I have an iMac G4 and it keeps crashing. I've zapped PRAM, bought more RAM, re-formated HDD, installed Mac OS X over and over, I don't know what else to do. Even if I boot it up and let it run, it will eventually crash, but at random times. If I re-boot right after it crashes, it crashes again, but if I wait, it doesn't. Any ideas? If you need anymore info please ask.
