Since it was set for a Mach V board I would assume you are right, the board has been swapped. But that shouldn't make a difference in the PTPro as long as the switches are set at 50MHz bus and no more CPU speed than the card is rated at. I would try backing the CPU speed down to 400MHz and see what happens. Other than trying different settings which you have already done I don't know what else to tell you.
