I got an older computer gave to me. I was going to fix it up for my aunt. It had a problem with it's harddrive, would boot up and say non-system disk or something along that line. I got a hold of another harddrive, but now the computer isn't booting. I took it apart and reconnected all cables and moved the ram from slot 1 to slot 2. It turned on, but didn't show any video. I turned it off and it wouldn't turn on again, any ideas?
