    Hey guys and Gals,

    The answer to this problem is probably obvious but I can't for the life of me work it out.
    This is an old windows 7 machine that could probably do with a format, I am sure this would fix the problem but I would love to understand why this is occurring.

    I have a bog standard integrated Intel GPU.
    And
    GTX 780

    I have the monitor attached to the GTX780 and it displays the desktop. No worries. BUT!
    The control panel does not see the GTX780, instead it shows only 1 GPU Intel HD GPU.

    Obvously the GTX780 is working as I can see the desktop on the monitor!
    But I cannot install the Nvidia drivers because windows cannot see it, I get an error when the driver starts to install saying it cannot find a compatible device. I am so confused!?

    I have tried showing hidden devices on the device manager but no luck.
    I have tried scanning for new hardware/changes but not luck.

    The reason I am chasing a solution is due to black screens I get when I try to run any 3d accelerated games.
    I am pretty sure this is due to the drivers not being installed properly and the great intel/nvidia mixup!

    Can someone point me in the right direction.

    Have you tried just updating the driver from Device manager?

    The GTX device is not detected in the device manager to update it. I might assume the Intel HD device that is listed "might" be the GTX card with Intel drivers but I doubt it.

    Is it possible the GTX hardware has the Intel drivers mounted to it?!?

    that won't be the case, have you tried just disabling the Intel in the BIOS?

    Not yet, I would assume this would just remove the intel GPU as an optional GPU in the device manager, the monitor is plugged into the 780 so I am still super confused as to how I am getting any display without the device being detected. Happy to give it a try. How would this approach solve the case of the missing GTX780?

    Just an update for anyone interested. I installed windows 10 on a separate internal drive and it was detected and worked fine.
    When I switched back to windows 7 OS it picked it up and started working fine.

    Seems it was a Win7 OS issue that was never actually identified.

    Open Powershell and show the output of this:

    Code:
    Get-PnpDevice -presentOnly | where-object {$_.Class -like "Display" -and $_.Manufacturer -like "NVIDIA"}
