GeForce 435.27 Windows update

Still seems weird that 431.65 works everything newer does not
All the graphics (including 880m) are pushed through the iGPU, maximus somehow switches where the input of what to display onto screen

Setup stopping with error early usually means can't find GPU, something afoot
You are not deleting other INFs from driver folder ? this will cause error
Just replace INF
Another reason is if your GPU exists in an OEM INF, then you need to remove the PCI_ID lines from the OEM INF (as I need to test the modded INFs)

Install via Device manager and see what that says

And yes install latest IGPU drivers as windows updates adds new features

430.86 https://www.nvidia.com/Download/driverResults.aspx/147966/en-us is the latest that Nvidia offers for 840M.

Installation fails even with inf file

Any clues to what the error is ?
 

Did you disable Driver Signature Enforcement ? (Google it)
If yes go to install via Device manager and see what error is

Of course I did. Despite of clean uninstalling drivers through DDU, Device manager tells that some more feasible driver is already installed

Log: setupapi.dev.log

another log after failure of some found driver installation through DM setupapi.dev.log

This can happen if you use "manual installation".

Try "have disk method" as described in FAQ section instead.

DM successfully installs the same drivers, nonetheless 880m is not detected in games. But there is an interesting thing: some games(RE2 remake for example) detect 880m on 381 and 382 installed through Disk method

I finally found the driver (419.34 Vulkan Mobile OE 419.34 Vulkan Mobile) which detects my 880m in all tested games. Only Disk method helped to install this driver and many others successfully. So guys, thank you for everything, now Im happy.

Your system is really an oddball one! Congrats getting a working driver.

Moreover most of the drivers on the site started working correctly...
