This machine has been stable for over a year, and just in the past few months started throwing blue screen, sometimes 4 a day. Specs: Vista x64 Ultimate Abit AWD9 Max Motherboard E6600 @ 2.4ghz Corsair 2GB PC6400 Nvidia 8800 GTS Creative X-fi XtremeGamer 2x250gb Seagate HDs in RAID 0 Pioneer Blu-ray drive These blue screens can happen while watching a bluray movie, while browsing through some folders in explorer, or sitting idle. They didn't used to happen. I have the latest sound and video drivers, as well as the latest BIOS for my motherboard. I can pass several passes of memtest 86, but I've encountered an error in less than 2 minutes in Prime95 on the mixed (max heat, max power consumption) mode. Anyway, here are some dump files, they always name a different process as the culprit, and I don't really understand how to interpret them, so maybe you guys do. ETA: Prime95 errored out in less than a minute when I ran the 3rd test (tests mostly RAM.) So is it possible that my good ram has gone bad over time?
