Hello, I have Asus K53SV laptop , using Geforce 540GTM driver... well I have reinstalled all drivers and tried different methods to fix it , but suddenly my dxdiag doesnt show I m using nvidia , still shows INTEL HD ... and I really want to fix this and make sure my computer is running on geforce instead nvidia, since I m playing games and nvidia would be better obviously. Could anyone help me? Currently I m trying to reinstall both drivers again, already disabled Intel , but after that it said N/a on dxdiag :l
