what actual happened was that i transferred the motherboard to a new case(Compaq ) after fix everything and boot the pc , i get the two beeps and no screen won\t also come on. please what should i do.......

Welcome to D-A-L.

I suggest you start from the beginning and remove (connections), then reconnect all devices. (Power and data cables/connections.) Ensure all hardware is properly recognised in the machines BIOS. Also ensure no loose/free screws are in the case or under the motherboard.

Once this is verified, troubleshooting can continue.
