I just now tried to start my xbox with the chip enabled and I got two reboots and then the error lights but nothing appeared on screen. I made sure everything was plugged in to see if that would change me not seeing an error number but it didnt work. I booted to the original m$ dash and the clock had been reset, so i figured that was the problem... so I set the clock and then tried to boot with the chip enabled and It didnt work and the time got reset. What is the problem? I dont understand why it decided to do this after it has been working for months.

your switch have not been moved
what chip have you got???
what bios???
