So, on my original Xbox i've been playing a lot of Halo 2 dead or alive 2 and burnout 3 lately and nothing else but about an hour ago i put in Deus EX: invisable war in. When it got to the main menu to load the game i pressed start and nothing happend and the controller was not responding. I then restarted the system and the same thing the controller didnt move, then i tried another controller. same thing. i also tried shutting the system off and unplugging the power. i waited about 10 minutes and nothing. So i gave up and put in Counter Strike. SAME THING AGAIN the buttons dont respond in the main menu, i then put in Halo 2 and it worked perfect, then i tried Deus EX again and the controller still didnt respond.
