It's windows 10... I had the same issues, I installed windows 8.1, everything worked fine.

Hmm do we know why it does it but? It must be driver related then surely as the OS core is mostly the same.

Hi Mate, Thanks for the reply. I have tried to disable the 840m and I still cant load the manager and all games revert to the onboard Intel. If I plug a monitor into the external card I get no display.

Laptop Specs:

Lenovo Z710

Intel i7-4710MQ 2.5GHz

8GB Ram

1TB HDD

Nvidia 840M

Windows 10

Egpu Specs:

PE4C-PM060A V3.0

Nvidia GTX560Ti

Now the issue I have, I can get all the GPU's to show up fine in device manager and If i play a game it will use the 840M, However I cant change what card I use as it wont allow me to load the Nvidia control panel. Here is a screenshot of my GPUz and device manager.

Is there something I'm missing here? I have wiped all the drivers and made sure there was nothing left on the system and used to latest DESKTOP drivers with no luck. Any ideas?
