After Hitting Power Button - iMac Turns off and on after 5 seconds
The iMac will turn on and the screen lights up after 5 seconds, it then power cycles off and then you hear the chime as normal screen lights up and powers off again after 5 seconds, keeps doing that repeatedly.
I already have:
- Disconnect hard drive
- Changed power cord
- Made sure fan was working
Any idea what would cause this?
