ARAM [Crash] Possibly Client! >.>

So, whenever I get into queue, everything is fine in ARAM. But then, when everybody joins, right before champion select screen, my game decides to crash EVERY TIME. I don't know what's wrong but its annoying because every time, it counts as an "abandonment" or "decline" so I have to wait like hours until I can join a queue. Thanks if you respond :P

1. Join ARAM
2. Wait for people to join and wants to take you to champion select
3. Champion select doesnt load and your game is not responding
4. Task manager out
5. Try to log in to League like 4 times until you get in
6. It wont let you reconnect or join another game because you "abandoned" it
