ok i bough a xbox with no dvd or HD for pretty cheap the lady said it was fragging so they took the stuff out to sell. i figured no prob ill install a chip and it will be ok. so i soldered a chip in and it went really smoothly d0 point and everything. blah and it still frags on me and both blue lights are on. even w/o a HD in it shouldnt frag right? i triple checked my solder points and they all look fine to me. any advice on anything else i could check?
