What is wrong with my iMac?
I have a iMac g5 that had a broken logic board and power supply. I replaced the logic board and power supply and now the iMac will start up. But the problem is something is wrong with the operating system. It will just load when turned on and the fans will get fast and then shut down. The hardware is fine. But I tried putting in the install disks and holding command c but while booting the screen will be white for 10 seconds and then continues to load again and do nothing. What do I do to fix it? I heard I might need to replace the hard drive and do a install but I don't know. Does anyone have any ideas what to do to fix it. - thanks
