Machine specs:  HP Z820 - zeon e5-2690 48gb ram quadro k5000.  Since the recent updates & complete wipe of the system & fresh install, Premiere pro CC crashes regularly without any pattern.  Using MXF files while editing if that helps-i did read a thread about that - but it was old.  This is a new problem.  The event viewer information:
