I have a DQ45CB board that, when I plug the power cord into the power supply the computer turns on, stays on for about 30 sec and then powers off and won't turn on again at all. All of the components are verified good and compatible. Tried a known good power supply and it does the same thing. Same power supply in different computer, and it doesn't power the computer on as stated before, so I know it's isolated to this board. Board does not throw any beep codes during the initial plug in power up, but the AMT lite blinks.
