Anyone having problems with a GTX260 and the 177.35 drivers on Vista?

I have a GTX260 that causes computation errors and regularly crashes the box with a Blue Screen of Death. I've tried System updates, .Net Framework updates, reduce the GPU clocks, re-seat the card, change the PSU.....nothing seems to want to fix it. The box runs fine on a 8600GT.

I read earlier posts about problems on Linux with this card and I could not get it stable on Ubuntu64 either. It seems maybe the same on Vista too?

After reading some posts over at Folding, I see several people with similar BSOD. They fixed it by going to Beta drivers 177.41 or beyond.

So, I've downloaded and installed 177.79 drivers. The machine is running two normal CPU QMC units for over an hour now with no crashes, so maybe it will be ok for GPU. However, I'm over my daily GPU allocation on the box, so I can't try until later.

Box spec's:
3GHz P4 HT, standard clocks
32Bit Vista
GTX260 standard clocks
Boinc 6.3.8
Nvidia 177.35 (now 177.79)

I was rather hoping someone else had some success that I could learn from!

I tried the Beta driver but it was just the same, crashes, blue screen of death and WU errors. Also tried it on Linux on a E4300 dual core machine and had the same. I think a few others have tried the GTX260 with not much success....maybe the GTX series is just too new and the drivers not capable of running this project well?

For now I'm running on Linux with 8800GT's.

Is the card stable in 3D Mark?
