My good old computer just broke, and I'd like to fix it. What happened was a metal backed and operating phone was dropped onto the motherboard(don't ask). I ordered a new, identical board, so I'm just wondering, a)How careful do I have to be with the new board? What parts are okay to touch or not? b)Once it's in, can I just start it up? Or is there something special I have to do? and c)Will I lose anything?
