Game exit windows crash.

Good Evening,

well seem to have stumbled on my first problem. I am unsure what is causing this to happen but this is what is going on. game starts up great! can play as long as I would like :) but if I run into the problem when I need to google something or just by alt+tab or even just exit the game, my system crashes. I will receive a blue screen saying that windows needs to restart and gives me sad face :(. I don't like sad faces can someone please be so kind and assist me.

Thank you.
