I don't have enough trials to rule out coincidence, but it seems to happen to me only when I have a web cam connected. I can't figure out what the connection is, but I was experiencing the problem with one camera, disconnected the camera and returned it because of unrelated issues, and didn't experience the issue again until I had connected a (different) camera.
