Have you been monitoring temperatures at all? I would also guess that it's your PSU, though. Simply because Rocket Fish is not a good brand.

In fact, the PSU is manufactured by Huntkey, which doesn't make a 700 Watt unit but Rocketfish has re-labeled the original unit as such.

Seems like even being a 500 Watt unit, it would still be able to power your setup, though.

I would download a program like Coretemp, Speedfan, CPUID HWMonitor, etc. and see what your temps are at idle and while gaming. If they got very high, then you might be overheating your computer.

You could also run a program like Prime 95 while your temperature monitor is running and see what your load temps are like.

To check for PSU issues, download Everest and run its stability test program and watch the voltages during the test.

I stopped using a 12v molex to 8 pin conversion cable, and started using the 8 pin cable my power supply came with. I noticed the voltages decrease but my 12v 8pin cpu cable is just barely long enough for my computer it's too close the my Hyper 212 cooler.

So far no crashes and I did a fresh Windows 7 install on my OCZ Solid 2 State series 60gb hard drive.

I got AIDA 64 Extreme Edition

Have you tried playing a game yet to see if it still crashes?

It still crashes, Fallout 3 and office run fine without crashes. AIDA 64 says Zotac Nvidia GeForce GTX 460 768mb running at 40% speed how do I fix that?

I fixed it by unlugging the SLI molex port. Quite dumb
