Insane CPU spikes in 11.3

Hey guys, i am having some insane cpu spikes in Pro Tool 11.3, i am on a 2011 Macbook Pro 16GB Ram external Buffalo 1TB running the audio. It is at the point where i cannot even playback anything. When pulling up any session the CPU meter will just be throbbing, random restarts it might go away, but will still get 9173 error. This is driving me nuts... Any suggestions? ABout to do a clean re install of PT 11.3, see what happens. Have already ran disk repairs, deleted prefs, don't know what is going on. Screenshots are below. Thanks guys
