Tip 1: Why the computer shuts down

Many users are faced with the problem, when at work a computer he turns himself off. There are several reasons for the unstable operation of PCs, which are the most common.

One possible reason for spontaneous shutdown a computerand may be the presence of viruses in the system. They can appear after visiting unreliable Internet resources; after the installation of software of unknown origin (for example, by reference from an email from an unknown sender or from a message on a social network); after using CDs with unlicensed programs, etc. In any case, if you do not use an antivirus, the risk of infection a computerbut it increases significantly, and the result can be unstable work a computera.To scan the system for infected objects, start the antivirus software you are using. Choose the command "Check now", "Scan now" or similar (depending on the selected program). Wait until the scan is complete. If infected files are detected, disinfect or delete them. Another common cause is processor overheating. In this case, when the temperature reaches a certain mark, a computerbut for security reasons: high temperature can disable both the processor itself and the motherboard. Heating can occur due to a broken or clogged cooler, a high load on the processor, and so on. As a rule, when you turn on again a computerand a warning appears on the screen thatshutdown occurred due to overheating. Often, to eliminate this problem, you need to open the system unit and clean the fan of accumulated dust. Also, the cause may be a weak power supply. When assembling a computerand from individual components is not always truethe required block power is calculated. As a result, this can result in the device being turned off at a high load, for example, during the game process or when working with programs that perform a large number of calculations.

Tip 2: Why the computer shuts down on its own

Most reasons for automatic shutdowncomputer can be divided into two types: software and mechanical. To identify the cause of this behavior, a PC needs to perform a few simple steps.

Instructions

It happens that the computer just turns off orreboots. Check the temperature of the important equipment installed in the personal computer. Most often overheat the following devices: video card, CPU, chipset. Download and install the Everest program or its current version of AIDA. Run the selected software.

Open the "Computer" menu, the iconis located in the left column. Select the "Sensor" item. Wait for the program to scan the hardware. Study the information provided. The temperature of the video card and the processor should not exceed 60 ° C. Run a "heavy" graphics program or game. After 5-10 minutes, fold it and again look at the sensor readings.

Check the operation of the power supply. The simplest option is to replace the device with a similar one for a while. Be sure to remember which equipment was connected to the unit. Pay special attention to the computer's system board. Usually two groups of cables are connected to it.

If you are watching while turning off the computer"Blue screen", check the drivers for installed devices. In order not to reinstall absolutely all the drivers, try to identify equipment that does not work correctly. To do this, enter the error code in the browser's search box. It is usually represented in the form of several combinations of symbols under the Technical information field.

If you could not determine what kind of devicegives an error, reinstall the drivers for the following devices: video card, CPU (chipset). Pay special attention to this item if you work with a laptop. Installation of drivers must be performed in a certain sequence in those cases when there are two video adapters on the computer. First, install the chipset drivers and reboot the mobile PC. Drivers of a video card put last. Use only original programs downloaded from the sites of the manufacturers of a particular device.

Sometimes spontaneous shutdown of the computermay result from the operation of certain programs and services. Open the "Control Panel" and go to the "Power Options" menu. In the field "Put the computer into sleep mode" select the "Never" option. Open additional power options and expand the submenu "Dream". In the "Hibernate after" column, also select the "Never" option.

Check the active programs. The popular utorrent download manager has the function of shutting down the computer after completing uploading files. Disable or remove unused programs.

Tip 3: Why does the computer turn itself off

Sometimes during work at a computer startoccur its sudden shutdown without the knowledge of the user. The reasons for this can be very different, starting with technical problems and ending with the intrigues of virus programs.

Technical reasons

Check how well connected to thethe system unit cables of various devices, especially one that provides power to the computer and is connected to an electrical outlet. Perhaps one of them periodically departs from the socket, which causes a sudden shutdown of the computer. Also, the cables can have various cracks and scrapes, and therefore they must be replaced to resume use of the computer. Make sure that the power supply unit located at the back of the computer has a working cooling system (it does not heat up much and does not make noise during operation) and also has enough power to ensure the computer's performance. If its power is low, tripping may occur to protect the equipment from malfunction or lack of power. Clean the inside of the system unit from dust and dirt. Pay special attention to the fans. The dust deposited on them worsens the cooling of the components, which causes them to overheat, and the computer switches off spontaneously to prevent them from breaking down. With a slightly damp cloth, wipe the chips of various components, and also check the fixing of the internal loops of the system unit.

Software reasons

Think about what programs you installed beforethe way the computer began to shut down spontaneously. Perhaps this or that application or game is too resource intensive, and the capacity of the equipment is not enough for their successful functioning. In this situation, there can be a strong overheating of the processor, video card and other components, which is why the shutdown occurs. Remember, did you change the settings of the operating system or BIOS. Incorrect installation of important parameters can lead to various system errors. Try to restore the system through the appropriate service application by selecting the last date of normal computer operation for the restore point, or to reset the current settings to the ones that were by default. Perform a full scan of the computer for viruses and other malicious programs. It's the viruses that cause such problems as a sudden reboot, a hibernate or shutdown of the computer. In the future, be careful when visiting suspicious websites and downloading unknown programs.

Tip 4: Why the computer turns off for a long time

Often, many users are faced with the fact that their a computer, which they use for more than one year, turns off long enough, especially if it is installed on the operating system Windows. What is the reason for this behavior of personal a computera?

Why does the computer shut down for a long time

One of the reasons for the long shutdown a computerand maybe an operating system thathas been working on it for many years. During this time, a lot of software has accumulated, some of the applications are automatically registered in the startup. Each time you turn on the PC, they are loaded with the operating system and remain running, regardless of whether you use them in the work or not. And when you turn off the system gives time to applications to complete the work without errors. And the more installed and running programs, the more time is spent turning off a computera. Fix the state of things and speed up the shutdown a computeror you can do this by selecting the "Run" command from the main menu, enter Msconfig there. Go to the "Startup" tab and remove the extra checkboxes, then click "OK." When you turn off a computerand the operating system completes the completion of allapplications. If the program does not respond, the system waits for a while, and then forcibly terminates its execution. If the wait time is large enough and there are a lot of hung applications, a computer terminates the work for a long time. Therefore, before shutting down, it is better to close all applications by yourself, and even better in the process of closing all unused programs. For example, a lot of programs do not close after clicking on the "X", but are minimized to the system tray. a computerand may also be due to errors in the registry. To fix this, install a special application, for example, Ccleaner, and use it to search and fix errors in the registry. This will enable your a computerwork and turn off faster. Also one of the reasons for the long shutdown of the PC may be the presence of a computermalicious programs. Most viruses can stay in the system for a long time and do not give themselves out, but some of them significantly hamper the work of both individual applications and the entire operating system.

Tip 5: Why does the computer reboot itself?

Part of the malfunction of a desktop computeris caused by improper operation of this device. Often there is a situation where the PC reboots for no apparent reason. This problem can be corrected without assistance.

Instructions

To find out the reason for the spontaneousrestart the computer, you must carefully observe this process. If no messages appear on the display, and the computer restarts after restarting, the cause may be overheating of any device.

Try to determine which equipmentcauses the computer to shutdown. Remove the left side of the chassis. Touch the bottom of the cooling cooler installed on the CPU. The second device should be checked by the video card. Turn on the computer and make sure that all the fans installed in the case work properly.

Install and run the program that displays thetemperature indicators of equipment. For these purposes, AIDA is perfect. After opening the main program window, go to the "Computer" menu and open the "Sensor" item. Look at the temperature of all the displayed devices. Find out which of them overheats and leads to the shutdown of the PC.

If the cause of the computer's auto-shutdown isoverheating of the CPU, replace the thermal grease on this unit and clean the fan with the radiator. In the case of a video card, it is necessary to clean the above elements on it or completely replace the cooling system of this board.

Quite often the reason for turning off the computeris a faulty power supply. It is quite difficult to repair this device on its own. Try to connect a block with similar characteristics to the PC and check the computer's efficiency.

The blue screen is most often due toInstall unsuitable drivers on certain devices. Most often it's a video card or a chipset. Install the original drivers supplied with the computer or its individual components. Often, BSOD can be observed when a hard disk or motherboard is malfunctioning. In this situation, you need to replace faulty equipment.

If the problem is caused by a malfunctioning hard drivetry installing the operating system to another drive. Connect both hard drives and copy the information you need to a working media. Do not store important files on a known faulty hard drive.
