Well that's good news at least.

Sounds like it. Any unusual programs installed? Hardware monitoring tools? DirectX 9? (grasping at straws here).
Although formatting the HD is an option
If you do, install Win9x on a small partition at the front of the drive. Then when you re-install XP, choose "new install" instead of upgrade, and let XP set up a Dual-Boot for you. It's fairly painless, and gives you the luxury of a fall-back OS for titles that "Hate NT".
