seems like lack of ram...
download the latest sound driver?
Whenever i move my wireless mouse during any type of sound playback whether it be from Itunes or just a default windows sound, the sound becomes garbled and the mouse stutters around the screen as if all my ram and cpu resources are being used up. i upgraded to the microsoft wireless laser mouse 6000 thinking maybe the 2.4ghz mouse was causing the interference. i still have the same problem with the new mouse. is this a sign i should wipe my computer and start over?
