Logic board or power supply malfunction
I tried to put ssd drive in my imac mid-2011 , and then I tried to turn it on , I heard the sound of the drive and nothing else happens , it just turns off . I turned off the display to get to the logical board. 1 led lights when I press the power button led 2 turns on and shuts off immediately . sometimes led lights 3 lights , I hear the sound , and it breaks not completed . tried to reset smc but failed. tried to include imac when the fans are running at full Power steering . In this mode, imac is behaving strangely , the fans turn on one by one after every reboot .
