Computer's Dead

My desktop is dead. Died right in the middle of a Fable session, too. Blank screen, no keyboard LEDs, won't boot. Yes, I've tried removing add-on cards, swapping RAM, etc. Dead. And I don't have money for a new one, and I don't want to put money into repairing this one, so my laptop's my only computer now, ignoring my PII fileserver.
