I have had two Antec power supplies fail on me.  In both cases the +5V 
rail was going low.  In one case it took out my DVD burner.

The MB voltage monitor didn't show any problems but my digital volt 
meter did.  On further investigation, I found that many people had the 
same issues with Antec power supplies and even have a fix for the 
problem online.

Take a digital volt meter and measure the voltages at one of the plugs 
while the system is running.  Then load the system.

I was away for the weekend and just saw this.
