Most of the reasons for the automatic shutdown of the computer can be divided into two types: software and mechanical. To identify the cause of this PC behavior, you need to follow a few simple steps.
Instructions
Step 1
It happens that the computer just shuts down or restarts. Check the temperature of critical equipment installed in the personal computer. The following devices overheat most often: video card, central processor, chipset. Download and install Everest or the modern version of AIDA. Start the selected software.
Step 2
Open the "Computer" menu, the icon of which is located in the left column. Select "Sensor". Wait while the program scans the hardware. Study the information provided. The temperature of the video card and processor should not exceed 60 ° C. Start a "heavy" graphics program or game. After 5-10 minutes, roll it up and look at the readings of the sensors again.
Step 3
Check that the power supply is working properly. The easiest option is to replace this device with a similar one for a while. Be sure to remember what kind of equipment was connected to the unit. Pay particular attention to the system board of your computer. Usually, two groups of cables are connected to it.
Step 4
If you experience a blue screen while shutting down your computer, check the drivers for the installed devices. In order not to reinstall absolutely all drivers, try to identify the hardware that is not working correctly. To do this, enter the error code into the search bar of your browser. It is usually presented in the form of several combinations of characters located under the Technical information field.
Step 5
If you could not determine what kind of device is giving the error, reinstall the drivers for the following devices: video card, central processing unit (chipset). Pay special attention to this point if you are working with a laptop. The installation of drivers must be performed in a specific sequence in cases where there are two video adapters in the computer. Install the chipset drivers first and reboot the mobile PC. Install the video card drivers last. Use only original programs downloaded from the websites of the manufacturers of a particular device.
Step 6
Sometimes a spontaneous shutdown of the computer can be a consequence of the operation of certain programs and services. Open the "Control Panel" and go to the "Power Options" menu. In the "Put the computer into sleep mode" column, select "Never". Open Advanced Power Options and expand the Sleep submenu. In the Hibernation After column, also select the Never option.
Step 7
Check active programs. The popular utorrent download manager is endowed with the function of shutting down the computer after the download is complete. Disable or remove unused programs.
