I recently installed a xenium ice modchip (highly recommended to anyone .. easy as hell) then realized a 120 GB hard drive would be a nice touch, so I threw that in as well. Everything works well except after the xbox is left on for more than 5 minutes if I turn it off it won't come back on. It starts .. stops .. starts .. stops .. then flashes red and green but does not bootup. Can someone help me please? I'm also not sure I got access to the full 120 gigs. If you can .. tell me what you know. Thanks.
