Sorry for the double post, but I can't seem to edit my first post for some reason.
I just found something really interesting.
My mom and dad both have computers as well, so I decided out of curiosity to run LatencyMon on their computers to see if they might have the same problem. LatencyMon said both of their computers also have real time audio/video problems.
Attached is the screenshots of their LatencyMon results.
