This sounds A LOT like you have bent pins in your motherboard. Having only one group of slots working is almost always caused by damage to the socket. Very rarely, it can be caused by an actual damaged or defective CPU, but this tends to be rare--most of the time the CPU will crash with errors and BSOD's in that case.
