Hello there. I am using an AMD Radeon HD 6900 series and usually when I try to start my computer I get white lines in my screen for which I have to turn computer off manually and then start again untill the white lines disappear. When I actually start my computer and log in whenever I start my internet or log into a game the screen starts flimmering lines and then the screen just turns black.
If any way you could help me please reply asap because I really do not know what to do.
