My x-box completly cut out on me the other day, no audio or video, the power button was flashing orange and green. I switched Av packs from a high def pack to the regular stock one , the light returned to green and it booted up but then it turned to flashing red and green and gave me a error message saying i need to service my box, it had a number 7 in the upper left hand corner of the screen. Anyone know whats going on here??? thanks

nm problem fixed, just forgot to plug ide cable to mb. that was stupid
