My machine has problems. it runs fine 90% of the time. But just this week, when I am playing Diablo II, the machine restarted randomly a few times. Now it restarts around 5 minutes into the game. But when the game is not open it runs fine. Now, i've head this before with Warcraft 3 in Janurary. I had a crappy mobo DFC, whcih I thought was the problem. I was running XP. I then got a Gigabyte mobo, a different hard drive, and installed Windows 2000 Prof. The problem disappeared, only to resurface now. I've made no changes to the PC configuration since Janurary and it's been running problem free since Janurary. On a side note, certifications are pointless and stupid. I have Microsoft 70-210, which means I should be able to take care of this crap, but I have no idea what to do, not to mention i don't have a 2000 CD. As it stands, i'm trying to install XP, but I was wondering if anyone else had this occur and if so was there an easy solution.
