Came home today and saw the blue screen of death. That's the first time I've seen it in quite a while. When I tried to reboot, I couldn't even get to the BIOS screen. I deduced it was probably the memory, since I was working with it yesterday. Reseating the memory didn't work, but I finally isolated one of the DIMMs that was bad. So now I'm sitting at 6 gig. I'm not actually sure if it was a new DIMM or old one that is bad.
