Why does Windows XP shut down and restart

Q: I obviously chose to turn off the computer in Windows XP, but why is it restarted instead of shutting down directly?
A: This problem can be from the following I started to find a solution.
1. Set the BIOS correctly
If your computer is connected to the network or connected to a USB device, the BIOS settings may not be able to shut down properly. In general, the old motherboard is prone to such failures, and the network wake-up and USB wake-up options can be disabled in the BIOS.
2. Setting up power management
Shutdown is closely related to power management. Sometimes the power management option is set incorrectly, which will cause shutdown failure.
Click “Start →Setting →Control Panel →Power Options”, in the pop-up window, enable or disable "Advanced Power Support" as needed (if you are using the fault in the event of a failure) Enable “Advanced Power Support", try to cancel it, and vice versa.) This method in Windows 98 can often solve the shutdown problem caused by most power management. In addition, Windows XP provides the user with the operation when the power button is pressed. In the "Power Options" window, the "Advanced" tab will be set to “ when the computer power button is pressed. Turn off the power & rdquo;, and finally click & ldquo; OK & rdquo; quit.
3. Disable Fast Shutdown
Sometimes using the Quick Shutdown feature of Windows can also cause such shutdown problems. In Windows 98, you can solve it by entering Msconfig in the &startquo;running"run", open “system configuration utility", in the “Advanced” option, “ disable fast shutdown” Then restart your computer.
4. System Settings
When an error occurs in the system, Windows will automatically restart. Therefore, turning off this automatic restart function may solve the problem. Right click on the desktop "My Computer", select the "Properties" command, open the "System Properties" dialog box, switch to the "Advanced" tab, click “ Startup and Recovery&rdquo The "Settings" button in the column will uncheck the "Automatically restart" checkbox in the pop-up dialog box.
