I have a DR55wg board. If I remove the cmos battery for a minute and reinstall thr computer will start. If I turn it off with the switch It will not restart untill I remove the cmos battery wait one minute and reinstall. The computer starts when I plug the power on from thr back of the case. this is a brand new board.
I am starting it with everything unlooked except for the video card and monitor
Tried everything in thr trouble shooting guide to no avail. Checked the power supply in another computer and it worked fine. Got a new power supply anyway and the problem went away.
