Has anyone else had problems with their mac randomly kernel panicking at different points during start up? I tried doing an archive and install, repairing both permissions and disk structure, and reseting the PRAM. I'd test the hardware, but I can't find the CD for the 800 G4 iMac. I don't believe it's hardware based because one out of five times it will start up and be stable for weeks or months. Any ideas, or know where I can get a hardware check CD?
