Why won t my computer shut down

Press Ctrl+Alt+Del first to see if the shutdown is useful.

If it doesn't work, just press and hold the button that turns on the phone, and it will turn off if you press it more.

First look at the power options in the control panel, set it in advanced, and if it doesn't work, go to the power options in the BIO and reset it.

There is an error in the power item in coms, please reset it.

Dig. My friend's computer is the same as yours. Stuffy.

Maybe you default to restarting.

It is possible that Dianxiang leaks multiple accounts to log in slowly, enter other accounts to take the account, and cancel the account after saving the data.

Then select Shut Down under the current account.

1. There is a defect in the automatic program in the system file. In order to confirm whether this is the cause, the following experiments can be performed. In Start Run enter:

rundll32user, exe, exitwindows to see if it can shut down normally. If you can shut down normally under this command, it means that the automatic program may have some kind of defect, if you are using win98 system, please run the SFC program, check the integrity of the system files and repair the files. If other systems are used, such as Winme, 2000, XP, file patching can also be done in the corresponding project.

If patching the file still doesn't solve the problem, you can only reinstall the system. If you run rundll32user or exe and exitwindows cannot shut down normally, it may be that some programs in the operating system are defective, and the solution is to patch the system or reinstall the system.

2. Viruses and some defective programs or system tasks may cause shutdown failure. The first option is to scan viruses and close all applications before shutting down the computer. Since some programs are loaded when the system starts, you can delete all the programs in the startup group, run the msconfig program to the startup group, and remove all the programs to see if there are any programs that affect the shutdown.

3. The compatibility between peripherals and drivers is not good, and it cannot respond to rapid shutdown. You can run msconfig, select Advanced in the General tab, and disable rapid shutdown in the window that opens. If you suspect that the peripherals are faulty, you can also uninstall the peripherals one by one to check them in order to find the affected peripherals.

4. If you set the use of sound files when closing windows, when the file is corrupted, it can also cause shutdown failure, please select "Exit Windows" in the sound event in the control panel, and set the sound to none.

5、When win98 automatically closes, it will display "Now you can safely shut down the computer",This content is done by the logos、Sys file in the windows directory,If this file is damaged,It can also cause it to not be able to shut down,Solution,Restore the file。

6. WinXP can not be automatically shut down after installation, if the above reasons are ruled out, it may be that the power options in the control panel are not set correctly, please check your settings to ensure that ACPI and APM can work normally. There are also incompatibilities between APM and WinXP in the motherboard system BIOS because it cannot be automatically shut down. Choosing to shut down turns into a reboot of the system, in which case you can only manually shut down.

The solution to the problem is to upgrade the motherboard's system BIOS to a new version.

1. The first reason: it is the reason for the advanced power management in the BIOS: the factor that causes the shutdown failure may be the failure caused by the poor support of the power management for the system.

Solution: Press Del to enter the BIOS, in the power management menu, look at "RME EventWake Up", whether the item is "Enable" (default), if so, please change it to "Disable".

2. The second reason: is the system setting factor: by default, in Windows XP, there will be no shutdown or automatic restart when there is an error in the system, so when the user shuts down, the system will restart the computer if there is an error during the shutdown process, and the function can be turned off to deal with the failure of automatic restart.

Solution: First, right-click "My Computer", select "Properties" in the right-click menu that appears, display the "System Properties" window, click the "Advanced" tab, then click the "Settings" button in the "Startup and Failback" column to display the "Startup and Failback" window, and finally delete the checkmark before the "Auto Restart" option in the "System Failure" column, and click the "OK" button.

3. The third reason: due to the Trojan virus in the computer, the Trojan destroys the system files, resulting in the shutdown or restart, Jianyi press the F8 key after booting, enter the safe mode, and carry out a full antivirus, if the antivirus is over, it still can't be solved, which can only be restored or reinstalled with one click.

4. The fourth reason: This is due to the damage of the B pole of a triode in the boot circuit of the motherboard, forming an open circuit, resulting in PSON, which cannot be grounded and has always been high, so it cannot be shut down, or a patch capacitor connected to PSON has a short circuit, resulting in the inability to pull PSON down, it has been a high level, and then it cannot be shut down and then restarted, which is a hardware problem, and the software and system have nothing to do with it. Solution:

It is to send the after-sales service to repair the boot circuit of the motherboard, or go to the repair shop to repair the boot circuit of the host, and let the repaired motherboard be replaced with a triode or a chip capacitor.
