so my computers screen has been turning white (like i have the gamma up or something) and for some reason whenever i push on the laptops screen it goes away, i know for a fact this isn't a graphics card problem as whenever i plug in a second monitor with a HDMI cord that screen doesn't go white at all, i do play a lot of high CPU consuming games, can someone please help me this has been going on for a while and i am sick of it
