imac shutting down randomly

I have a 2011 IMAC operating on 10.9.5 with 16 G memory that will randomly just shut down on me. Before it does, it will make a skipping noise, freeze and then shut down. I am a photographer and am always on Photoshop or Lightroom. What could this be? The report says..

If you have third party ram installed remove it and reinstall the original ram to test.
