Hey Craig
Welcome to PCHF. We have a wonderful team of techs here, and I feel certain that we will be able to help you.
First of all, are you able to get into Safe Mode, or does it reboot there as well? Are you getting any kind of error message? Did a recovery CD come with the laptop? Can you tell us what if anything occured immediately before this began to happen? Are you running XP?
Looking forward to your reply,
TTFN
