Fiery,
I did not notice before, but AIDA64 is showing the +5v reading as 6.1 Volts!
Something is definitely off.
EDIT: Never mind, it appears to have gone back to 4.8, which is actually a bit low, but better than the 6.1.
SECOND EDIT: OK, this is strange, after overclocking, it seems the +5V does display as 6.1V.
