Client Freezes

I know im not the only one who is facing this issue in the League world. but I can be in the middle of a game and the Client Stops, no sound, no video just stops. Sad part is you cant even Leave the game to restart it. Its starting to happen back to back I cant play a game with out it happening. So im faced with these Leaver Busters that the Client forces, Riot I beg you fix this before i move past League. Im tired of waiting to play cause you guys haven't fixed these issues.
