My computer always shuts down, I don t know what s going on

Viruses in the computer are very common, as long as you are connected to the Internet, you may be poisoned at any time!

Listen to you, since you have a virus, then use antivirus software, preferably Kaspersky, update the virus database, and then kill the virus completely! Make sure your computer is in a non-toxic environment!

You say that the computer boot problem, this is likely to be a hardware problem, disassemble the case, clean the dust from the fan on the CPU and other places, unplug the graphics card and memory, and wipe the gold finger part well!!

Again, it's summer, and the temperature is high! Don't leave your computer running at high speed for a long time, just let it rest every once in a while!!

Obviously, this problem is on your CPU, if the cup is overheated, it will cause you such a problem, your CPU fan may not rotate or it is too slow, you can turn it on and see, or the heat conduction is not good, hurry up and change the fan, otherwise, it will burn your CPU. (You can look at the temperature of your cup when you turn it on).

You see if your CPU temperature is too high, if your motherboard has a CPU health option, you can go directly to the BIOS to see, if your motherboard does not have a CPU health option, you can use software, Everest is a very powerful software.

Unplug the power supply first to see if it is a problem caused by overheating, unplug the memory, wipe the gold finger, clean up the dust in the case, and use 360 antivirus to clean up the malware.

To kill the virus completely, you can use Rising or Kaspersky's professional antivirus software, but you can't reinstall the system

1) Whether the hardware is installed completely, loose, deformed, or broken column causes the system to self-protect and shut down, pay special attention to the placement of graphics cards and memory modules.

2) Whether the CPU is overheated, whether the heat dissipation effect of the fan on the CPU meets the requirements of the body, and whether the chip overheating causes the machine to self-protect and automatically shut down. The graphics card is overheating and the graphics card fan with the fan may be damaged!

3) Whether the power supply is normal, whether the power supply capacitor is protruding, if it is protruding, change it, whether the voltage meets the power supply requirements, insufficient power supply and capacitor damage also cause the machine to suddenly power off and cause shutdown.

4) Caused by viruses, Trojans and viruses cause machine program errors or CPU occupancy is too high, affecting the normal operation of the machine and causing self-protection shutdown. It is recommended to install the system in safe mode and then repartition the installation system.

Generally speaking, it is a shutdown caused by hardware, and most viruses cause the machine to restart more! Automatic shutdown is a self-protection program of the computer, so you don't have to worry too much about the machine from being seriously damaged! Try the above methods, if it doesn't work, call a computer repair to check it thoroughly.

It feels like it has something to do with your CPU fan, you reinstall the fan, if it still doesn't work, change the fan, and if your machine has been bought for a long time, it is recommended to change the coin cell battery of the motherboard.

The computer shuts down automatically, why? How to solve it?

It is likely that the CPU fan is faulty, and if the heat dissipation effect cannot be achieved, the CPU will burn off, so the motherboard will automatically shut down when it detects that the CPU temperature is too high.
