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?
