My computer won t turn on and won t shut down

It's obviously a system problem, reinstall it.

System issues, reinstall.

It is possible that there is a problem with the boot option set in the hardware BIOS.

Solution: Press the DEL key on boot to enter the host BIOS settings, find the boot tab, and change the settings to boot from the hard disk (boot

FromHardDisk(HDD)), save and exit, start again and everything is OK!

You can try it on the 3rd floor.

I have 10 years of experience.

1Unless there is a virus or something, normal operation will not make the computer unable to boot.

2. It is possible that the system has broken the system program, or other reasons such as illegal operation have caused the system to fail.

3 It is likely that there is a problem with the power supply, because I have not had your situation for more than 10 years, (there is no response when the machine is turned on).

4 The reason is very noisy and slow, but your problem is mainly that the boot button on the third point is invalid.

I feel like you should value the third point, so go look for it and take a look at it for a while.

Supplement,5 This you can upgrade the mold in the BIOS to look at it.,But you don't even have a response to the boot button, so it's recommended that you still focus on point 3.。

Hope it helps:

Can it turn on normally after auto shutdown?

If it can be turned on normally, then it should be normal for you in this situation, and it belongs to the self-protection function of the system, because the motherboard BIOS settings have an automatic power-off protection function, that is, when the computer is overloaded or encounters other situations that damage the CPU or system.

In addition, this information will be fed back to the motherboard chip in time to react, and since the BIOS has set up this protection function, in order to protect the CPU from it.

damage, the system will automatically lose power.

It is estimated that your computer should clean up the dust or the fan is not running very well, which is generally caused by the CPU overheating or CPU negative due to the long-term operation of the computer.

Occurs in case of overload. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function.

If that's the case, rule out the heat dissipation problem!

If the computer cannot be turned on normally after power failure, it is estimated that there is a problem with the hardware or system files.

First, use the replacement method to troubleshoot the hardware problem (mainly check the motherboard and power supply).

After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

What should I do if my computer can't be turned off?

Problem analysis: There are many reasons for the failure to shut down normally, such as running many programs before shutdown that have not been closed, resulting in delayed execution of shutdown commands or system feign death, or the shutdown program conflicts or is damaged by other programs, or virus infection, or hard disk or memory problems, etc.

Solution: 1. Forced shutdown: If the current shutdown cannot be normal, you can press and hold the power switch of the host until the power indicator of the host goes out.

2. Before shutting down the computer next time, you must close other running programs normally.

3. If the above operations still can't solve the problem, press F8 to enter the safe mode after booting, run 360 Security Guard, and combine 360 antivirus or similar security software to comprehensively check and kill Trojans and viruses.

4. If the above operations are invalid, reinstall the system to eliminate hardware problems.
