collects information about the details of critical failures that occur and displays products in decrypted form, indicating the version and bit depth. Events are viewed in separate windows of the resulting report, which can be saved in text format or a .html file.

How to Analyze BSoD Information

On the blue screen of death, information in English is located in a certain sequence, specifying the failure and how to resolve it. In particular, we are talking about displaying:

  • fault names;
  • recommendations for its elimination;
  • hexadecimal error code;
  • failure parameters;
  • driver name;
  • fault addresses.

Failures that occur due to a breakdown of a PC hardware element (hard drive, RAM, video card or power supply) are common. It is not uncommon for conflicts to arise between devices on a computer or due to incompatibility of connected equipment with.

Inappropriate or incompatible drivers, lack of free working space on the disk, poor functioning of coolers leading to overheating, the action of malware are no less common circumstances that lead to the appearance of the screen of death.

The main reasons that cause OS failures

The appearance of a Windows 7 blue screen of death when loading is a fairly serious reason to analyze the operation of the PC as a whole.

First, you can check how much disk space is left for system data. If there is no space, you should delete unnecessary information in the usual way or using cleaning utilities.

Periodically, it is necessary to scan the OS with antiviruses in order to destroy viruses, Trojans and other software that disrupt the operation of the PC.

If the activation of the blue screen is caused by errors in Windows 7 codes, you can install the update package in the latest version and periodically update the system in the future. For this purpose, in the “System Properties” menu, select the “Automatic update” item, in which the corresponding “Automatic (recommended)” button is activated.

If the failure occurs when downloading a program or driver again, the error can be resolved by rolling back the driver to a previous version or uninstalling the program. You can use "Run Last Known Good Configuration".

The activation of a blue screen is sometimes associated with connecting a new incompatible device to the PC. Then one of the components is replaced - either the device (with a compatible one) or the operating system that supports it.

If the device is initially compatible, but the OS still gives an error, new versions of drivers obtained from the manufacturer’s website are installed.

If you have the appropriate knowledge, you can set the settings in the BIOS. It is better for a non-professional not to use this technique, since the result can be an even bigger problem than a blue screen.

The screen of death may be a consequence of problems with RAM. A broken ruler is detected using one of the testing programs. Thus, the MemTest86 utility allows you to test memory without an OS or connecting other drivers. To connect it, a bootable flash drive (disk) is created. The program writes the entire memory in blocks of data, and then reads and checks what was written.

BSoD can be caused by bad sectors or errors on the hard drive. The problem is solved through standard operations: the volume is checked in the “Service” menu.

It would be a good idea to keep your PC clean, which will eliminate the problem of overheating, which causes the blue screen of death to appear. It is necessary to lubricate the cooling components of the processor, chipset, and power supply with a special product. If necessary, additional coolers are installed to ensure normalization of air flow.

To resolve BSoD, you can reinstall the operating system using its licensed version.

General algorithm of actions for solving the BSoD problem without decryption

If there is a problem in the form of a blue screen, you can do without deciphering the error code. First, let’s analyze our recent actions with the computer. If their list includes updating a driver, installing a program, changing the registry, replacing equipment, or visiting a site with a dubious reputation, you can do things differently.

First, the OS boots when using the “Last Known Good Configuration” mode. To do this, all disks are removed and the computer is restarted. While rebooting, holding down the F8 key causes the Windows symbol to appear. Then the PC should be restarted again and, having received the message “Additional boot options” on the screen, select the “Last Known Good Configuration” item.

If this attempt was unsuccessful and did not lead to the elimination of errors, the computer is booted in “Safe Mode” (alternatively, “...with loading network drivers”).

After this, you can check the disk, the integrity of its system components and the presence of viruses.

So, the blue screen helps to identify failures that occur during code execution in the kernel operating mode. To do this, it is enough to keep your PC clean, use drivers and proven programs downloaded from the official resources of reliable manufacturers. By following simple rules, you can reduce the possibility of system interruption by several times.

If BSoD begins to periodically disrupt the usual rhythm of PC operation, you can easily decipher the error code and then eliminate its cause.

Windows 7, if there are errors in the system or incorrectly functioning computer components, stops working and displays the “Blue Screen of Death”, also called “BSoD”. Then the system points out possible problems that caused the failure and provides recommendations for solving them. The Blue Screen of Death displays the hexadecimal error code and its parameters. After the code comes the name of the driver and the address of the error.

Thus, the blue screen of death upon boot carries a significant amount of important information for the user and helps to fix Windows 7 to remove BSoD.

You just need to carefully read (it’s better to even take a photo of it) with the data provided and analyze at what address and what error occurred.

Analysis of the causes of BSoD

To establish the reasons why such a failure occurs with the appearance of a blue screen of death, you need to familiarize yourself with its main list:

  1. Increase in temperature of PC equipment exceeding operating values;
  2. Drivers. Failures and incompatibility of this software installed on the computer;
  3. Incompatibility of applications installed on the computer, for example, between antivirus utilities;
  4. Conflict of computer components;
  5. It is rare, but it happens that the Blue Screen of Death causes the PC to become infected with malware;
  6. Failure of devices included with the computer, for example, hard drive, RAM, etc.;

There are many reasons for the appearance of the blue screen of death, and they need to be identified as soon as possible, otherwise any of the PC equipment may break down and cannot be restored.

What actions need to be taken?

If the Blue Screen of Death appears on your computer display, you must take the following steps:


Analysis of the source of problems to determine specific causes:

  1. Often, “BSoD” is a consequence of the inexperience of the computer owner, for example, it happens that the user deletes a system file or utility. In this case, you will need to return Windows 7 to the state before it was affected by an inexperienced user and perform the following steps:
  2. Through the Start menu in search "System Restore" and click on the displayed file;
  3. determine the restore point; it must be earlier in date than the time when the user made incorrect changes to the system;
  4. Ready. These steps will remove BSoD. Windows 7 should now boot without problems.
  5. In the case where the user did not delete the necessary data or utilities from the system, then it will be necessary to identify the reason for its appearance from the records on “BSoD”, i.e. identify the file or program (driver) that caused the system error and the appearance of the blue screen of death. Next, type the name of the utility or file in the search and remove - uninstall them. From the official resources of the equipment manufacturers, proceed to download and install them on your PC.
  6. Perform an analysis to determine the reasons for the increase in temperature of PC equipment exceeding operating values. To do this, you should resort to downloading and installing special applications, for example Aida or Spessy (they work great in Windows 7). After installation, they will show the operating temperature of the PC equipment and identify bottlenecks in specific parts of the computer hardware. If temperatures exceeding critical values ​​are detected in any equipment, these components will need to be repaired or new ones purchased.

Memory dump

This is the contents of memory at a specific period of time. After canceling the automatic actions of Windows 7 that lead to booting the system, it is recommended to enable memory dump recording. To do this, you need to follow a simple algorithm of actions:

Examining a Memory Dump

This can be done using the BlueScreenView program, which allows you to extract the necessary data from the dump.

Blue Screen of Death (BSoD) is a critical system error in Microsoft Windows operating systems. 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, failures in the operation of other devices are possible. BSoD can occur due to the following hardware problems:

  • Incompatibility of installed equipment (for example, installing an additional RAM strip);
  • Failure of components (most often the hard drive or RAM fails);
  • 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 a 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 the disk where the Windows files are located has the required 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 the latest version of the Service Pack. 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

Reason 6: BIOS

Incorrect BIOS settings can result in a BSoD error. 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 is defective, the controller is faulty, or incompatible system components may cause the 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 failures of Windows 7 system files. This situation occurs 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 7 drivers;
  • 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 of anti-virus 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 unable 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.
