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 .

Did you take the HD out and replaced it with a SSD? Or did you add the SSD (dual drive setup)?

Try disconnecting the SSD cables to see if the system will start then. If you still have the HD in you should boot up, if you took the HD out you should see a blinking question mark in a folder icon.

When I press the power button, hear some noise - CD-ROM, look like try to start but cant


Recheck your connections between the system and display. Did you damage or forget a connection?
