My computer always restarts for no reason.,How can I solve it? Thank you

First of all, the antivirus makes sure that there is no soft fault in the system, and then looks for hardware.

1. The owner of the power supply can unplug the optical drive floppy drive to see if it is caused by insufficient power supply.

2: If there is a problem with its own voltage, you can use a multimeter to test the following.

3: The coms battery fails, which may also lead to this problem, so it is recommended to change the battery to try it.

4: Eliminate the above without any problem, use the replacement method for each piece of each piece.

5: If it really doesn't work, the landlord can dial the big Hongji after-sales service**.

It may be caused by overheating in the phase, the CPU has an overheating protection function, and the CPU will automatically restart when it reaches a certain temperature to ensure that the CPU is not burned.

It's XP's words. It could be a hardware or software conflict. You can do a system restore. If it doesn't work, fix the system.

There is a problem with the power supply, and the power supply is clear of the dust! I can't change it again.

Antivirus! Reinstall the system! Or change the power supply and memory.

It's best to see if the CPU fan turns or not.

Anti-virus, reinstall system.

It's really not possible to change the power supply.

The quickest way to do this is to find customer service.

One may be a Trojan horse, or a virus, and the other may be caused by unstable voltage.

See if it's a matter of voltage.

Or kill the poison!

It could be the power supply, or the memory, or the optical drive, etc.

Is it the case power switch that milk short circuit, the switch is really bad.

Heat Dissipation, Compatibility, Power, Memory, Viruses,

1.: Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.: Memory reasons. When the memory and the motherboard socket contact is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if it is down?

3.: Power supply issue. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

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 computer shuts down automatically for no reason.

5: Check whether the CPU is overheating and whether the CPU fan tray is stable, if it is broken.

Or it is unstable, can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the motherboard's automatic Baoling filial piety function will automatically shut down, and the CPU fan's screws are loose and early!

6: 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.

7: When the power supply of the host is faulty, or the voltage fluctuates greatly, you can add AC regulated power supply.

8: No, it is recommended to kill the virus in safe mode, and it is not possible to reinstall the system after disconnecting or disconnecting the network to eliminate system problems.

It's possible that there's too much dust on the fan.

Causes automatic shutdown.

It's normal to clean up the dust!
