    My 2009 iMac turned off by itself. May have been due to a power outage. It will not turn back on. When i hit the power button, I hear the mac chime sound and the apple logo shows up on the screen. After about 1-2 minutes it shuts down. I have tried to start in safe mode and the same scenario happens.
    Any thoughts?
    Thanks in advance for your help/advise.

    I had This happen to me on my 2008 Mac Pro. What I discovered it was my Display Port cable. So when I unplugged the cable it started normally again! So if you have any Display or Thunderbolt cable plugged in try disconnecting them and try to boot up!

    It's a fairly common issue that a failed/failing hard drive can cause a shutdown during boot.

    Can you boot to your hardware test?
    Boot, while holding the D key.
    If you can get to the hardware test, run both the standard, and extended tests.

    You could try this (no promises):

    1. Unplug the Mac
    2. If the Mac has removable RAM, remove it for 15 minutes
    3. Put the RAM back in, plug in the Mac, try again.
