I'd want to know the true voltages before I did anything drastic. Cat. Q1467 costs just $12 and even has a data hold function.

Thanks Billy

I back probed the power connectors and the voltages are ok

Molex connector to video card
+5v = 5.16
+12v = 12.0
GND = 0.0002v

Main ATX Power
+3.3v = all 3.42v
+5v = all 5.16
-5v = -5.11v
+12v = +12.02
-12v = -11.77v
GND = -0.0035v to -0.004.7v

The original problem has not occured again so hopefully it was just an isolated incident. :)
