It happens only on the desktop. The beeps are long occurring beep and I don't think it is the GPU it is seated in properly and windows reads the GPU just fine and graphical games work as well. It isn't a CPU overheating problem, because that would be a continuous High then Low beep, which this is not. When I shut my PC down I will try taking off the GPU and re-inserting it. But I plan to get a new mobo soon anyways.
