Ever since I installed a wireless keyboard & mouse, the sound on my computer has gone screwy. I do use my computer to record. However, when trying to record yesterday, I noticed that I couldn't even hear myself. (Yes, the microphone was on) I could crank up my voice and still no sound what so ever. I had toggled with the sound options and still nothing helped. Is there anyway possible of fixing the sound on my computer? It is only when recording that it acts up. When playing music, videos or what not the sound works perfectly fine.

Move the base unit further away from the speakers and tower.
