Computer Freezes when game starts

Hello!!

I've been having problems trying to play league. I recently updated my laptop to windows 10, version 1607. Just now, I started up a ranked game. I had no problems till the game popped up, and went to 0:03. My laptop stopped, and the Youtube video I was watching froze and the sound started repeating. I thought my laptop was having problems, so I tried playing other games, and it worked. Could anyone help me with this problem??

Sorry for my bad english...
