Why does my computer power itself out?

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated, whether the CPU fan rack is stable, if it is broken or unstable, the CPU fan cannot be suppressed, the CPU fan heat dissipation capacity is insufficient, the CPU temperature is too high, and the automatic protection function of the motherboard will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to kill the virus in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

It may be a heat dissipation problem, the CPU temperature is higher than the set dangerous value, it will automatically shut down, and the kind of fake notebook with desktop CPU often has problems with heat dissipation.

It is also possible that the power supply is not good.

Is it an automatic restart?

If it's an auto-restart, set question 2Hardware Conflict 3Hard Disk Problem 4The temperature is too high 5Virus.

Considering that you are an all-in-one computer, heat dissipation is a major problem @@

A: Whether the mains power is normal.

B: Is there a problem with the power supply of the machine?

C: Is there any problem with the software?

There are a few temperature settings in d:coms that need to be checked.

You have to figure out what the factors are first, and then find a way to prescribe the right medicine, your own power outage is too general!

Running calculations are unstable.

2. The power supply is unstable.

3.Graphics card change.

Maybe the power of the power supply is too small to afford it, causing the power outage.

See if the voltage in your home is low?

My analysis may have the following points:

One is the heat dissipation problem, the heat dissipation is not good, and the instantaneous value of the CPU temperature is too high, which will cause the system to protect itself and lose power, it is recommended to check and replace the better radiator;

The second is memory problems, memory failure or incompatibility will also cause the computer to crash or the operating system to fail, power off and restart;

The third is the CPU problem, the poor contact of the CPU pins will lead to errors in some operation circuits, which will cause circuit power-off protection;

Fourth, the hard disk problem, the hardware damage of the hard disk will also lead to the automatic power failure of the computer;

Fifth, the power supply problem, the power supply is overloaded, or the component failure will also lead to the failure to turn on, or the power failure phenomenon after starting;

I hope that Brother Ji Ji will check and check well, there is no problem in the world that cannot be solved, don't be anxious, hehe

How harmful is the sudden power failure in the use of the computer?
