I have a 2011 mid year 21.5 iMac intel i5

the computer doesn’t power on. Went through all the reset solutions yada yada nothing worked.
Has 1 green led never 2.
Replaced power supply
Nothing.

went through unplugging and resetting and nothing happened.

left it sitting and 10 min later I heard the hard drive and optical drive start spinning. Then cut off.
Then I it powered on again and got a chime.
Turned off
Started up again and got to loading screen.
Then powered off and on about 6 times and then turned off completely.


Couldn’t get it to power on again. So I unplugged and reset again. Nothing
About 5 min later it started by itself again and would do everything it did previously.

Went through entire process maybe 20 times over a 2 day period. Once it got to the log in screen then promptly shut off.

Any suggestions would be appreciated

Figure it’s hardware related, have replaced power supply already, just hate throwing parts at it without knowing what it could be

thanks in advance
