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.
