nvidia card not detected after changing hard disk

[xhauzz]

i recently changed a new harddisk at a shop overseas and didnt ask them to migrate my data from my old hard disk to this new one. they installed my win 8.1 for me. now when i want to play games my games only detect my intel 4900 card instead of my nvidia GTX 860M

i tried using the nvidia control panel and even disabling the intel card nothing works.

when i disable the intel card the games only detect microsoft display driver instead.

i am using an ASUS ROG G551JW laptop

Go to the ASUS support site and install all the drivers for your system from there. Does the nVidia video card actually show up in Device Manager?
