I got a premodded xbox about 2 months ago from someone and its been working great untill a few days ago the xbox will not turn on. What happens is i press the power button and the xbox turns on, turns off, turns on, turns off, turns on, and then flashes Red and Green. After seeing this i decided to disable the chip and see if it worked that way... nothing. Im hoping someone knows whats going on and hopefully you can help me with this little problem.
