Game is unplayable but not crashing when started with Yasuo

I have played a bunch of games since buying yasuo a couple days ago. Every single game i have played i have to restart my computer because the game freezes. Where the players spawn or get zapped down. I have tried waiting for it to load, which doesnt happen. I cannot alt-tab out of it because when i do it's still on my screen. The thing is i have tested it with other champions and nothing bad happens. So i guess it is something just up with Yasuo. I am going to try re installing, but i wanted to report this before i did so.

Also, i can't screenshot it because my computer becomes un-usable after it happens, i could get the screenshot but not place it anywhere.
