Help on win XP rebooting please help

[Naynesh]

The Computer in Windows XP cannot shut down, when i press the shut down buton from the start menu, or when i press the power button. Instead of shutting down it restarts the computer everytime. SO whenever I need to power off the computer in XP mode I need to switch off my UPS. Because of manually powering off the CPU by the UPS, when I start the computer again it shows the BIOS setting automatically , saying that the CPU was not shutt off properly last time, this is the safe mode so that you can correct errors.
Im using Win Xp prefess version on Asus motherboard , P4 1.7.
I have a dual operating sys Xp and 98 , the shuting down process works fine in win 98.

You need to make sure you visit Windows Update often to make sure you have the latest patches for Windows XP. Their is a patch that has to do with a UPS issue, although it might not fix your specific problem. More info at the bottom.

If you shut down your Windows XP-based computer, your computer may restart instead of shutting down. The computer may also restart unexpectedly while you are using the computer to perform certain tasks. A error message on a blue screen may appear when the computer restarts.

This behavior may occur if Windows throws a fatal error during a typical operation or during the shutdown process. By default, the computer is configured to automatically restart during a fatal error. To view this setting, right-click My Computer, click the Advanced tab, click Settings under Startup and Recovery, and then view the Automatically restart check box under System Failure. If the Automatically restart check box is selected, Windows automatically restarts if the computer stops unexpectedly.

If your computer constantly restarts if you are using the computer or if you are trying to shut down the computer, click to clear the Automatically restart check box. If you clear this check box, you receive an error message if a stop error occurs. This error message may describe the cause of the critical stop error. You can also review the system log in Event Viewer to view the critical stop error that occurs when the computer restarts.

By default, the Automatically restart check box is selected so that you can continue to use the computer if a critical stop error occurs. Microsoft Services start during the startup process before you log on; therefore the computer is functional after it restarts. If the computer stops because of a critical stop error, you lose all functionality including the remote access functionality. After the computer restarts, you can investigate the reason for the stop error.
