I have a Dell inspiron 15 3521 in which there are two Graphic cards AMD(radeon 7670M) and INTEL . One time I was playing a video game with the AMD one , suddenly the game turned colors and it ended by a BLUE screen of death. I couldn't install the graphic card and every time I try it shows the blue screen . I have tried every possible method to Fix it. The weird thing is that when I install AMD driver , INTEL uninstall itself automatically. so I had to do a system restore every try I fail .What should I do? Is my graphic card damaged?
