Game crashing constantly

Hey so I've been having this problem lately. I log into the game, everything is fine. As soon as the game begins, league crashes and i have to exit the game and relog and reconnect for several times before it loads back the game. Also when im almost at 100% loaded it crashes again saying that there is no connection and i have to restart. Every time this happenes it is registered as AFK and it is really annoying because I'm getting tired of 20 minutes leave busters. What I'm mad about is that my PC is fine, the internet is great and there are no other programs running at the same time. Anybody else having this problem or it's only me?
