Sigh, help please.

For the past month, my rig has been giving me tons of problems. I usually leave my computer on at all times, so one morning when I wake up and see it is off, I was a little surprised. I tried to turn it back on, but it wasn't getting any power at all, so I unhooked everything and just let it sit for a while. After an hour or so I hook everything back up and try again, and it actually turns on this time. It boots fine, loads Windows like normal, then just instantly crashes as soon as it finishes. So, I decide it's a problem with my OC and reset everything to default, and it seemed to fix the problem. Things were fine for about 2 weeks, but one night it decided to crash while I was gaming. I reboot it, and it doesn't post. I turn it off completely, unplug the power and let it sit for a few minutes before trying to turn it on again. Surprisingly it turned on and worked fine for another day or so. After that, it would take 20 minutes just to get the thing to post. I talked to my friend about the problem and we decided it was the PSU. Apparently Rosewill psu's are a no no.

Anyway, I decide to order the Corsair 620HX to replace it, and after putting it in, it seemed to solve the problem. No boot troubles, and I could OC again, so I was happy. One week later and I start crashing in games, and getting random errors I've never even seen before in Windows. I decide to do some stability testing with Orthos, but that didn't last very long. With all stock settings, Orthos would fail after one minute. With my overclocked settings, it would only last 40 seconds. I'm kind of baffled as to what the problem would be, I've tried upping voltages and what not, but it doesn't seem to do anything. This is the error I get.

FATAL ERROR: Rounding was 0.4999012947, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 2 seconds - 1 errors, 0 warnings.

My specs are :
c2d e6400
Corsair XMS2 DDR2 675
Asus P5B
eVGA 7800GT
Corsair 620HX PSU

Any help or advice would be greatly appreciated.

Check the Windows logs (Control Panel -> Admin Tools -> Event Logs) and see if there's a theme in the error codes that's occuring, it could be that you've damaged one or more parts of the computer by using a bad PSU.
