Greetings all, first to introduce myself: /wave. Long time casual builder/tweaker, long time hardcore gamer. That aside, I built this new rig in June of this year and have been having the damndest time with it. System specs are as follows: Athlon 3200+ venice (not OC'ed) Tul AX480A (do not buy this board) 2 x 1GB PC3200 PNY Optima retail Radeon X1800XT WD 250gb HD etc. The rig BSOD's at least once per night, if not multiple times. It seems to be related to heat, but sometimes I'll wake up at 7am and the machine will BSOD within 4 minutes of bootup. Considering it can be as low as 55 F in my computer room in the morning, I don't know if it's heat or what. VERY RARELY, there will be a purple artifact on the blue screen. Most often the BSOD references ati3duag.dll, but lately it has been referencing system files like ntfs.sys and other things. I have attatched alot of minidumps below. I have run full diagnostics on every piece of hardware in my system. Nothing has failed, yet. I have run memtest extended tests for probably 36 hours total now. I was having deathly error #132s in my WoW gaming until about a month ago, so I was convinced it was a RAM error - BUT, those errors were fixed simply by adding .10v to the VDIMM and disabling my onboard soundcard (wtf?) So again, I'm not so sure it's the ram. Any help? here's another set of dumps Update: I just finished running Everest for 8 hours. Cpu maxxed out at 70 degrees C, but the machine remained stable for the duration of the test. So not heat?
