I have a ASUS ROG GL552VW with nVidia GTX 960M. I tried to overclock my graphics card to a limit but unfortunately, when I opened GTA V, after some time of loading, the windows crashed with the modern blue screen of death (https://upload.wikimedia.org/wikipedia/commons/a/ab/BSOD_Windows_8.png) with error saying something about Video... The laptop restarted and the graphics card default clocked on its own as was to be. Since then, I am suffering from lags even in those games which used to work smoothly earlier (especially while driving). I tried resetting the windows but had no luck. Please Help... The lags are sometimes intolerable
