I'm new here, and relatively new to Apples, so please forgive my ignorance.
I've got a dual 1.8 ghz G5 with 1GB RAM (installed by Apple at purchase).
I updated (clean install) from 10.3.9 to 10.4 and my G5 began to crash with increasing frequency. I assumed the problem to be a Java conflict, because Azureus is known to cause problems with dual processor G5s. Azureus had, in the past, caused kernel panics, but after manipulation, it had run reliably for the past six months (on 10.3.9). Hoping that the problem could be resolved by an updated Azureus (after 2.3), I decided to re-install 10.3.3 (which came with the G5), updated to 10.3.9, and began operating as usual. The G5 continued to freeze. I tried leaving the G5 running with no additional applications running. It continued to freeze. I made another clean install of 10.3, updated to 10.3.9, and left the computer run. I did not instally any other software outside of directly from Apple. It continued to freeze. By "freeze" I mean to say that sometimes the screen would go to the "Your computer needs to be restarted. Please hold down the power button to restart" screen and sometimes it would just totally freeze. The cursor would not move. Sometimes this would be accompanied by louder-than-usual fan activity, but not always.
Sometimes it will even freeze before it finishes booting.
I ran Disk Utility and checked/repaired permissions.
I ran Tech Warrior, from the Apple Care pack.
I ran the Hardware Check on the original install disk.
I ran memtest 22 times (looping) with the original RAM configuration.
I switched the RAM and looped it for another 24 sessions.
I reset the PRAM 3 times.
I booted in safe mode.
I removed all devices from the G5 - no iPod, speakers or Internet.
I re-set the firmware.
All this and it still freezes.
I've been watching Activity Monitor to try and see any pattern to the freezes, but the CPU and RAM will be running fine and it will still crash.
I even re-installed 10.4 (clean install), and it froze before I could type a complete sentence in TextEdit, with nothing else running.
To me it doesn't look like a software problem because all I'm running is OSX. But it also doesn't look like a hardware problem because the RAM checks out okay and everything else passes Hardware Check and Tech Warrior.
I'm completely stumped.
I would gladly bring the G5 in for warranty servicing, but the G5 was originally purchased in Canada about a year ago. I now live in Korea, and Apple Korea refuses to service the G5 under warranty - which is limited to country of purchase.
One possibility may be a faulty logic board, and for a dual processor, those are none too cheap. I know of no way of discerning if this is the issue.
I'm hoping some of you Mac Gurus can offer some insight into this truly perplexing delimma.
Namaste.
