When i try playing any game, the game just crashes while i could play it smoothly a few days ago. It all happend when i gave my pc case a wiggle because it made a weard noise ( I know i shouldn've done that) and then my whole game and pc crashed. After that i couldn't play any game it just went all pixely and white and other colour squares started popping out of my screen i think it is my gpu and i have a picture on my phone if you want to see it. Please anyone if you know how to fix this please help me Sueni. Oh and i even tried reinstalling the game and reinstalling the drivers but nothing worked and i installed the new drivers before this all happend.
