Interpretation of the five problems that cause the computer to shut down

First, the power supply setting error

The power supply is the energy center of the computer. The correct configuration of the power supply is the first culprit leading to the shutdown failure. In this regard, we can press DEL to enter the BIOS at boot time, then select power management "Power Management Setup", set "ACPI Function" to "Enabled", and set "PM Control By APM" to "YES".

Go to the Control Panel to turn on the power option, select the "Enable Advanced Power Management" item in the "Advanced Power Management" tab, and finally run "regedit" to open the Registry Editor, select HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft \\Windows NT\\CurrentVersion\\Winlogon, set the PowerdownAfterShutdown value on the right to 1. After you finish these settings, restart your computer (know: what if the computer is slow down?).

Second, the sound file is damaged when exiting

Some users have enabled the sound scheme, so that when the power is turned on, the power is turned off, etc., there will be music sounds accompanying the ear. This is also a culprit in the shutdown failure, that is, the sound file is damaged when the computer is turned off. In this regard, we can go to the control panel, open the "Sound and Audio Devices" item, switch to the "Sounds" tab, then set the "Sound Scheme" to "Silent", or "Exit Windows" in "Program Events" The sound is set to "None".

Three, some software is working

If your computer is turned off normally, but after installing some application software, there is an error that cannot be shut down. This is probably because The system files were modified when the software was installed. At this time, we do not prevent the software from being uninstalled first, or use Windows XP's system restore function to restore the system state to an earlier state. If the problem is solved, then the software is problematic. This situation is especially common on various beta software (know know: let the computer shut down automatically).

Fourth, the resident program does not exit

Sometimes, the "shutdown" command is executed, but the computer responds slowly, but as long as you can wait patiently for a while, eventually Can be successfully closed, and the occurrence of this situation is random, not every time. At this point you need to check if there are other resident programs that are not closed. You can open the Task Manager, view the processes in the "Processes" tab, which can be forced to close, or you can hold down the Ctrl key and click on the "Shutdown" menu in the "Task Manager" The "shutdown" command can be (know know: what should the computer automatically shut down?).

Five, automatic shutdown or restart

This situation is believed to have been encountered by many people, this can be first checked from the software. Install a virus patch that causes the system to shut down for 1 minute, such as shock wave, shock wave, etc. Secondly, open the system properties window, click the “Settings” button in “Startup and Recovery” in the “Advanced” tab, and “System Failure” The Auto Restart item is canceled. In addition, the automatic shutdown may also be a heat dissipation problem. Do not open the chassis and observe whether the CPU fan rotates normally. If the speed is slow or does not turn, then the fan needs to be replaced.

After the above processing, I believe that you have a comprehensive understanding of the cause of the shutdown failure.
