I am writing this on my laptop which contains a brand spanking new motherboard. The installation went ok. I think there is something loose as once in a while....the damn thing just shuts off. Could just be the chips on the motherboard seating themselves. The board was a factory new board. I'm happy. I can't imagine what "normal" people do when laptops die.....I guess spend boatloads of money. It's good to be me.
