[CRASH] Still Can't Load Into Any Games

So I've uninstalled League again, set my computer to an earlier restoration point, and it still doesn't connect me when I try to play a random bot game. After my recent game (my fifth) I've been put on the AFK/LeaverBuster watch, which is pretty whack. I would greatly appreciate any help to how I can fix my game from crashing on me so I can continue to enjoy playing. That'd be really great.

Update: Managed to load into a game, but as soon as I started to move it froze and crashed on me...
