To add to what you've already been told..... Modern boards such as the logic boards which are used in Macs and other computers have the components surface mounted. In some cases, the board has multi-layer circuitry in order to save space. Only certified Apple Technicians at official repair depots have the proper equipment and software to test these boards. And since everything is proprietary, that information is not released to the general public. As Nick pointed out, its usually best to just buy a new machine rather than try to salvage that one. Not saying it's impossible, but very likely not practical.
