Ok heres a good one for yas..
2 weeks ago, my system went nuts.... It crashed and rebooted 3 times... noraml problem... then it started up and kept rebooting by its self randomly and repeatedly... when it started to repoot it would do it as little as 3 times in a row and as much as 100 times...
So I left it off for a few hours, came back from work, plugged it in, it didnt reboot, so i left it on playing a dvd over night for 12 hours, after that it worked 100%,, well 2 weeks later (now) It did the same thing lastnight.. the video went nuts, and it rebooted a few times, now I get the power on , reboot, reboot, reboot, red blinking light.... and thats all no sound no video... reflashed the bios with 12 different bioses .. no luck there...
Its a Matrix chip in a V1.0 M/B, I am going to try the D0 direct solder to the top of the matrix, but that wont help, cus with out the chip the xbox does the same thing.... now thats fucked... same problem, lasts for 2 days goes away for 2 or 3 weeks then comes back... i was playing 4 hours before it started doing that lastnight...
