The shutdown can t be turned off, and the power supply is built in What to do. I tried all sorts of

1. When the computer cannot be shut down, it is very likely that our computer has been invaded by a virus, which is why we need to open the relevant antivirus software program. After 3 5 minutes of virus scanning, the problem will be solved according to the prompts.

2. If the shutdown still fails, use the task manager to check the running program to see which program failed to close successfully, causing the computer to fail to shut down normally. End programs that can't close on their own with Task Manager.

3. Use PC Manager to try to clean up the system junk and close some infrequently used boot add-ons, because some programs have been running automatically at boot, and this software is not often enabled. If you have too much software running, your computer may not be able to shut down.

4. Open the control panel - system, check whether there is a question mark or a device marked with a yellow warning in the device manager, if there is an attempt to reinstall the corresponding driver and follow the prompts, you can generally solve the problem.

It should be a system problem! Reload the system and take a look!

This is usually due to the motherboard's "wake up" function, and then the system's "auto-restart" function.

Solution: 1Turn off the motherboard's wake-on-net. When the ATX power supply is unstable, the suspect key generates a misaligned pulse signal at the moment of performing the "shutdown" action, which causes the machine to restart when it is shut down.

Boot the DEL button to enter the BIOS settings interface, and select the "PWOER."

2. Turn off the automatic restart function of the system. By default, Windows XP automatically restarts when there is an error in the system, so that when the user shuts down, the computer will be restarted if there is an error in the system during the shutdown process. Disabling this feature often resolves the problem of auto-restart.

In my computer properties Advanced, in"Boot and failback"Click on the sensitive slide settings on the left, remove the checkmark before the "Auto Restart" precedent, and click the "OK" button.

The number one computer killer is forced shutdown - whether it is a shutdown or a crash, or unplugging yourself, which makes the computer lose power instantly. It can damage data or computer hardware.

1. Hurt the hard disk, this is the most important thing, because of the sudden forced shutdown, the hard disk head can not be reset, the next time Pi Sui boots up and re-seeks, it is easy to damage the hard disk repeatedly;

2. The ongoing operation and unsaved data of the office will be lost, sometimes causing the system to be abnormal.

The CPU suddenly stops at a serious hazard to the silicon chips in the work. The worst thing is the hard drive, which is likely to lose data and the head is also very easy to break. This will seriously shorten the life of the machine, so it is recommended not to mess around!
