Hey all, Need some help with something. I've had my 2.16GHz 20" iMac for 15 months now and it has been fine. In all this time, I've had one kernel panic about a month after I got. 6 months in, I upgraded the RAM to 2GB with 2 * 1GB from Crucial. About 2 weeks ago, I upgraded to Leopard and all was well until yesterday. I had a kernel panic, got the pretty Mac screen saying "you need to hold down the power button". Then when booting into bootcamp + XP I had two BSOD, looked to be in the USB driver for the second BSOD. Today, I have had about 5 kernel panics doing nothing in particular (web browsing, idling, etc). Using system profiler, the SMART status of the HD looks good. No apparent indication of problems in the console. In XP, there are no indications of fundamental problems. Any ideas how I can trouble shoot this further? Diagnostic tools would be good, or just an idea of where to start. No, I didn't get extended support with Apple - wish I had now! Thanks!
