Vista - Shutdown & restart problems

Using Vista Home Premium on a Dell XPS420, installed by manufacturer. No
problems until I installed SP1 a few days ago. Since then, computer hangs
up on shutdown or restart. I have to manually shut it down. Anyone have
any thoughts?
TIA!!

If you believe the problem is caused by SP1 -
