I had every thing working for about a month (X3 Chip, 250 gig HD in a 1.0 Xbox, wires install). Today I turned on my Xbox and it turned on and off 3 times, and then FRAGs. Opened it up checked points including d0 and it was all fine, continuity and all. Put it back together fired it up and noticed that only one LED was on, the 3.3V LED, and the same 3 boot frag thing happened. Tried to boot with chip off the MS dash worked fine. So the chip is not lighting the 5v LED, what do I check, look at, or adjust to fix this problem. Thanks in advance.
