As stated in the title, my OS keeps freezing when I leave it idle (approx. 20 minutes). I checked the event log and it said that AMPingService failed to start in a timely fashion. I went to msconfig to turn it off, but it still freezes. I end up having to do a hard shut down. Any help would be great as this is my second reformatting of this system due to issues I've been having and I would really like to not have to reformat a third time.
