[CLIENT] Keeps crashing during games

As the title states, the client keeps crashing. Over, and over, and over again. I've uninstalled, reinstalled, restarted my comp, ran it as admin(only delays the inevitable by like 10 minutes) but nothing seems to work

1. Open League
2. Log in
3. Get into a game
4. Wait for the inevitable

For me, it's been 10/10 that I experience this crash, more than once per game. Haven't had this problem till this recent patch. Running the game on WIndow's 8.1
