Hello friends, I received this g5 in working order, plugged it in a day later and screwed it up! What actions should I take to get this computer working again. Currently when I turn on the computer there is a grey screen with a small folder on it. When I try the 2 discs that, what I am told, came with the computer, negative messages occur. Install disc- Starts off looking like a nice install and then "bundled software cannot be installed. Apple hardware test disc- instantly pops up with "Apple Hardware Test does not support this machine" My question is, What steps can I do to make this an operational computer at minimal cost. I would love to give this to my father as a nice surprise.
