OK, first it seems that you have NOT read the top sticky on the main forum, because you have given us close to NO information.
We don't know what ver Xbox you have, version chip, (red board or no) WHICH Bios file you are using, (ie the X3 3108, or the X3 3108v16plus) if it was from xbins etc.
I would suggest that you try taking OUT the power/eject adapter.
(It is NOT needed for the chip to work, you just won't be able to disable the mod)
Once you find out if that fixes it, you can move onto a permenant solution.
Help us help you.
