I've been having a nightmare with my machine for many more months than I would like to recall. The machine is an athlon64 3200+, Abit AV8, 1gig crucial ballistix. audigy 2 and an nvidia 6800 GT. I've tested the memory, thats all fine but still occassionally my machine will lock up with a BSOD. If anyone could shed some light one what is causing this i would be most appreciative. The only driver on my system that isnt quite up to date (because for some reason it wont detect my soundcard properly) is the audigy 2 driver. I've attached the dumps to see if you can get anything out of them Thank in advance.
