When i go to play NFS Most Wanted on my dashboard, i click "play NFS: Most Wanted" but when i click it, it goes to a black screen for about 10 seconds and straight back to the dashboard. I have restarted it several times and unplugged it. All of the sounds are normal for 10 seconds then my xbox goes quiet and goes to dashboard. This has been going on for several days but I am just now getting to post this. This happens to ALL of my games. Anyone know how to fix this?
