Guitar hero 3 retail crashes xbox 360

[Bushwick2002]

hmm its something with my xbox 360; i tried the game on my friends 360 and it work fine. tried my friends guitar hero 3 retail game on my 360 and it boots up to a black screen. Also made a backup copy of my friends guitar hero 3 and same black screen(Thought it could be protection like Gears of war retail, where it dont work on old hack firmware). guitar hero 2 retail seems to work fine. Since theres no HDD/MU connected, could it be my dashboard is corrupted?
