Built my pc not long ago, seemingly no problems playing league of legends for weeks until today my graphics card has crashed in-game. It started happening frequently today to now when it just about crashes every single game, whenever i get into a game. I loaded on the drivers, including those specific to lol, yet it still happens, just loaded into a game the fans went mental and it crashed/screen goes black. Anyone know what could be the fault here or heard of similar? i find it odd that it only started today..only 3 week old gpu..

I can use the pc as normal for all my daily tasks but i haven't really tried anything graphically intensive like league to see if it also crashes it.
