Last nights update for clash causes Draven to crash my pc

Every time I play draven in pvp modes somewhere between the 10 and 12 minute mark my pc COMPLETELY CRASHES. As if the power was pulled. And worse, I feel like the client mocks that problem as if it knows. Everytime I reconnect into the game before my team surrenders, I get the one, same tooltip. "You can't play without a team - Don't be a leaver"

Its sheer luck that i havent gotten any leaverbuster strikes yet. And Ive tried multiple champs in multiple gamemodes. It only happens with draven and only on summoners rift. This is sickening, and I have no idea what to do except spam full repair on client until it works. Ive "repaired" it 3x already!!!!!

Im completely out of options here!
