Why does the computer automatically prompt me to restart?

First of all, check whether it is caused by overheating, if not, then whether your QQ speed car and game are overloaded, and finally check whether your power supply is stable.

Go to the BIOS to check if the over-temperature protection is set.

That's pretty much it.

1.Enter msconfig in the start menu run, remove all (except ctfmon) checkmarks in the startup and try to save and restart (you can also speed up the startup), generally you run too much, or file conflicts.

Install 360 security guard, boot has been pressing F8 to enter the safe mode to kill, now nine out of ten poisons on the Internet are Trojans, so the antivirus software can not find the virus, it is recommended to install 360 kill.

2。If the heat dissipation is not good, reinstall the CPU heatsink, you can have poor contact, and you can replace the CPU fan.

3。Reseat the graphics card and memory card, the main thing is to clean the dust near the CPU and memory, which is the easiest way.

4.Or try a different power supply (check your electricity usage, sometimes the voltage is not stable).

5.Your computer capacitor may be bursting, see if there are a few capacitors near your computer CPU (the capacitor erected like a small bucket) is bulging, the normal should be flat, find a few capacitors of the same model to weld and replace them or go to the repair department to repair them.

Start normally, if you can't get in, enter the safe mode directly.

Poisoning or CPU fan does not get hot.

Or there is ash in the memory.

Loose or. Blue Bridge, White Bridge.

That's the case if there's a problem.

However, it is generally the CPU fan that does not heat up.

Or poisoning. That's right, there's more.

Sometimes there is a problem with the power supply.

At that time, there will be no problems with the general power supply.

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.

4: Software factor. 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 protection 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 fails, or the voltage fluctuates greatly, add AC regulated power supply.

8: No, it is recommended to disinfect in safe mode, and it is not possible to disconnect the network and reinstall the system 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

There are many reasons for viruses, careless operation, etc., you can find fault with the hardware first, add silica gel to the CPU first, and then fully disinfect the virus. If it's hardware, it's a big problem.

The occasional computer error will cause a reboot!!

If it doesn't show up often, ignore it!!

I'm also here once in a few months! Normal thing!! As long as it doesn't show up often!

If it often occurs, it is recommended to redo the system!!
