If it ran smoothly for a while...what was the last thing you did?
How many of those eight fans do you have in that case?
Do you have a fan right on the CPU?
Where do you keep your case?
Sounds like a build up of heat somewhere....you've got some pretty hefty programs running.
You might run it without the cover for a while and see what happens.
I'm no Win2k expert, as we run NT....
Good luck to you, though...I know this is very frustrating.
