No boot after board was functional.

After following this fix

My board began to work and seemed to be fully functional. A few hours later and its back to not working

Power light comes on
Fan spins
processor works, it at the very least heats up
the 3 LED's below the USB ports work

I have no video out over HDMI, no ethernet status lights, or power to my keyboard. There appears to be no physical damage to any part of the board.

I am using a 5v/4A power supply and have followed as many troubleshooting steps as I could.
