Default Overclock no longer stable bad power supply ?

Hi,

My overclock is no longer stable on my phenom II 940 @ 3.6ghz. I noticed game crashes and set it to default settings and no more crashes. Prime crashes after 30 min or so when overclocked. Could this be a faulty power supply ? I noticed 1/5 times when my pc starts my video card fans make a heavy sound just before windows logo. It's not the same spinning sound they do during post. I have tried all combination with voltages with no results. Freezing only happens when I game so im thinking power supply can't provide load. OCCT stress tests after 1 hour does not freeze pc. Memtest after 12 hours ok.
thanks.

Most likely the nvidia drivers.

What version are you running?

I am using 195.62 and the only crashes were in batman AA

It's unlikely that the PSU is causing this.

Thanks for replies. After more testing it is indeed the nvidia drivers. Nvidia is pissing me off lately. They promised faster cards then ATI and the new 480gtx is just barely ok. I am a huge NVidia fan and will be switching to ATI this summer.

Thanks Guys
