gainward 8800gtx probs

[batchie]

just recently was having problems with card crashing out in GRAW2 (running vista prem home 32) nvidia driver not responding issues etc, after about 3 to 4 attemps trying to run the game started getting squiqly lines over the monitor and pc rebooting.I unistalled vista done fresh install to elliminate driver issues bit it still crashed or frooze my system when playing any 3d application's.
Just to eliminate vista i reinstalled xp pro,but suffered the same issues as above when running games etc,thinking the card was knackered i tried it in my sons pc (Asus P5B Deluxe, e6600,2gig gskill ) at at the moment works great all games play fine.
Would trying to force GRAW2 to play have mucked any other hardware and not the card (ie what factors beside the 8800gtx enable the card to run).
I brought a new power supply corsair 620,q6600go,and 4 gig of gskill 2x2gig to
see if any of these factors might have caused issues but still having problems running 3d applications,the only thing i havn't replaced is my asus comando mobo running 1501 bios.

Have a fiddle with PCIe speed in the BIOS, try it at 110Mhz

Also have a look at cooling, maybe the card is overheating in your case?

I was getting some tearing in GRAW2 with my GTX. It managed to pin it down to V-sync.

There is no V-sync setting in GRAW2 so I set up a profile (in nVidia settings) for the game forcing V-sync every time GRAW2 runs. Runs fine now.

Doesn't sound like exactly the same issue but might be worth a try.

EDIT: Re-reading your post I see you have this issue on other games but not when paired to another motherboard. As Dutch said, i'd try the PCIe speed. If not, then it could be heat or power supply issue.

Run GRAW2 whilst running Rivatuner Hardware Monitor and see if there's anything obvious.
