Game Doesn't Load

I queue into a game, get through champ select, everything fine here. After champ select, the window with the actual game doesn't load. I am forced to stop the task in task manager (League of Legends Client [the one with old icon]) and then I have to reconnect. This happened to me in my latest ranked game, and it's not the most ideal situation to come into a lane against Fizz while being 12 farm and 2 levels behind.
