I put a matrix into my xbox and it was working fine. My buddy came over one day and was looking at it because it would just shut off sometimes. I would move the power cord and then it would start back up. So I was think bad cord or connection. So he moved the chip and then I had to readjust it because he got it out of alignment. Now when I turn it on it freezes at the MS start up, or when I enter a game. Any help would be greatly appreciated.
