Computer shuts off when I load into match
The second, and i mean THE second i enter a league of legends match, whether its custom, bots, aram, dominion, any match at all, my laptop just shuts off. When i play civilization V it works just fine and i can play forever without anything happening, but when i play league it just turns off. I crashed right as the game started, turned the computer back on, and thne when i reloaded back in the computer crashes again. This has been going on for about a month and i cannot find a good way to fix it. Ive updated drivers, rolled back drivers, uninstalled my entire driver and reinstalled it, nothing happens. I cant play league until i fix this or get a new computer and i really want to play league so someone please help me!
