Hey! My friend's iMac G5 broke. They gave it to me to look at. The serial number was in the range of a defect apple has recognized (can be seen at http://tinyurl.com/c8pjk7) and had a loud fan and was getting scrambled video/very erratic behavior so, I gave it back to them so they could take it to the apple repair centre. After getting a quote they decided it was too expensive and offered the broken mac to me. Now when I try to boot it, I get the chime, but the screen does not turn on and the fan is LOUD. The system then goes into standby mode and, if I try to bring it out of standby it just crashes. I can however target disc mode and see the hard disc. Any help would be really appreciated! Thanks!
