Solve winxp shutdown but restart failure

In addition to the slow shutdown speed, shutdown failures rarely occur under normal circumstances. But sometimes it is inexplicably restarted when Windows XP is turned off. This failure is the most common failure in the Windows XP operating system shutdown failure. The cause of this failure may be due to the following reasons:
System Settings
Windows XP defaults to automatically restart when there is an error in the system, so that when the user shuts down, if the system fails during the shutdown process The computer will restart. Turning this feature off often resolves the failure of an automatic restart.
Right click on the desktop “My Computer”, select “Properties> in the pop-up menu, pop-up "System Properties" window, click "“Advanced" tab, click &ldquo "Startup and Recovery" in the "Settings" button in the column, pop-up "Startup and Recovery" window. In the “System Failure” column, remove the checkmark before the “Automatically restart” option, and click the “OK” button.
Advanced Power Management
It is well known that shutdown is closely related to power management. The cause of shutdown failure is likely to be caused by poor power management.

If you are using "Enable Advanced Power Support" when the failure occurs, try to cancel it. If the failure occurs, you are using the cancel "advanced power support" and try to enable it. Will be solved.
USB Devices
Now, when USB devices are popular, what U disk, mouse, keyboard, modem, etc. are all available. As everyone knows, these USB devices are often the main culprit for shutdown failures. When a shutdown turns into a reboot failure, if you have a USB device attached to your computer, please unplug it and try again. If you are sure that the USB device is faulty, it is best to replace the device or connect it. An external USB Hub connects the USB device to the USB Hub instead of directly to the USB port on the motherboard.
