I'm on a mac at work currently, and it freezes up for about 5 seconds all day long. It's always in the same pattern. Freezes for 5 seconds, fine for 5 seconds freezes for 5 seconds. It's fine for about 15 minutes then then it freezes again. I can still move my mouse and i my music doesnt pause, but everything is un-responive. Any suggestions? It's really annoying.
