i worked on a late 2005 g5 DP this week that i couldn't resolve, it went to macauthority today. after 15 minutes or so, it would freeze. leads me to believe some component was overheating. automatic restarting sometimes occurs due to heat issues. i wonder if a specific component is starting to fail in the G5's? i will know monday what the problem was with this particular machine and pass it on.

i don't suspect your target disk hard shutdown to be the culprit, but the update might be a possibility. one other suggestion is to plug it directly into the AC to eliminate the possibility of a failing power strip, voltage swings will cause shutdown or restart. best...jf

I've run into an unusual problem with my G5 running OS 10.5.2. It
began after I transferred some things via firewire from the G5 to my
daughter's new macbook last night and had trouble getting the G5
released by the macbook when we were done. an apple tech guy said to
shut down the G5 and it wouldn't do any harm. I also installed some
software updates last night from apple. Today I've noticed the G5
frequently restarting on its own and it sometimes is after 15 or 20
minutes I think. I am using time machine with a western digital 500
gigabyte external drive. I have run repair preferences and disk repair
and that didn't seem to help. I will enormously appreciate any
suggestions--I'm afraid I did some significant damage to the computer
with the firewire transfer problems. Thanks for suggestions--Ben Zion
