A few months back I picked up one of the iMacs with the swivel neck from a college surplus sale. It worked fine for a while, but one day i went to boot it up and it just hung on the while apple. If memory serves it either had Tiger on it when I got it or I loaded Tiger on it at some point. I've tried reloading the OS but I can't get it to boot from any install DVDs I have. Thinking it was the the DVD that was the problem I burned several new copies from the image I have using both DVD+R and -R just to be sure. Made no difference. Anyone else have this trouble before?
