I would unplug the atx power supply connector and remove the board battery to reset the bios. That should bring the board to life. You'll have to enter the bios using an "f" key displayed at the post screen and change the boot order and check the fan settings "smartfan" in the hardware monitor section, save and exit. If you still have an issue, I would remove the board and inspect underneath for a loose wire or screw. You may have a short somewhere.
