I got a brand new v1.6b motherboard, and matching hard drive, and matching power supply. Installed it in my v1.0 case, everything matches up except the v1.0 box had an extra mounting screw, which i didn't think to be an issue. anyways, I soldered the pinheader and the lpc rebuild fine, booted up the chip, flashed it from cromwell 3.03....viola! now it booted up great, left the box on for an hour, called the guy to tell him his xbox was done....great. I put the case back on, plugged it back in, ready to install new dash.....and now nothing happens. I push power and eject, nothing. not even the slightest sign of power. I have a meter and while plugged in, the power supply reads several different voltage levels and there is voltage going to the motherboard... the only thing that doesn't make sense is that it was working fine, and now it's not. no smoke or discoloration on the supply or board either. any ideas? i'm about ready to trash it.
