Long story short: 

Code 43 error on laptop after installing drivers. Laptop itself has intel integrated graphics and also Nvidia GeForce 820m integrated into motherboard. The Nvidia 820m works fine(with code 43 error) when i unplug the GTX 680( which is mounted on the Bangood mini-pcie adapter). However once plugged in both the Nvidia Geforce 820m and the Nvidia GTX 680 GPU have a code 43 error. I've tried unistalling and re-installing drivers. The versions i've tried are: 376.33, 376.19, 368.81. I've used DDU to clear the drivers as well (in safe mode) but that seems to have failed as well. 

Notebook Specs are:
Ram: 8gb
Processor Intel I5 4510u 

GPU: Nvidia 820m 2gb

 

On another note: Also trying to use internal LCD Screen & unable to switch to UMA Gpu instead of integrated (may cause issues) since the BIOS does not seem to have the option (either that or i am blind). 

this could be due to resource allocation. the laptop can't use both gpus at once?

try disabling one gpu then installing driver/reboot.

if nothing works, you will need to disable the dgpu with an override.

diy egpu setup 1.30, check it out could help but it costs 25 usd.

I am using an EGPU on my Lenovo Y510p (http://imgur.com/HN51mJj). I have hooked up the GPU and booted up windows and I got the error 43 message (http://imgur.com/QfhThfh). I a using a Corsair CX600PSU and the V8.0 EXP GDC Beast EGPU enclosure (http://www.banggood.com/Mini-PCI-E-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1011222.html).

Disable automatic driver installation

uninstall dgpu and egpu drivers

download old nvidia driver ( i used 376.33)

reboot

install old driver

egpu should now work, it did for me.

if not, fiddle around by disabling gpus and using different drivers or gdc beast delay.

also, check if the egpu shows an image in BIOS.
