Derrick, one other thing now that I am grasping at straws:

This KSU was moved when they moved their office. I set it up at the old place and here also but I didn't move the equipment. When I opened the case they had stored the power cord in the KSU in the compartment under the card slots. Since someone had opened the case I have scoured it carefully and notice the switch on the PMU (at the upper end of the power supply area) is in the off position. Do you know if that is normal?
