My Xbox 360 recognizes there is a game disc in the tray, but when I tell it to "Play Game", the screen turns black and disconnects from Xbox Live. A second or so passes and it reloads the dashboard and signs my profile back in. I have seen the other forum posts instructing users to delete their profile, clear the system cache three times, restart the unit, and redownload my profile. I've now tried these steps three times, and unfortunately the second involved me deleting my profile and items (Ouch), but to no avail. Is there anything else I can try before giving up on it completely?
Oh, and it still reads DVD's and CD's just fine, games are the only things that cause this problem.
