my G3 iMac DV (one of the old original types) has started giving me a lot of trouble. A few weeks ago I started receiving msgs. that my C drive was damaged. Before I could buy software to repair it, I started receiving the blinking question mark when I tried to boot up. I was able to resovle that by "zapping the pram" , but now my cursor freezes up upon boot up. I tried starting up with the restore disk inserted and holding down the 'C' key but the mac is not recognizing the disk (It's not booting up from the CD that is). Also, upon start up I get this weird knocking sound that's hard to describe other than it does not sound good :-(
Is there anything else I can try before taking to the repair shop?
