i recently install a duox2 white on 1.6a mobo, it was working ok for about an hour then the xbox went off, then on for 1 min. then off again, when i push the power and eject button nothing happened, after i unpluged the power cable i heard a "fade out" scratch on the tv speaker, if i plug the power back the it turns on by it self for a litle while then the same issue repeats. I wait about an hour to try again and i was able to use the power and eject buttons again, but after 30 mins, the xbox repeat the symptom.
Please help me
