Just built a machine with the psu and mobi described in the title. In addition:

Sapphire Radeon 6850
Corsair Vengeance 8gb 1600
AMD Thuban 1055T
500GB barracuda
1.5 TV barracuda

Initial post was fine except the psu was clicking. Computer made it to loading windows screen when blue screen flashes (too quickly to read) and rebooted. After this, both of my hard drives seem to have failed and I get an "invalid boot disc" message each time I start up. Clicking noise from psu stopped only during ONE attempt at booting. I've stripped the computer down to just the psu and mobo and the clicking still occurs.

Is this most likely a defective mobo? If so, is it possible that it could've killed my HDs also?
