I know the Corsair 520W should have enough power, what i meant was it may not be producing the power the system needs for the RAM,GFX, CPU and mobo due to a PSU fault, ie: Low voltage on the 12v rails, which can cause HDD corruption.He has a corsair 520w psu, which is more than adaquate for his setup btw.
I also thought he was going to try a different HDD, infact, i thought he already had tried a different HDDI thought u said u did have a old hard drive, a ide one you were gona try.
