System:
AMD64 3200+ (764 pin)
Abit NF-8 v.2 motherboard
2 X 512MB Mushkin PC3500 memory
2 X 36 GB Sata Raptor Harddrives (RAID 0)
120GB Maxtor IDE drive (storage)
BFG Geforce 6800 GT OC
Plextor DVD RW

Case ambient temp <50 C
Video card temp after reboot 71 C

During gameplay (World of Warcraft, only game loaded), after 5-30 min.
video corrupts to gray and black checkerboard pattern, but I can still
hear sound. If left alone, computer will reboot to desktop. Event Viewer
shows no errors, however I do get under "System" Event 2, nvatabus,
usually 3 to 4 instances, all with the same time stamp.

I have run a video stability test and Aquamark 3D, both ran fine. I have
run 3 passes of Memtest86 with no errors. I have made sure the memory
was limited to 200MHZ to match the motherboard. I have tried different
DDR voltages from 2.65 to 2.8 with no difference. I have tried
allocating 3GB virtual memory instead of Windows managed- no difference.
Reloaded last released chipset drivers and latest video drivers.

I don't think it's a video card problem, but will swap cards to a
different computer to check playing the same game. I'd appreciate some
advice on how to proceed to narrow down the possibilities and isolate
the problem.

Thanks,
Fitz

That sounds like memory (ram),& it sounds like the tests run with microsoft
memory tester checking ram memory...Try downloading it & run the tests.
