I had a similar issue with a unit a while back. Chances are it's not the main board but a component that plugs into it. Try disconnecting as many non essential items such as wifi card, speakers, trackpad, keyboard etc. and power the unit up.
I had one unit that was water damaged and the trackpad was causing a short, disconnect it and it boots ok.
Another unit I never narrowed it down but obviously a component that connects to the main board was the issue. When you use the reset switch you are resetting the circuit so it clears the fault (temporarily). Remember that a circuit doesn't end in the MB, so any defective device that is connected can cause an error condition.
