Check all connections to the motherboard that they are correct and fully seated. Pay special attention to drive connections and memory DIMM's. Check that memory is seated fully in the DIMM sockets.

The memory DIMM's should be installed in the 2nd and 4th sockets going away from the CPU.

Reset CMOS. Shut down and disconnect power cable, remove battery and short the pins for 30 sec's to a minute. Reassemble.
