MacBook Pro keeps restarting by itself
So occasionally my MacBook Pro (13 inch model) likes to restart itself and go to the grey screen that says (your MacBook restarted because of a problem). I have no idea what's causing it. The hard drive is brand new (replaced it yesterday because the store that sold me the Mac said it was corrupted). When I pull up the summary of the report this is what I get:
*** Panic Report ***
