If your OS was previously working fine and "suddenly" this problem appeared, there is probably a solution. As a Unix-based OS, there are lot's of things built in to repair and restore the OS. However, this type of problem could signal hardware failure. There are several threads in the Archives of this list that discussed similar problems. Have you installed or modified anything around the time the crashing began? I would run the hardware test disk that came with your TI, then run Repair Permissions from the Disk Utility. If the problem persists, then reboot into single user mode (hold down command & S keys on boot up. At prompt type in "fsck -y". This may take a while; repeat that command until the final output is: disk appears to be ok. Then type in reboot and let your system restart. Also resetting the power manager may do the trick, their are instructions for that in Sherlock -> AppleCare. While this may sound complicated, all of those steps can be done in considerably less time that a back up and reinstall of the OS (and some of them will have to be done after the install anyway). -- <><><><><><><><><><><><><><><><> Mike Bigley Maineville, Ohio http://www.norbertrunning.com Please support an American Indian Elder & Medicine Man by visiting the above link. <><><><><><><><><><><><><><><><>
