With a heavy load on the processor or insufficient ventilation, its temperature rises and, exceeding the critical one, gives the command to force the computer to shutdown.
You can avoid overheating by knowing the current CPU temperature.
The simplest, but the right way to find outCPU temperature? See the necessary information in the BIOS. To enter the BIOS, hold the DELETE key while turning on the computer. A window with tabs will appear where you need to find the system partition. Manufacturers of motherboards can head it in different ways, but you should be guided by the word? SYSTEM ?. In this section, you will clearly see a line with CPU temperature readings. Remember that you can move in the BIOS only using the arrow keys, because the mouse will not work.
Another variant ? Use one of the programs that allows you to directly monitor and even control CPU temperature, fan speed, etc. from Windows directly. These programs include SpeedFan, Core Temp, Everest, NextSensor and others. Having installed one of them, you will receive information about the observations of your system. Unfortunately, not all such programs provide accurate information, and experts advise nevertheless to focus on the BIOS readings.
