Ok well I recently upgraded to Windows 7 like a month ago and I had no problems, until like 2 weeks ago. It happens on occasions, ill put on a song and it will stutter and lag my computer, or my msn sound will go off and it will freeze for a second. I downloaded the latest drivers and still it freezes, I checked if I have too much stuff running and it is not that. I don't know if anyone has a solution for that. I have a Gateway NV44.
