I got a powermac g4 quicksilver. I don't know much about it, other that someone decided to smash it up pretty good when it wouldn't turn on. I found it by a trash can. I got it home, and started to part it out, and it turned on as I was taking out the motherboard. I had it plugged in from when I was trying to get it to work. So I put it back together, and turned it on. It only turned on by wiggling the upper right corner of the motherboard. nothing else would turn it on. Power button only turns it off. Now wiggling the motherboard does nothing. I tried everything, but it wont turn on. Does anyone know what the problem with it is?
