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).
