Ok, I gotta try this forum as well.
So Im not alone with my problem, this is something quite common. (try 6800 problems with Google)
I've Gainward 6800LE 128MB and I've this massive crashing problem.
Anything with 3D-graphics crash after 0 to 15 minutes. This far I've found only one game - Arx Fatalis - that won't crash, but there's even some textures missing.
I've tried the following drivers with 4.53 4in1 Hyperions, but the problem stays.
Drivers with the 6800LE setup CD
Latest official drivers 61.67?
65.62.
Latest beta drivers I could find myself - 66.70.
Warhammer 40000: Dawn of War is what I've tested those drivers with...
3DMark03 runs fine 90% of time. Some times mid CPU Test (test #2 specially) it hangs for like 5-10 seconds and then skips those seconds forward...
3DMark05 gives corruption
CS: Source crashes after 5-30 minutes. Gives also corruption if I set 4x AA from game options. If I use forced 4x AA and 8x AF no visual glitches. Corruption
Warhammer 40000: Dawn of War crashes after 0-2 minutes.
Richard Burns Rally crashes after 0-30 seconds.
Panzers: Phase 1 crashes after 0-5 minutes.
And oh, I've changed motherboard twice, memories twice, processor once, power unit one, bought an UPS, changed all my hard drives, tried without sound card + CD/DVD-drive - these didn't help.
Formatted something like 6 to 7 times. Tried Windows 2000 Professional, Windows XP Professional with SP1 and SP2.
I've no viral software of anykind on my computer either...
Could someone help me out?
