@DouglasLane,
Did you unplug the power cord every time you were inside the chassis. ? Were you properly grounded to the chassis ? Unplug the power cord from the unit. Either keep grounded to chassis by hand or grounding strap. Return it to its original configuration (RAM). Replace cable, and restart. It is will not start it is probable that you damaged either the RAM, or static shock to the motherboard.
