When the chip is unplugged from the mobo, the xbox will power on/off, eject, & boot just fine. But when it's connected, the xbox will automatically power on when the power cord is plugged in and boots to the ms dash. The power and eject buttons are unresponsive and the x3 switch is red and the blue hd light blinks steadly. Changing to another bank has no effect. Anyone run into this problem before?
