     One or more IC's on the motherboard may have developed a bad connection
to a pin. With power Off, try scootching up and resocketing the
microprocessor, the ROMs, and other chips in sockets. Actually, you might as
well do all socketed chips and unplug-replug any cables.

     Use alcohol swabs to clean the contacts on all Slot cards and the
contacts on the power supply cable.
