    Nvidia Geforce 840m Problem

    I have bought a Lenovo Flex 2 and installed Windows 10 Enterprise 64 bit on it. My laptop has Nvidia Geforce 840m GPU. I have downloaded the latest version of drivers include main driver and Game Ready drivers:

    358.50-desktop-win10-64bit-international-whql (Game Ready Version)

    But I have problem in running graphic games like call of duty an need for speed and etc.
    When I checked display adapter properties I saw that the graphic card didn't detected and Microsoft Basic Display Adapter is default and my geforce VGA is not listed.
    Here is screenshots of my problem.

    However I have installed my graphic card successfully bu Geforce 840m is not detected as my default VGA adapter. Thus I have various problems such as:
    -Games are not running properly
    -Screen brightness function control (F11 and F12) didn't work
    -and so on ...

    Sort out these missing drivers first. All may become good then. Go to the Lenovo site and download the correct drivers for your Lenovo.

    Graphics controllers and other devices depend on system devices that are part of the chipset. If these devices are not installed or driver doesn't work well, then other devices such as the graphics controller are not detected or work properly. Download the latest chipset driver directly from Intel (assuming you have an Intel CPU), install it and restart your computer. Then try to install latest GeForce driver from nVidia's site. Use the mobile version of the driver of course, since you have a notebook.

    The Graphic Card 840M is installed, your probelm is the Intel card is not installed, don't worry its simple you can watch a youtube video how to install a drive or just right click and update driver, if its not possible, then right click properties and on one windows you will see ID, go to hardware ID, copy it paste it on google chrome and find you graphic card driver. If its to complicated just watch a youtube tutorial "How to install a driver".

    P.S. Right click on Microsoft Basic Display Adapter (It should have two cards, maybe its a but that its saying 4GB or VRAM) and not on the two missing, the two missing are not the Intel or the Geforce graphic, they are different pobably a bluetooth driver, or maybe somethings like keyboard schortcut, or maybe a card reader, you can also find them on the two ways i told you.

    AND DON'T FORGET When you open a game you need to right click and Run with graphic processor > High Performance... if you don't have that option i'm sure you will have it after you have installed the Intel Graphic Card.
    Also go to power option and select High performance to get more FPS. If its still not working or you have another questions send a message to me.

Windows 10 is saying that it "has stopped this device because it has reported problems" for both my Intel and Nvidia graphics, and even Portal and Little Inferno are choppy so it's definitely not using my dedicated graphics. Thanks
