League crashed multiple times.

Everytime I tabbed out of the game it crashed, it said "make sure you have the latest drivers updated ". All of my drivers are up to date, so that's out of the question. I clicked the rejoin button but the game Instantly crashed. The only thing that fixed it was to restart my laptop. I did this everytime it crashed. I sent a ticket to support but they just threw me to some link and said here look at this... wow.
