You can try shutting down in safe mode, if it works ok there, you know you've probably got some software or driver locking it up before shutdown.

Open up Power Options in the Control Panel. Look for an APM tab, if it's there open it and check "Enable Advanced Power Management Support". If you don't have that tab you'll need to enable APM in your bios.
That's solved the problem for me on a friend's XP Pro computer.
