What is the reason why the computer automatically restarts and crashes?

Power supply problems: low power supply, or power quality problems. My computer is the same, as long as the computer is on, I don't let people connect other power sources on the power strip. For example, when I go online, I plug a fan into the power strip and the computer shuts down immediately.

Turn on the fan and turn off the computer again. If you want to solve the problem completely, it is recommended that you change to a larger power supply, which is powerful. Preferably 300w.

Don't think about the power supply elsewhere on the computer.

Voltage issues. The CPU doesn't cool enough heat. High temperature.

These two aspects are the most straightforward.

It is advisable to check if the voltage in the place where you live is stable. There is also whether there is a problem with the host power supply.

Other than that. Whether the CPU fan is aging and needs to be replaced. You can also clean up the dust in the main unit. See if it works.

These points. Nabs. Not a big deal.

1。The voltage is unstable.

2。There is a problem with the power supply of the computer.

3。There is too much dust and not enough heat dissipation.

There is a problem.

The voltage problem depends on whether the voltage is unstable.

Check the power supply. The CPU temperature is too high, see if the CPU fan is a lot of dust.

Motherboard problem,This is a problem that I personally experienced, and you suddenly shut down and checked to finally determine that there is a problem with the motherboard.,Brother changed 6 motherboards in a month.。。。

Loss of system files or memory issues, as well as hard disks, motherboards, can all be possible.

The voltage is unstable, or the power of your power supply is too low.

It is possible that the power supply of the host is not very stable or the CPU temperature is too high.

If the CUP temperature is too high, the CPU fan will not be able to dissipate heat.

Power supply problemThe power supply power is small, and the elimination method solves this problem.

Power supply. Graphics. Such a problem will arise.

Maybe your power strip is not secure, you kicked it or something, and the power supply was disconnected, otherwise that's what they said.

There are generally the following reasons for this situation:

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

The fan should be broken, just replace it.

I guess there's a virus in my computer.
