I've got a 2003 iMac G4, with a 1GHz processor. It works, mostly. It'll boot when it feels like it, and loads up 10.3 Panther (my OS of choice). However, it will inevitably crash. I've tried replacing the RAM, because I had a similar issue with an XP machine I own, but it did not help the G4. Now, I'm fairly certain it's a processor issue. I've reinstalled Panther, which was tedious process of rebooting over and over, and still no luck. I can find a replacement processor on eBay, for a reasonable price, but replacement 1GHz motherboards are darn near impossible to find (especially for a broke college kid). If any of you know of a service or a friend who can help me, please let me know. Thanks!
