What Blue Screen Means On Computer

Blue screen appears

No matter how the computer owner is an inexperienced user, sooner or later he may encounter a symptom such as a blue screen. This usually means that the computer is in serious trouble, and it’s time to invite the wizard.

What is a blue screen?

The concept of “blue screen of death” has been known since the advent of the first versions of Windows. Outwardly, it appears as English-language inscriptions in white letters on a blue background. At the same time, it is often possible to get rid of it by rebooting the computer with or without the RESET button, or by turning off the power and turning it on again.

The appearance of a blue screen signals a problem in the system, so it is not recommended to ignore such symptoms. It is urgent to carry out computer diagnostics, as when a blue screen appears, after a while you can get a completely inoperative computer, lose important data, etc.

History

What Blue Screen Means On Computer

The term “blue screen” appeared thanks to Eric Noes, who introduced it in 1991, working for one of the California companies. During the development of the first versions of Windows (then designated as 1.0 and 2.0), error messages were displayed on black screens, but they changed it to blue, which is better perceived by the eyes and not so annoying.

Since then, including the latest common modifications of Windows 8, the screen continues to turn blue when critical errors occur. If we look at the origins of the transition to it, then we can note that the original name of this type of error sounds in English as Blue Screen of Death, abbreviated BSoD.

Stop code

This is also the name of the blue screen that appears due to a critical error that does not allow the operating system to fully function. For this reason, a decision is made to stop its work with the conclusion of a message about it. Not just symbols appear on the monitor, but a description in English of the reason and the most optimal ways to eliminate them.

There is a whole list of different codes that have, in addition to text, a digital designation starting with 0x (then comes the digital combination in the 16th calculus system). The information is intended for a technical specialist, a simple user is usually powerless to understand something. Although you can try to find a description of the error on the Internet by entering the phrase “bsod codes” as a search query.

Why does a blue screen appear?

The list of crashes and problems that cause the blue screen is quite large. And not always a textual description accurately indicates the true cause. By studying the description of the main STOP errors, you can find out the most likely node where the malfunction occurs, but only the master can reliably verify it.

Replacement Parts

What Blue Screen Means On Computer

It’s easier to find out the reason why this blue screen appears when some actions were performed with the computer: upgrade, updating drivers or the operating system. So, the replacement of individual components, for example, memory modules, a video card, a hard disk, can lead to a chance to see a STOP error.

The reason may be the malfunction of the devices themselves and their incompatibility with new models. After upgrading the hardware, it is recommended to do this with the driver of the replaced device. Otherwise, the problem may occur from the periodic display of a system shutdown message on the monitor screen, to a closed cycle without a chance of starting Windows to correct the situation (reinstalling the driver, removing it, etc.).

In the simplest case, it is enough to restart the computer, in more complex situations, at least for a while, you will have to return the old hardware. It is worth noting. with this error, all unsaved data that the user was working with at the time the blue screen was issued is lost.

Keyboard misuse

There are cases when the blue screen is called up by pressing certain buttons on the keyboard, or rather their combination. This can happen by chance, for example, a child has sat down at a PC or intentionally, they do this when they want to show their knowledge of the "subtleties" of Windows.

In this case, the appearance of a blue screen is not a manifestation of problems, but an artificial call to the function of displaying an error message. It does not have any danger, but it can lead to loss of unsaved data or system malfunctions, because for it it is still a “problem”, the recovery function may be activated, as a result of which time will be lost.

What to do when BSoD appears?

The first thing that is required from the user is to restart the computer using the RESET button or by turning off the power and turning it on again. If the error message reappears, then it is necessary to diagnose the hardware.

Often the cause of BSoD messages is this equipment:

    What Blue Screen Means On Computer
  • HDD. To fix the alleged crashes, you need to use a utility such as CHKDSK, it is included with Windows. Use it to search for bad sectors, followed by automatic recovery. If it does not help, you should resort to specialized programs from a developer such as Acronis.
  • RAM modules. There may be several reasons: failure due to a power surge or overheating, incompatibility of the new module with the old or with the motherboard. Sometimes it helps to simply rearrange the modules or clean the contacts with an eraser. There are special utilities for diagnosing memory, but you can also use a regular tool called WMD (to start the program, you must enter the mdsched command in the Run line). This method works in Windows 7 and above, you need to press a key combination to bring up a command prompt window.
  • BIOS settings failed. The reason most often lies in the discharged battery that is located on the motherboard. It must be replaced. Either the user himself has entered the wrong parameters, sometimes problems appear after installing new motherboards on the motherboard that do not support previously performance characteristics. The easiest way is to reset the settings using the jumper or the corresponding menu item in the BIOS settings.
  • Computer viruses. They can cause both damage to hard disk sectors and software errors that can be fixed after they are removed. They do this with the help of anti-virus programs and other specialized utilities.

All these procedures are for the most part accessible to all users in complexity, but if in doubt, it is worth contacting an experienced master.

Can a blue screen be avoided?

A number of preventative procedures can help prevent problems that cause a blue screen to appear. They should be carried out systematically.

  • It is necessary to use anti-virus programs, regularly update them.
  • It is worth refusing to install a large number of unverified programs.
  • Use drivers downloaded only from official sites.
  • Using special programs, it is necessary to clean the system of debris (temporary files that interfere with the normal operation of the computer).

It is important to monitor the relevance of the drivers and programs used. Gradually, developers cease to support obsolete equipment, and it may not work correctly with new versions of programs. And, most importantly. if there are doubts about the correctness of the actions, it is better to contact a qualified master.

So what is it and how to deal with the “blue face”, which does not please PC users at all? Let’s start from afar. As you may know, computer operation is an extremely complex interaction between tens and hundreds of devices that are “forced” to share system resources. From time to time, errors may occur, which, among other things, lead to a computer freeze. If the blue screen of Windows 7 suddenly appeared in front of you, then a very serious kernel-level error occurred in the system.

Unfortunately, when buying a computer in any large network of household appliances, you are not immune from such unpleasant consequences. As a rule, they don’t bother to check the components for compatibility with each other, as a result of which you may have a lot of problems. It is advisable to select such equipment only at specialized retail outlets.

However, the blue screen in Windows 7 can be caused by ineptly written programs. Although most often this happens when a user tries to install outdated versions of software that are incompatible with his operating system. Of course, this practically does not happen when installing trivial small utilities, but in the case of antiviruses, firewalls and hard drive emulators, such problems are not excluded. A classic case is when the blue screen of Windows 7 arose in the first months of its release after installing the Alcohol 120% program due to all the same problems with the drivers.

If, however, it is not possible to establish the reason for certain, you probably can not do without going to the service center, where they can more accurately determine the cause of the ailment of your iron friend. In any case, it does not hurt to talk with an experienced specialist.

The appearance of a blue screen is a sign that the operating system cannot work further. Its occurrence is accompanied by a high-priority interruption of Windows and a forced reboot of the system without saving the results of its functioning.

Windows operates in two modes: user mode and kernel mode. In the first, the operating system launches all user applications, system processes and services, and in the second, the components of the operating system interact with the equipment through special programs. drivers. It is when a serious malfunction occurs at the level of functioning of the kernel of the operating system that the “blue screen of death” arises, which is accompanied by the appearance on the display of a message with information about the error on a characteristic blue background.

Causes of Critical System Failures

There are many prerequisites for interrupting the operation of the operating system with the subsequent display of BSoD, and the main drivers of the interruption of Windows with the appearance of the blue screen of death are device drivers. According to statistics from Microsoft, they account for more than 70% of BSoD cases. The reason for the order of 15-20% of the occurrence of such errors is failures in the drivers of various emulators, antivirus programs, virtualization tools, firewalls and system libraries (DirectX, C, Framework).
