The computer will automatically shut down when it enters the desktop, and the computer will automati

There are several kinds of questions, and I will go down in order of the closest cause1The capacitance of the computer motherboard is bad, and the CPU cannot dissipate heat due to the fact that the CPU does not rotate due to the fact that the CPU does not rotate 3There is a problem with the power supply in the computer, 4 systems are installed more or system problems, 5 computers have viruses installed with 360 and Rising fire prevention, etc.

Check to see if it's lost or damaged.

The md5 should be 40976499c7e53cb02f35e0d07205f317 (xp) (may vary depending on the system).

If it's not for this guarantee that you're in trouble.

If you replace it with the correct one, it won't work.

That's 100% a virus.

It is recommended to enter the PE to format the C disk (it should be very good for the virus now, even if you are only infected with one, it is estimated that you will have to reinstall the system or format the C disk or do ghost to the whole system).

Then it is recommended to reinstall the system (for people who have not ghosted the C drive before) or ghost restore the C disk after formatting (for those who have ghosted the C drive before).

The virus in the NB is up.。。 It's useless to kill. Reload the lower C drive. Then antivirus.

Medium virus ...Let's reinstall the system.

The socket behind the host should be plugged in, the wiring is too loose, if it doesn't work as I say, call the person who repairs the computer to repair it.

Or plug the hardware back in and check it in again, and then install the system.

Your system may be broken, you can restore it with one click, or you can do it for a while. That's it!

CPU overheating: Just put on a little thermal grease.

Wipe the CPU and fan dry first, and then apply silicone grease.

Poor contact will not turn on the machine. You try to reinstall the system.

Confirm that the temperature in the chassis is high, the key is the temperature of the CPU and the temperature of the power supply (there is too much dust in the power supply and the fan does not turn), replace the BIOS battery, and then remove the memory module, hard disk cable, optical drive cable, graphics card, sound card, network card, etc. from the motherboard, and carefully clean up the dust. Use an eraser to remove the oxide from the gold finger on all hardware, and you have to wipe hard to get rid of it. Then install the CPU, memory module, and graphics card, just install these three things first, and try to turn it on.

If it is not normal, the motherboard or power supply is wrong, if it is normal, then install the hard disk cable, optical drive cable, sound card and network card in turn, and then turn on the computer after each installation. You can determine which hardware is the fault.

Is the contact not good, find someone to take a look.
