Unstable OC'd GPU=BSOD?

Is this possible? The GPU has never gone into 2d mode or EU'd any work units. Has this happened to anyone before? I have just recently added an MSI Twin Frozer GTX 460 @ 900/1800 (w/ a slight voltage bump) in an I7 930 @ 4.0Ghz -bigadv (strictly folding) rig. The GPU never gets over 60C. The rig has rebooted a couple of times lately due to BSOD. It is running Vista64. PSU is a Seasonic X650 Gold. The rig has one HD, and 4 120mm fans running on full.

I'm wondering if my PSU is adequate, or if -smp 7 vs -smp 8 has anything to do with the BSODs (tried both, -smp 8 was slightly better), or if my GPU is unstable. I'm just trying to narrow things down before I work on getting the combination stable. Sucks to come home from work to a -bigadv rig that's been sittle idle for 9 hours or more. I can't imagine the wu's and points that would cost on an SR-2 rig. :mad:
 
What BSOD's? The stop error code (bottom left) and error (top right) do actually provide helpful info. It could be a flaky PSU (although that should have enough juice for your system), it could be the mobo it's hard to say without the error codes.

When I've pushed my 460 too much, it rarely BSOD's. It just down-clocks and displays a notification saying the display drivers crashed.
 
The only thing I can remember from the info was something about a integer. Like "unexpected integer" or something. I'll take a look after work.
 
Then that eliminates the GPU since they are solely for floating-point operations. My hunch is more volts on the CPU.

Awesome! I would have never figured that out. I never had this problem until I added the GTX460. I bumped the voltage on the GTX460 from 1025mV to 1037mV, and it's still running 900/1800 and staying under 60C! I'll bump up the CPU voltage a notch when I get home. Thanks!!!
