The computer has long been not only a working tool, but also a means of communication, and a favorite type of recreation for many owners.
It is clear that the incorrect operation of this device leads to material losses, and to a spoiled mood.
The computer restarts when it is turned on
Usually restart immediately after power onIs caused by problems with the power supply - it may be out of order or its power is not enough to provide energy to all components. The technical documentation and the manufacturers' websites indicate how much power the device uses in normal mode and at peak loads. Check the operation of the computer with a new power supply, the nominal power of which is enough to supply all the components of the system unit.
When the computer is turned on before the operating system is loadedThe system starts the POST - firmware self-test, which evaluates the status of devices in the system unit. If the test went well, the BIOS reports this by a short single beep and instructs the operating system to boot. The incorrect operation of any of the devices is reported by a combination of long and short signals. If your computer reboots immediately after power-on, try using the POST decryption table for your motherboard. This way you will be able to identify the faulty device.
If the "beeps" point to RAM, the siteManufacturer of the motherboard, check if your motherboard supports this device. If so, carefully remove the RAM modules from the slots and wipe the contacts with an ordinary eraser. Insert the modules one at a time and check the operation of the computer to determine the faulty RAM card if there is a problem in it. If the module is one, insert it one by one into different slots. Be careful and careful not to damage the textolite. If possible, check the operation of a computer with known good memory.
In the same way, check the operation of the video card, if POST signals its failure. Clean contacts from your card and ask for a different fee for a while from acquaintances, if this operation did not help.
Another source of trouble can be a seeded battery that feeds the ROM chip on the motherboard. Replace it and check the computer.
The computer restarts during operation
A very common cause of reboots,Except for the faulty power supply unit, is the overheating of the components. Check the temperature of the processor, the north and south bridge, the video card using special programs (AIDA, EVEREST) or tactile, immediately after shutdown. Disconnect the computer from the network, remove the side panel of the system unit and blow it out with a vacuum cleaner to blow out.
It is possible that the thermal paste on the radiator has driedProcessor. If you are confident in your abilities, remove the radiator, clean it with alcohol and its surface from the old paste. Then apply to the cleaned radiator a very small amount (literally from the match head) of fresh thermal grease and spread it over the surface evenly. When installing the heat sink, make sure that it rises smoothly, without distortion, otherwise the processor may fail due to uneven overheating. If you doubt that everything will be done correctly, it is better to contact the customer service.
The cause of reboots can be softwareOr incorrectly installed drivers. Right-click on the "My Computer" icon, select the "Properties" option, go to the "Advanced" tab and click "Options" in the "Download and Restore" section. In the "System Failure" section, uncheck the box "Perform automatic reboot". Now, in case of a critical situation, the computer will not reboot, but go to the blue screen of death with an error message. On the Microsoft support website for the error code, you can find its cause.
