Spoke too soon. After 30 minutes of use, the repaired G5 2.3 (logic board bad, 2nd logic board bad and original processor replaced) again froze and demonstrated the same problems. Freezing every 10 - 20 minutes. New files vanishing. Plus it now won't hold the date and time. Plus when the system freezes, the fans keep accelerating (no software to control them) to the point where it sounds like the computer will explode. If your system freezes, you must hold the power button for over ten seconds on the tower, to turn it off. Do not leave the computer before resolving this. Otherwise your fans may accelerate. So two days later, we now have a new replacement G5. We refused the techs offer to transfer software and other files as they're all likely corrupted after 100's of freezes. So after reinstalling all software, calling the internet provider (wouldn't accept new IP), software upgrade and phone calls to Adobe for confirmation codes for updates, the G5 is still working. We are begging the computer gods to spare us this time.
