I have Asus n53sv laptop and it has geforce 540m and intel hd 3000 also. And when I want to play game there is no sign of geforce. I have installed and uninstalled drivers from booth milion times and nothing. I cant open nvidia control panel it writes that I dont use nvidia display settings or something like that. When I go on device manager it has warning that I have code 43 problem on my geforce gt 540m . I have no idea how to fix this can you please guys help thank you
