I have an old Power Mac G5 I got for free that I am trying to fix up. When I had first started it months ago it had worked beautifully. Then I had moved and brought it with me and all of the sudden it does not turn on. As in the light flashes for a split second when I plug it in but all that means is that it's getting power. I had Unplugged every cable and plugged it back in as well as hit the Logic Board Reset button. I had also placed the ram in order according to the Power Mac G5 website says and to no avail. I had even repeated the old battery. Can someone please help me, no one has ever had this issue, I've scouted dozens of forums, nothing
