Hi, I was downloading warface while playing battlefield 4 when suddenly my screen froze. I thought it was a regular freeze like on the map dawnbreaker, but when I then restarted my console and put in halo 4 it said that my disc is unreadable and i have to clean it. I did it but the same message came back again and then when i get booted to my dashboard my screen freezes. I cleared my system cache and it still keeps on freezing. When i turn my console on it asks me every 2nd time to do a system update. I haven't had any problems with any of my consoles. Just this 1 year-old xbox started to freeze. Can anyone help me that possibly had almost the same problem?
