Hey, I just bought an iMac G5 off ebay and today I tried to use the Tiger install dvd because the previous owner had deleted software like textedit, etc. Anyway, I put the disc in and clicked on Install Mac OS X, then clicking restart. Now here's the problem, once the iMac shuts down and begins to restart, as it is on the grey screen you can hear the disc being read, then as the background goes a different shade of grey and the Apple logo appears, a minute or so passes and then the iMac begins making a lot of noise. I went away for 10 minutes, came back and it was still doing the same thing. So I'm basically looking for help because I really want to erase and reinstall everything, so help. tips, experience in this would be very much appreciated. Thanks.
