Is it possible the machine is not restarting, but it waking up from hibernation mode? How old a machine is this? > Sounds like a hardware (mobo) problem to me. Time to get a new iMac? It's *always* time to get a new mac! But seriously, not necessarily. The usual things to try apply: 0. Is all the software up-to-date and patched? 1. Shut down the computer and unplug it from power for at least 30 sections. 2. Reboot with the shift key down, login with the shift key down. Reboot. Then, if the problem persists, 4a. [create a new user if there isn't a second account] 4b. Restart and login to another user account and see if the problem continues. Still problems? 5. Try to run a speed test on the disk. You can do this manually if you're CLI literate, or there are some free utilities like Blackmagic's Disk Speed Test. If the disk is super slow, it is probably failing. Backup and replace it, or get an external to boot from. 6. Reinstall the OS. This is pretty much a last hail-mark swing-for-the-fences. -- No Sigs.
