How does the computer suddenly shut down, what happens to the computer suddenly shuts down

There are many reasons for the shutdown, it is recommended that you go to the motherboard BIOS settings interface to check whether the temperature control automatic shutdown function is enabled, you can turn it off or turn the temperature of the temperature control higher to prevent it from automatically shutting down. In general, it is caused by the high temperature of the CPU, so it is recommended that you disassemble the chassis and monitor the CPU fan.

Check to see if your voltage was unstable at the time, or if there was a problem with your power supply. Recommendations:

Check the power wiring and power supply;

2. Change a power socket;

3. Whether the computer power supply fan is rotating.

4. Antivirus. Virus Chinese name: **wave.

English name of the virus:

Virus size: 15,872 bytes.

Virus type: Worm.

Temp program, monitor the temperature of the CPU, more than 80 degrees Celsius, the possibility of turning off the machine at any time.

Hello. Your situation is generally caused by the following reasons:

1 The computer system is poisoned or infected with malware.

2 CPU Fan Bad CPU Temperature Too High, Overheating Protection.

3 The power supply is bad, or new hardware has been added, and the power supply is insufficient.

4 The fan of the graphics card or graphics card is broken.

5 The motherboard is broken, and the motherboard core is overheating.

Solution: 1 Check whether the antivirus software has killed the virus, you can determine, whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use a combination of antivirus software with Mu code, or if it doesn't work, reinstall or restore the system, you can solve it.

2 **Master Lu software, test the temperature of each hardware of the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and change the CPU fan. About 30 -100 yuan.

3 If the computer has a discrete graphics card, the power supply is not enough, then you can only change to a higher power power supply, the power supply has been used for a long time, unstable, then you also need to change the power supply to test.

4 Shut down, touch the south bridge, north and brother bridge chips of the motherboard with your hands, and the graphics card chip, if it is very hot, it is likely to be broken and needs to be repaired.

Please start with what I said above and go for a check.

Hope it helps you, don't understand hi me!

My notebook too, no problem from the beginning!

Depending on whether it is a laptop or a desktop, the situation is different, and it is difficult to analyze.

1. It is very likely that the voltage is unstable! I used to be at home (my house is in the countryside) and I couldn't turn on the phone at night.

2. There is also the possibility of poor power contact.

3. Power supply or CPU heat dissipation is not possible.

The automatic shutdown of the computer is mainly caused by the following reasons:

1.Poor heat dissipation. The system overheats due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, which will lead to the automatic shutdown of the computer, and the CPU temperature will be high.

Also, be sure to apply silicone grease, and not more or less, just apply a thin layer on the surface of the CPU. Dust it off often. The CPU's mesh fan is critical to the CPU's heat dissipation.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, check whether the memory is plugged into the motherboard.

3.Power issues. The insufficient power supply of the power supply is also an important factor that causes the computer to automatically shut down, and the voltage is unstable and easy to cause the computer to shut down automatically.

4.Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down.

If you are using Windows

2000 or Windows

XP system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

The voltage in your house is too low, I used to be like this, the computer can't be turned on, and the sparks will spark as soon as the power is turned on, so I changed the power supply and bought a voltage regulator.

Then it must be a voltage problem, which was the same in my house before.

The computer suddenly shuts down and restarts.

Later, I installed a transformer in the house and it was fine.
