I have a 360 s console and my cousin has been playin skyrim since it came out. For the last couple of weeks it runs very slow. After you press start at the begining it take about 15 minutes to get to the next screen and then when he finily get to the game play it frezes up. Now the same disc works fine in my xbox which is an older xbox and it also works on my other cousins xobx which is a console s. I have cleaned out the storage of his xbox but no change. and also every other game we own works fine. Could any one help me.
