URF Crashes My System In Champ Select

So I seem to have this issue with the old system of picking champions... Legend of the Poro King and Urf both crash my whole system.. I have to reboot my pc because it just locks up my system. From what I can tell it happened every time we got past bans and had to select a champ in poro king and now with URF I played a couple games and the third game I had to ban... As soon as I had to pick my system froze... So.. Yea.

What is this madness?
