My game has started crashing today.

It worked fine last night and all days before. I tried to play a game today and everything starts fine, go through champ select, then I get to the loading screen. I'm waiting and waiting and waiting and its been about 10 minutes and this 1 person on the other team has been at 99% for the last 8 of those min. SO i start thinking maybe its my game. so I restart the game it loads i reconnect and sure enough it was just my game, they had been in game the whole time almost, I had 3k gold racked up when i joined. So then i start playing and couple minutes in my champ just stops moving, but the timer is still going, the dragon still came swooshing in, But i was unable to do anything and my team wasn't moving either. But that was only on my game too as i restarted my game and reconnected all over again and they had still been playing. So i start playing again and it does it again, So i repeat for 1 last time before the game was over and of course it crashed again and then took me straight to the results screen, where i was able to get there with everyone at the same time and talk to everyone. Soo I don't really know. Any ideas or thoughts would greatly be appreciated.
