Game freezing mid game. Regular bug splats. [CLIENT] [CRASH]

I dont know why but about two patches ago my game suddenly started freezing mid game every four or five games, causing me to need to turn off my computer to fix it. Also I regularly get bug splats while using the client. I have tried reinstalling three or four times and nothing changes. As a result I have been getting reported, losing LP from remakes and generally getting frustrated. Riot please fix your game, I send my bug splat reports every time it happens. [sg-janna]
