I recently purchased a dell inspiron 15 3521 with intel hd 4000 nd amd radeon hd 7600M. The problem is when i play any high graphics game, a continous strem of hoizontal lines appear on the screen from top to bottom. Also i am not able to get the catalyst control center options in the pull down menu. In addition to that, the real radeon driver installed is 7600M series. But when i check online, it says 7670M series /
Does anyone have any solutions regarding above ?
