Sorry to drag this issue up again but im still having this problem.. ( 2 months now and still no resolution )

If I try to play games such as

the suffering,
Far cry,
Ground control 2,

or benchmarking progs

3dmarks 2001 SE,
Fill rate test in 3dmarks 03'

I get crashes.
The crashes happen about 10 seconds in to the intro animations, when it loks up, freezes the sound and produces artifacts on screen. The artifacts vary from massive blurring, tearing, blank screens etc....
It occasionaly unfreezes for a few seconds then locks up again.

If Vsync is forced in all applications, this problem doesnt occur.

Ive tried ALL Availiable Nvidia drivers, ( now using whql's )
Flashed Bios on card,
Flashed Mobo,
Upgraded AGP driver,
Upgraded via 4 in 1's
tried DX 9.0 9.0b 9.0c,
removing all non essential components from my PC,
Underclocking GPU and CPU,
Overclocking GPU and CPU,
ensuring bios clock frequencies are identical for 2d/3d,
changing Agp aperture size,
toggling sideband adressing,
toggllng fast writes....etc etc etc

ive tried EVERYTHING I can think of and even spent a fotune on the phone to leadtek in the Netherlands. They said they dont know what the problem is....

If anyone has had this problem ( i saw a few others with similar problems but cant find the posts now ) and has fixed it, please let me know how =(

ATI is looking mighty fine right now.

Can you post your system specs? Please load DXDIAG and run DirectDraw and D3D tests.

I had some glitches in the beginning too and I really didn't want to format my system. I uninstalled Nvidia drivers, ran Driver Cleaner, downloaded DX9b. Installed, DX and then drivers 61.45's. Everything was very smooth from there on.

Hm.....I bought a Leadtek 6800GT, I have tried both the CD driver and 61.76, everything is running fine and smooth. With or without Vsyn
My config: 2.4C, Intel i865 mobo, 512m single channel
