My wife's 20" G5 flat panel iMac, which is just 5 months out of 3 yr Applecare, is having major problems. First it started freezing up frequently and all we could do was a hard shut down. Now after booting up within just a few minutes of simple surfing we get the black box in the center of screen with white text which I think is a kernel panic. Says it must be shut down by holding power button the rear. I reloaded the system software and got back to 10.4.2 but when I tried to update to 10.4.11 with the combo update, I get the kernel panic. Does this sound like it might be power supply or logic board?
When I did google searches I was appalled at the number of complaints on these flat panel iMacs for power supply and logic board problems... both for the G5 and the intel. I saw a replacement video on the web showing a power supply swap and I think I could do that but would be hesitant to try the logic board. Are my symptoms suggestive of a defective power supply?
