“In a nutshell,” a blue screen appears when a stop error occurs (operating system kernel error) during which the system can no longer continue to operate. The problem is typical for any failure - from software incompatibility to excessive processor temperature. In order to more or less accurately determine the cause of the failure, an analysis is necessary based on the text and code of the error itself. Desktop or laptop – it doesn’t matter, the approach to solving problems is the same.
Disabling automatic reboot
Analysis of the problem by code
Once we receive the code, we will be able to find information describing the cause of the problem and how to solve it.
Getting the code on Windows 8 and later
More modern codes have less description and technical information, and the code itself is represented by a sad smiley face and a text description, for example, CLOCK_WATCHDOG_TIMEOUT:
also, in addition to the error (sometimes without inscriptions or text), a QR code may be present:
Codes in Windows 7 and older
When a blue screen appears, you need to find the error code. It looks like 0x0000..., for example, 0x0000008D:
* codes in brackets are additional parameters and are used to clarify the location of the error. They can be individual and, as a rule, are not taken into account in further analysis.
Online analysis
Now we open sites with error codes, for example:
You can also enter the error code directly into the Google or Yandex search bar. And if there is a QR code, you can consider it a reader and proceed to the description of the problem.
When solving the problem, you must carefully read about the causes of the failure and follow the recommendations.
Analysis by dumps
In the case when automatic reboot is enabled or we are analyzing the problem later, we can use a dump - a special file that contains information about the last state of the system before the error with all the necessary descriptions and codes.
By default, this file is located at %SystemRoot%\MEMORY.DMP (usually C:\Windows\MEMORY.DMP). You can view or change the path in the same place where automatic restart is disabled - right-click on This computer - Properties - Advanced System Settings -
You can read the dump using a special utility, for example, BlueScreenView. You can download it on the official website.
After launching the utility, we should see (if there were problems) a list of stop errors with codes, reports and additional information:
Having received the error code, we carry out an analysis using search engines or specialized sites using the method.
TOP error codes
- 0x00000109. A general error caused by incorrect operation of RAM or disk media. Sometimes because of a virus.
- 0x00000050. There is a problem with the device driver or incorrect hardware operation.
- 0x0000007B. It is necessary to check the media and the system boot order in the BIOS.
- 0x0000007e. Common code that covers a large number of different problems. Read the article below about common problems and methods for solving them.
- 0x00000012. The system was unable to understand the cause of the failure. For a solution, also use the text below.
Typical causes that lead to errors and methods for eliminating them
Let's look at the TOP problems that cause operating system kernel errors, as well as methods for solving them:
- There is a problem with the device driver. If the error appears after installing a new driver or updating it, you must roll back the driver to the previous version.
- Windows update failed. It usually happens when installing a large number of updates or installing a low-quality patch. Solved by rolling back installed packages.
- Incorrect operation of the equipment. To find out, you need to conduct a stress test with AIDA64 or analogues. It is also necessary to test the RAM and disk drive operation.
- Reset BIOS settings. When changing the drive operating mode (AHCI, IDE, RAID), the system will stop booting and display a stop error. The parameter may be lost due to a dead BIOS battery or a manual reset.
- Viruses. Many problems can be attributed to them. But it’s worth checking your computer, for example, with the CureIt program.
- Incompatible software. If installing or updating any programs resulted in a problem, reinstall the software product or install a previous version.
- Violation of the license agreement. In some cases, a blue screen may appear every hour or two. As a rule, this is due to the fact that Windows is not activated.
- There is a problem with the video card or it is overheating. As a rule, it is observed in games or when watching videos. To diagnose, you need to update the driver and conduct a stress test. It is also worth paying attention to the temperature of the video card.
If the system does not boot
In some cases, BSOD appears when Windows boots. This makes diagnosis much more difficult. In the case when the system cannot be booted, and the blue screen appears for a moment, or does not appear at all, you need to disable automatic reboot when turned on.
Another option is to use a bootable Windows LiveCD, which contains a large number of utilities to help diagnose the problem.
The Windows 7 blue screen of death, also known as BSOD (blue screen of dearh), appears when a critical error occurs in the operating system, due to which it is impossible to continue using the computer. Typically, this error occurs due to the fault of system drivers, but this does not always happen. It is worth noting that despite its menacing appearance, the error is often solved quite simply, which many users do not know about. Sometimes it even goes away on its own after rebooting the system. Therefore, in this article, I will tell you what this “Blue Screen of Death” error is, when it occurs and how it can be overcome.
It is noteworthy that every operating system has this kind of error, for example, in Linux this is akin to the “Kernel Panic” error.
The Windows 7 operating system provides many different tools to solve error problems. For example, if you have noticed, when an error appears in individual programs, the system itself continues to execute, showing you only a small window with text.
However, Windows 7 is essentially the same set of programs. Internal mechanisms allow you to cope with a number of your own errors, but there are also those after which the system simply cannot continue its execution. These errors are insoluble and the only thing the system can do in this case is to warn the user about them, and then perform an emergency reboot of the computer.
Since errors can be related to the video card, they are displayed in the simplest form, namely in the form of white or yellow text on a blue background, which fully describes the situation in which a critical system failure occurred. Actually, because of the background and fatality of the error, it received the name “Blue Screen of Death”, which became the basis of many existing jokes about Windows 7.
For most users, only two fragments of the entire typing are important; they are shown in the figure below:
As you can see, the first fragment is an inscription with uppercase letters and an underscore separator, and the second fragment is a description of files and codes. These are the ones that need to be written down or remembered, and then look for their decryption on the Internet or on the Microsoft website.
Possible causes of the Windows 7 Blue Screen of Death error
Before you try to solve a problem, you need to understand its source. There can be many of them, but there are the most basic ones:
1. Problems with drivers. Unlike ordinary programs, not everything is simple with drivers. Their errors can be critical for the operating system and therefore cannot simply be taken and restarted. For example, one of the common errors is a problem with network card drivers. In such cases, a simple reinstallation of the drivers is usually sufficient.
2. Lack of free space on the system disk. The operating system, during its execution, like some programs, creates temporary files on the system disk, so if at a critical moment there is no disk space, the system may display the “Windows 7 Blue Screen of Death”. This problem can be solved by simply cleaning the system disk.
3. Another error is damage to important system files. In this case, it is necessary to restore Windows 7.
4. Registry errors. This kind of error occurs very rarely, but it does happen. In this case, you need to search for a solution on the Internet using the text from the blue screen of death.
5. Equipment breakdown. Errors can arise not only from programs and this is also important to take into account. For example, static on the motherboard can cause the screen of death to appear. Or normal computer overheating. At home, it is not always possible to cope with these types of errors. For example, with cooling you can solve the problem yourself, but with statics only if you have the tools and appropriate skills.
In most cases, errors occur due to some changes in the system configuration, for example, reinstalling drivers or installing specific programs, so loading Windows 7 with the last known good configuration can solve the problem (sometimes just a reboot is enough). However, I advise you to look on the Internet for the true cause of the error after loading the system. Returning, here are instructions on how to load the latest configuration:
1. Restart your computer and wait until after the first information screen, the screen turns black.
2. At this point, press the F8 key to display a menu as shown in the figure above.
3. Within 30 seconds, select “Run with last known good configurations” from the items and press the enter button.
If the problem is not solved, then you need to try to start the system in safe mode; to do this, in step 3 you need to select the appropriate item. In other cases, you need to look for an explanation of the error on the Internet and the appropriate way to solve it. However, it is also useful to know something about diagnostics.
The problem with the Windows 7 blue screen of death is not only the error itself, but also the fact that by default, this error is displayed for only a few seconds. This is done so that an abandoned computer due to an accidental failure will reboot without user help and “possibly” continue to function (if the error disappears after a reboot). Be that as it may, this is quite inconvenient when diagnosing, but this feature can be disabled and here’s how it’s done:
One of the biggest annoyances that users have to face is the critical OS error that causes the Windows Blue Screen of Death. Today we will analyze the reasons for its occurrence and consider methods to eliminate it.
The “blue screen of death” got its name from the background color on which error data is displayed. For shortening, the English name was transformed into the abbreviation BSOD. To understand the reasons for this, let's look at the architecture of Windows NT operating systems. In general, thanks to its modular structure, the OS divides all running processes into user processes and those executed in kernel mode. The former have limited access to system resources and peripherals, while the latter have unlimited access. BSOD errors occur at the kernel level when the system detects a critical code error or an inability to perform operations. In this case, the operation of the OS immediately stops, and unsaved data is deleted.
Causes
Since kernel errors are considered critical, Microsoft is forced to respond to them and keeps statistics on their occurrence. The aggregated data looks like this:
- 70% - drivers are not working properly;
- 15% - unknown reasons;
- 10% - hardware configuration failure;
- 5% - errors in Windows executable code.
Unfortunately, there is no detailed information regarding drivers. However, the available information is sufficient to localize the problem with a high degree of probability.
Error data output
For the lucky users who have never encountered a BSOD, we will show you what the Windows 7 blue screen of death looks like.
The following data is displayed on the monitor:
- Text error code.
- Primary recommendations for its elimination.
- Technical information with error codes.
The blue screen in Windows 10 has changed its tone, and the amount of information displayed has been significantly reduced.
Now the user has access to the following data:
- Link to a web page that describes the problem and how to resolve it.
- Text information with an error code for calling technical support.
- QR code. It is assumed that the user reads it using a smartphone and is taken to a page describing the problem.
Usually the computer reboots after a few seconds to prevent damage to the hardware configuration. Let's figure out what to do if you did not have time to read the information necessary for diagnosis.
Disabling automatic reboot
Settings related to how the OS behaves in the event of critical failures can be changed. Launch the control panel and go to the section indicated in the screenshot.
In the window that appears, select the item marked in the quick jump area.
In the “System Failure” block, uncheck the box indicated by the arrow and confirm your decision.
Now, when a Windows 7 blue screen error occurs, you can read the technical information displayed on the monitor.
Additional error information
If the cause of the blue screen of death in Windows 7 has not been established from preliminary information, the user can study additional information. Any event that occurs is recorded in the system log, which can be accessed using the control panel.
Select the section marked in the screenshot.
A list of administration parameters in which we are interested in the event viewer will open.
On the left side, expand the list of Windows logs. A list of system events will appear in the middle area of the window. By checking the error notification you find, you can view details about the culprit.
Full details of the crash can be retrieved from the automatically generated dump file. To do this, you will need to download a special utility. The simplest and does not require installation is BlueScreenView. On the developer’s website you can additionally download a file with a Russian translation of the interface. By using it to open the dump created by the system, you can analyze in detail the Windows 7 blue screen error codes that appear.
Restoring functionality
It is better to leave the study of the reasons that led to a failure in the system kernel to specialists. They will be able to read BSOD codes much better than the average user. Let's look at how, following Microsoft's recommendations, you can remove the blue screen of death yourself.
- If any changes were made to the BIOS before the OS crash, return the settings to their original state and disconnect peripheral devices. If possible, we also try to return the hardware configuration to a state that ensured stable operation. For example, if the error appeared after replacing components, replace the old video card or RAM sticks. Thus, we undo all recent physical actions on the PC that could lead to the system error.
- You can fix a blue screen caused by software errors by installing the latest OS updates or the latest driver versions from the manufacturer’s website. In some cases, on the contrary, you have to roll back the system to a stable state using restore points.
- We test the hardware configuration to identify any errors or conflicts.
Checking HDD and RAM
Open "Explorer". In the quick jump menu, select “Computer”. Having selected the system drive, call up the context menu.
In the HDD properties, go to the “Service” tab and open the item indicated by the arrow.
We check both parameters in order to not only identify, but also, if possible, eliminate existing errors. Let's start the check.
Since the selected disk contains a running OS, we will be prompted to check it upon reboot. We agree to this condition by clicking the marked button.
Go to the control panel and again find the administration section. Open the list of tools it contains and select the marked one.
We use the first point for diagnostics. Now, having rebooted the computer, we will conduct two hardware configuration tests at once.
The RAM check is performed first.
Next, testing of the hard drive starts.
If there are errors, information about them will be displayed on the screen after Windows starts.
Windows 10
All the described steps also apply to Windows 10, since both operating systems are based on the same NT kernel. To avoid switching between the old and new interface, it is better for the user to immediately open the classic control panel. The required sections are marked in the screenshot.
It is worth recognizing that there is no universal way to cure a PC from BSOD errors. Differences in hardware configurations require an individual approach in each case. The most “neglected” options can only be “treated” by completely reinstalling the OS.
Almost every user has, if not encountered, then certainly heard about such a thing as the “Windows blue screen of death.” This topic is extensive, so read carefully! In the article we will discuss what a blue screen of death is, what to do in this situation, and of course, I will try to show everything clearly. The name for this phenomenon was invented just right - frightening and memorable. In today's article I will take a detailed look at the causes of the blue screen of death, as well as possible solutions to this problem.
Blue Screen of Death is a serious problem that baffles PC users. Before you start reading the article, I recommend that you put all your affairs aside and so that no one distracts you. If you understand the essence of the occurrence and solution to this problem, then in practice it will be much easier. I have been approached with this problem more than once, and there have even been situations when in their practice administrators did not know what to do when a blue screen occurred. In return, they told users that they needed to replace the system unit completely. WHAT? If you were told so, then take the noodles off your ears and read the article to the end.
What is this error
As a result of a problem, the operating system (OS), being unable to correct the error on its own, urgently shuts down. Naturally, no user data is saved (open documents, etc.). The only thing Windows manages to do is write information in the log and create a dump file, if the settings indicate the creation of this file when such errors occur.
To avoid unfair accusations against Windows, I’ll immediately make a disclaimer: the blue screen of death does not appear without serious reasons, and shutting down in such a situation is the only way out.
The blue screen of death looks like this:
From the screenshot, I think it’s clear where the word “blue” came from in the title. As for “death,” this means the death of the operating system, that is, its inevitable reboot, and in some cases, reinstallation. In practice, most causes of blue screens of death can be successfully eliminated without reinstalling the OS, provided, of course, that the response is timely and correct. The most important thing is to understand where the legs come from. I mean that if you don’t know why the blue screen of death appears, then it’s difficult to solve the problem.
What does Windows tell us on the terrible blue screen of death?
To make it easier to understand, I will conditionally divide it into several blocks and describe each one separately (for those who know English, independent understanding of most of it will not be difficult).
1. Here Windows reports that a problem has been found, and to prevent damage to the computer, it was necessary to urgently shut down the system.
2. The type of error is indicated here. There are a limited number of them, and for each such error, information can be easily found on the Internet.
3. In this part, the OS reports possible causes of the problem, and also gives some recommendations for troubleshooting.
4. In the section called “Technical information” the error code is indicated, and it is also possible to indicate the name of the problematic driver (more details below).
After viewing the blue screen, you should understand what the error is or find out about the file that may be listed on the screen.
Causes of Blue Screen of Death
The Blue Screen of Death can appear for various reasons.
The most common reason is drivers. This includes drivers that are incompatible with each other or with the operating system, and other failures associated with them.
In this case, I have a short story, this information is not only for you to read and forget!!! With this story, you will learn how to solve the Blue Screen of Death problem.
I once worked as an administrative assistant and maintained a fleet of 80 computers. Almost 20 computers experienced a blue screen of death from time to time. When I asked the administrator about the reasons for this misfortune, he just shrugged his shoulders and said that he didn’t understand what was going on at all (I think he just didn’t want to figure it out). After his answer, I became interested in finding the essence of the problem myself.
First of all, I looked at what error appeared on the screen, then wrote down on a piece of paper the error code and the name of the file that the blue screen of death pointed to. After wandering around the Internet a little, I found out that this file is used for Wi-Fi adapters. After that, I did a short walk around the problem computers and made sure that they were all really working on the network via Wi-Fi adapters.
Next, I decided to find out what drivers the administrator installs when connecting these devices. His answer left me stumped. It turned out that he installed the drivers that came with the equipment. After that, I spent 2 hours, but still found a topic that interested me on the Internet. It turned out that these particular devices are buggy with standard drivers.
It’s strange, because D-link is considered one of the best, but in reality it turns out that it supplies drivers for adapters that do not work with them. At that time, a topic with a similar problem had already been created on the d-link manufacturer’s forum. And for about 2 years now, many users of these adapters have had this problem.
To get out of our situation, it was decided to use other drivers (from other developers). We installed them on the problem computer and asked the user to be sure to notify us if a blue screen of death appears. Of course, I didn’t know which drivers to install instead of the official ones. After reading completely all the topics on the forum, I found a dozen reviews that tried a different driver (I don’t remember which one now) and this problem was solved for them.
A few days later he still didn’t call or visit us, which means that no more problems arose! After making sure that everything was fine with his computer, we installed this driver on all computers and users breathed a sigh of relief.
Problems with computer hardware.
Often problems with hardware are more of a consequence, but the cause may be overheating of components. This also includes self-inflicted problems with hardware, RAM or hard drive.
Problems with programs.
The screen of death can be caused by antivirus applications and various emulators. Also, sometimes the blue screen of death is caused by viruses; this doesn’t happen often, but it also happens.
What do we have to do
First, you need to prepare in advance for potential problems. Windows is configured by default so that the screen of death appears for just a couple of seconds, after which the computer automatically restarts.
However, this does not give us the opportunity to have time to record error data, which does not suit us at all.
Note: If it does not reboot automatically, then use the “Power” button.
It will be enough for us to configure Windows so that it does not automatically reboot. Thus, we can understand why the blue screen of death appears. Since in this error you can read the error code or file that is to blame for the blue screen of death. After this, the Internet will help us. To set this up you need to do the following:
On Windows XP: “Start” - “Settings” - “Control Panel” - “System” - “Advanced” - “Boot and Recovery” - “Settings” - “System Failure”. In the window that appears, you need to uncheck the “Perform automatic reboot” checkbox, and in the “Record debugging information” block, select “Small memory dump”, and click the “OK” button.
In Windows Vista/7: “Start” – “Control Panel” – “System and Security” – “System” – “Advanced system settings”. In the window that appears, select the “Advanced” tab, the “Boot and Recovery” subsection, and click the “Options” button. All that remains is to uncheck “Perform automatic reboot”, enable a small memory dump and click “OK”.
You can also get to this window by right-clicking on “Computer” - select “Properties” - on the left click “Advanced system settings” - go to the “Advanced” tab - for me this method seems easier.
Secondly, when the blue “enemy” first appears, you need to write down the data from the blue screen on paper. This data can help in finding the cause of the problem.
Well, thirdly, let’s show you how to remove the blue screen of death.
You need to understand that the death screen appears much more often after some user action than on its own. Therefore, the first thing to do is to try to return the computer to the state in which it worked stably.
If no special manipulations were carried out with the computer, that is, you were just working, and suddenly “He” appeared, you will have to look for answers on the Internet. Since the most common cause of BSOD is drivers, the first priority is to find the name of the faulty driver.
If the information was indicated on the death screen itself, then in this case we only need to find a description of the error or problem that the driver caused. To do this, simply enter the name of the known faulty file in any search engine. This way we find out what kind of file it is. For example, if this file is needed for the video card to work, then you need to remove the video card drivers and download a new one from the office. manufacturer's website.
Otherwise, the search must begin with the data that you have transcribed manually. Using this information, you can roughly navigate the possible causes. If we couldn’t find out anything useful, we move on to analyzing the memory dump.
Do not install various assemblies that were made by unknown authors. If your neighbor Uncle Vasya even advised you to install his assembly, then my advice to you is - DO NOT DO THAT! It is better to install a full-fledged original Windows distribution and you will be happy.
If problems with drivers have not been identified, you need to check the hardware components of the computer, which may be the cause of the blue screen of death. First of all, this is RAM, hard drive or overheating of any system components (video card or processor). You can use the AIDA program to check the temperature.
If you think that the problem is with the hardware, then borrow this part from your friend from his computer and install it on yours. Once you are sure that this particular part is working unstable on your computer, you can then buy it in the store.
To test RAM, I recommend the MemTest86 program, and to test the hard drive, the Victoria program (I will describe a detailed discussion of the operation of these programs in separate articles). In addition, it would not hurt to conduct a full virus scan by first updating the virus signature database.
Let me remind you that a dump is a file that is created at the moment a problem occurs and contains a detailed description of the state of the system at the time the error occurred, and, therefore, can tell about the reason for the failure.
Let's imagine a situation where your friend has a blue screen of death. He does not understand what it is and why the blue screen of death appeared. Naturally, he turns off the computer and tries to find out from his friends what it was. Of course, he didn’t write anything down on the piece of paper, that is, he doesn’t know what was written, but as you already know, in order to solve this problem you need to know why the error appeared.
There are special programs just for this, with which you can find out what the reason was. Now, even if you are in another city, you know how you can help your friend. You can use Debugging Tools for Windows or BlueScreenView to view the contents of the dump.
Let's use the BlueScreenView program as an example to figure out how to view dumps. Download the Russified program for a 32-bit system.
Now run the file “BlueScreenView.exe”.
If there are no lines at the top, then there were no failures on your computer.
I didn't have the blue screen of death and so I had to borrow it ;). So now we have a dump that will help us understand how this program works.
To indicate the dump that I have, I need to make changes to the program. To do this, click “Settings” - “Advanced options” or “CRTL” + “O”.
Click “Browse” and indicate where our dump is located.
Note: If the program is on the problem computer, then nothing needs to be changed.
Now we see which files caused the error. Right-click on the line and select “Properties”.
Copy the “File Name” and go to any search engine to find out what kind of file it is.
After a couple of minutes we understand that this file is a video card driver. This is how in a few minutes you can understand the cause of the blue screen of death. But sometimes it takes an hour or more to find out the reasons.
I hope that now you will not have any difficulties in solving the blue screen of death problem.
See you soon!
A must-watch video, because there is something here that cannot be described in words:
The screen of death is caused in Windows 7 by system errors classified as critical. The OS freezes and the user's latest changes are not saved.
The situation is not the most pleasant, but it is often found in computers with the “Seventh” modification of the system.
There is no general algorithm of actions to eliminate this problem, since it depends on the causes that caused it. Below are specific recommendations that should be taken to effectively resolve the situation.
Why does the death screen appear?
All the abundance of causes causing BSoD are classified into two large parts:
- Software;
- Hardware.
The first includes failures in system services, incorrectly installed software (including drivers that ensure the normal functioning of the equipment), virus infections of the PC, software conflicts, etc.
The second part of the reasons that cause a blue screen in computers running Windows 7 lies in the hardware. The record holders for popularity are such important PC components as the hard drive and RAM.
Often, after a user installs an additional RAM stick into a PC or due to poor contact in the slot, a blue background with white letters will immediately greet the computer owner. It is also not uncommon for problems with the hard drive to cause critical errors and OS freezes.
The blue screen itself in Windows 7 is of an informational nature. Its text contains recommendations for troubleshooting and notifies the user of the specific error codes that caused it to occur.
That is why you need to carefully study all the inscriptions displayed by the screen of death. By rewriting or remembering the error codes from the bottom of the screen, you can surgically accurately diagnose and quickly get rid of the problem.
Unfortunately, often the user does not have time to familiarize himself with the output report, so this guide begins with a technique for canceling the automatic restart of the PC after an error occurs.
Computer settings
If the user did not have time to capture the necessary information from the screen, then a little PC setup will be required.
After this, once you know the code, you can use it to find an effective “medicine” that can cure your iron friend.
You need to do the following:
It is recommended to study the meaning of the error code on the resource “bsodstop.ru”. For example, “0x0000004e” may appear due to an incorrectly installed driver.
To find out exactly what software caused problems in the system, you should use the BlueScreenView application, which automatically identifies files that cause a critical error. The user only needs to install and open the application.
Based on the detected file, you can find out for which equipment you need to reinstall the drivers. From the above figure we can conclude that there are difficulties with the graphics accelerator, since “ati2dvag.dll” is associated with the video card.
In this case, installing the correct software for the video accelerator will allow you to get rid of the screen of death.
After reinstalling the driver, you need to restart the PC. If the problem could not be corrected, then it means that there are other reasons.
Often the error occurs after updating or installing a new program, and the best way out of the situation is to roll back the OS.
Rollback
A new program or game is also often the culprit of system failures. In order to return the OS to a working state, it is necessary to perform the following sequential steps:
Installing OS updates
Specialists from Microsoft do not stand aside and are making their efforts to troubleshoot problems that cause BSoD.
They continue to support the already outdated “Seven” and release upgrades that include “fixes” that correct system errors that cause blue screens.
To update you will need to do the following:
The next most popular cause of problems is a simple lack of memory in the system partition of the hard drive. Checking this version will not take much time.
Low memory
On the official resource of the Windows 7 developer it is written that for its functioning it requires at least 100 Mb of free space on the system volume, however, practical experience has proven that for the “Seven” to work normally, it is necessary to keep a fifth of the system volume free.
To make sure there is enough space in the partition, you just need to open “Computer” in Explorer.
After making sure that there is enough space for the OS to function, you should proceed to analyzing the presence of system errors through the event log.
Event log analysis
To do this, you need to take the following steps:
Antivirus and viruses
Often, simply disabling the antivirus program will resolve the problem. If, after deactivating the security application, the blue screen no longer appears, then you will need to completely remove the antivirus.
Malicious utilities also cause critical errors, and regular scanning of your PC for their presence is required. Many antivirus software developers have versions of programs that operate from removable media.
For example, "AVZ". By recording the application onto a CD or flash drive, you can treat your PC from malicious utilities.
BIOS
Incorrectly entered parameters in the BIOS also often cause crashes. You can correct the situation by resetting the BIOS settings to the initial state - “default”.
Equipment
A simple inspection of the wear of the cables and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.
If the user has the appropriate experience, it is necessary to open the system unit (SU) and check the connections of all computer components.
For example, when, based on the results of a careful review of the information displayed on the blue screen itself, it is determined that there is no access to RAM, you will need to perform the following actions:
- Turn off PC;
- De-energize the computer by disconnecting it from the power source;
- Remove the SB cover and disconnect the RAM boards;
- Wipe the contacts with a dry cloth and insert the equipment into place;
- Start PC;
- Make sure the problem is resolved.
Similar measures can be taken with other PC components, for example, with a hard drive and sound and video cards. If there is no positive result, then this component may fail and will need to be replaced with a new one.
Equipment diagnostics can be performed using special utilities. For example, “Windows Memory Diagnostic” allows you to identify problems with RAM.
The application writes a boot disk image. This ISO must be cut into a CD and booted from it on the PC. The program will carry out testing in cyclic mode.
To stop the analysis you need to reboot. Windows 7 also has a built-in RAM analysis program. In order to use it, you need to perform the following steps:
To minimize the risk of developing BSOD, the following is recommended:
