To shut down a frozen computer. Press and hold the shut down button for 15 or so seconds.

Is there anything in the error logs?

Have you try setting the cmos settings back to default.

There is a third-party patch for this error, I had to use it some time ago. Sorry I can post a link as I don't know it and it was on my old PC.

run the windows updates

With old 98 PCs this was a common problem and some of the suggestions above are valid, but not for XP pro.
