System crash from cold boot up?

Hi all, when I shut down my computer and then start it up fresh next day, I get an immediate crash and automatic restart. Then it boots normally. Afraid one day it may not reboot normally so trying to solve the issue now before it gets any worse. Any ideas as to what could be causing it from this crash report? Unfortunately it's Greek to me.

BIG thank you to all the tech geniuses!
