I have the same problem with my mid-2011 27" iMac with the phantom restarts. This can be during startup, during the loading bar at the Apple logo, immediately after hitting the login button after typing my password and during use.
I have noticed that it will restart, and then on the second boot it will last a little longer before restarting, and the third boot will last even longer....and sometimes 20+ restarts later it will stay on perfectly fine.
If I put the iMac to sleep, the phantom restarts return (usually restarting straight away again). Same applies if I shutdown, let the HD go to sleep, allow the computer to load the screensaver etc.
I have gone into power saving options and disallowed the iMac from going to sleep ever. This worked for a short while. and the iMac lasted longer without restart, but the phantom restarts returned after a week.
So far I have tried:
* Replacing the RAM cards (twice with two different brands; Corsair & Kingston).
* Replacing the HD to an SSD.
* Replacing the fan near the CD Drive.
* Replaced the screen.
* Replaced the Wifi card.
* Replaced the Graphics card from another mid-2011 iMac entirely.
* Changed power cords.
* Changed power outlet.
* Changed the processor.
* Changed physical address and plugged the iMac in at a relatives.
* Changed country! (Yes, I was living in Thailand and now living back in the UK)
* Unplugged all additional peripherals such as USB etc.
* Installed various fan apps.
* Formatted the SSD and reinstalled MacOS.
* Formatted the HD and reinstalled MacOS.
* Downloaded MacOS to a USB stick and installed from that.
* Installed various versions of MacOS; Lion, High Sierra.
+* Tried Disk Utility on startup to repair/recover.
Apple have been no help what so ever as the iMac parts are no longer supported or maintained by Apple, and the default OS is no-longer supported. So they will not entertain me in the slightest.
The only thing I have not yet tried is throwing the iMac off a cliff.[br]
[br]
I read on this thread someone solved there’s by removing the Wifi card… so that’s my next attempt. Anyone else have any recommendations for me?
