I tried disconnecting peripherals and
resetting the PRAM, that's actually what the computer sounds like it's
doing with the chime repeating ad nauseum.
Another idea: pull out the PRam battery for some hours.

Once upon a time there was a button somewhere inside Macs, that did some kind of "internal setup reset" (maybe resetting the Power Management Unit?).
I don't know if the Mac Pro still has that button.



My Mac Pro has a reset switch on the mobo just to the RAM.
