I had the matrix chip working in my system for a while, it came loose, it was striped. OK, Fine, i bolted it on. Now it will not work. THere is grounding and i have a v1 xbox. THe xbox boots three times with and with out the chip aligned and the dips switched. I have tried 2 different matrix chips. What went wrong?

I am using a verified bios that has worked before, xecutor
