Does anyone have any suggestions? I guess my next move is to pull the mobo from the case, remove the battery for a day, then hope it posts so I can do a BIOS recovery flash.
Update: It turned out my problem was the cpu. I had bought a different mobo & still had problems, sent the Intel mobo & cpu into a lab & they verified that the mobo was ok, but the cpu was "unresponsive". The technician speculated that it was caused from ESD, but I don't see how that's possible, because the cpu was under a cooler sink when it failed. The lesson I learned was not to use my PSU to shut off the machine unless there's no other option.
