I have had three power supplies go in the last year on my box. Two were
made by Antec with the same fault of the +5V rail dropping close/below
the limit. This seems to be a known fault and can be fixed. Even a
brand new one out of the box had only 4.8 volts on the 5 volt rail.
It took out one DVD burner and caused strange lockups and hardware issues.
I found that sensors doesn't report the voltages accurately in
comparison to using a digital meter.
Just something worth checking.
