Grey Screen into crash on ARAM and Nexus Blitz

My screen will randomly go a weird tan/grey color for about 10 seconds, then tab me out and play the last 10 seconds of game sounds in .5 seconds, then crash. My drivers are all up to date, my connection is fine notable pc specs: Ryzen 1600 16gb ram gtx 980 so it's not like i can't run the game.

Is there a crash dump i can screenshot and send in on a ticket or something?
