I just built my wife a new computer but it wont boot up. I get the error code 55 on the LCD on the motherboard if any RAM is plugged into the the A1 or A2 slot on the mother board and the 04(D4) error if I have RAM plugged into the B1 and/or B2 slot. I have taking the CPU out and back in and remounting the heat sink. I even went so far as to unplug everything from the MOB and remove it from the case and then reinstalling everything to no avail.
