Alright, just thought I would check. FWIW I have an asus 7900GS and I have literally never once had Sins crash on me. The only weird thing I get is an occasional split-second white screen effect late in a game when things get very heavy. I'm using 169.21 on XP. I know IC mentioned that this seems to be an internal Nvidia bug and that people should wait for the next release, but, whatever is causing it is obviously not happening for my hardware/driver/os combination. Just as a thought, have you trieda) updating the motherboard's drivers (either from the manufacturer or using generic chipset drivers)?b) using Rivatuner, Ntune or similar to create an 'always 100%' fan profile to eliminate the possibility that the card is overheating and crashing the game? Nvidia's stock fan profiles are biased so heavily towards 'quiet' that a sustained heavy load will often cook them even without overclocking.

It seems to be mostly a Vista happening, and I use Vista HP 64.
My motherboard's drivers are the latest.
And as far as RivaTuner, well, my Video Card does not have a fan. It has an Accelero S1 and is passively cooled.

I'm trying out the beta drivers because Nvidia appears to be rather slow moving to address the problem publicly. The latest drivers, 169.44, address a single issue in Crysis... but nothing else. Before that, 169.28, it happened, and 169.25, the crashes still happen. I've tried several others, but they all crash eventually, at random.
