I have an Executer 2.2 chip and it "was" working fine then, I woke up the other day and no video is appearing on the screen, and my hd doesn't seem like it's fully booting. But when i first turn it on the only thing i can hear is the xbox loading sound. Is my xbox broken for good? or is this problem fixable? As for now my progress in ninja gaiden will be haulted!
