Hi Rockhouse Bad Boy,
Does your motherboard have a small piezo speaker on it somewhere? Or does it require hooking up a small case speaker (not the stereo speakers that connect to the sound card)? You need one or the other in order to hear the POST beeps.
Try starting up the motherboard without the RAM (with the video card installed). You should hear a BIOS beep code telling you there is something wrong with the RAM or it's not present.
If you don't get a response, try it without the CPU installed (some motherboards will let out a steady wailing tone if the CPU is installed incorrectly or not present).
If you still don't get a response, inspect the motherboard and CPU carefully for any signs of damage. One or the other is either damaged or defective.
