I think I found the problem I was having with a Gateway 2000 GP5-200 desktop computer. It would randomly freeze or drop into STOP errors. I started looking at the motherboard and found a voltage regulator attached to a beefy heatsink. Even with that, it still got too hot to touch for very long. If you look at the URL below, note the electrolytic caps sandwiched in between the two major fins on the heatsink. That can't be a great idea.
Last I looked it had been up for over five hours now. I guess Gateway shouldn't have been so stingy with their idea to put another fan in place...maybe that's why I've never seen another one of these?

Sorry for the cross-posting. It seemed like this topic would fit well in both groups. The IP is dynamic but should be relatively stable. I lost my DynDNS account (after six years, they killed it for 30 days of my not signing in!) and am working to get it back.
