I have found on two powerdown problems very similar to yours that the 
fix was to improve the isolation of the MB from the case. You can prove 
that by running your entire system out of the case (can be tricky to 
have the power cables reach the MB). Powering off may work then. Anyway, 
I used the red washers to insulate each screw on both sides of the MB. 
It worked - on two different MBs.
