1, it is possible to have high-power equipment under the same power supply system as the computer, such as air conditioners, electric heaters, generators and other high-power equipment that may be used. The initial start-up of high-power equipment will cause the instantaneous voltage drop of commercial power, resulting in insufficient power supply for computers.
2. The other is that the power supply voltage is less than 220V V V. If the mains voltage jumps around 190V, it will easily lead to the automatic shutdown of the computer. This can be measured with an electric meter.
There is also the aging of the power transformer in the computer. Even if the commercial power is enough, the output voltage of the power transformer may be too low, resulting in insufficient power supply for the CPU.
4. There is a rusty or loose CPU power interface on the motherboard, resulting in poor contact.
5.CPU is too hot, because work will generate a lot of heat, which is unimaginable. In order to protect the CPU, the overheating protection function is designed, that is, when the CPU cannot dissipate heat, it will automatically stop working when it reaches a certain temperature. Then we first equipped the CPU with a radiator (CPU fan) to dissipate heat. If the fan stops rotating, or the speed does not reach the situation of continuously reducing the CPU temperature, it will automatically shut down. We can solve this problem by replacing the fan or cleaning the fan dust.
