    Samsung laptop does not recognize my NVIDIA graphic card


    Hi everyone, first of all i want to apologize for my english, but i tried to fix this problem in all the forums in my language and nothing.
    Ok so here is my problem, i just re installed my windows in my 2 years old laptop, i installed windows 7 home premium 64 bits.
    there were some drivers that my laptop did not installed so i did it manually, after all this i realized that my NVIDIA graphic card does not appear in the device manager, it only shows my intel HD graphics. i've tried a lot of possible solutions i found in forums but still nothing. i tried to install the driver of the nvidia graphic and it says something like this: this graphic driver couldn't find a compatible graphic hardware.
    I hope anyone can help me with this problem i would be very grateful.
    Here are my computer specs:
    Samsung NP300E4A-S05CL
    NVIDIA Geforce 315M (optimus)

    That's really abnormal, the fact that a Graphics Card just "Dissappears" Is properly seated?

    Apparently though, some laptops disable the NVidia Card on Optimus setups, when it is powered on battery. If it isn't already, plug in the cord and restart.

    Also can you show us a screenshot of device manager?

    Download the Nvidia driver from your laptop's manufacturer website..

    And about the drivers i've downloaded the lastest version of my NVIDIA from both NVIDIA and my laptop's manufacturer website, it's not about the drivers, is my laptop that just don't recognize my NVIDIA graphic card and just the intel one

    Does the card get detected by other OSes? Perhaps try using a Ubuntu Live USB

    Some laptop manufacturers will alter the hardware ID of the video card so that only their custom driver will install. Especially when the laptop has dual graphics. This done to ensure that the dual graphics work as advertised and switch on the fly when needed. The altered hardware ID is what causes the "this graphic driver couldn't find a compatible graphic hardware" message. If you have installed other drivers from say Intel, you may have to uninstall them before installing the driver from the laptop manufacturer.
