This post contains the instructions on how to fix the latest 460.79 Nvidia Windows driver. The reason for the problem is that one of the DLLs (nvml.dll) that the driver installs is corrupted. Here is what you have to do in order to fix the problem:

Download nvml_460.79_win10.zip from here: https://mega.nz/#F!2VskDJrI!lsQsz1CdDe8x5cH3L8QaBw (MEGA)

If you want to check the integrity of the downloaded file, please use the following hashes:

Extract the file nvml.dll from the .zip archive you have downloaded in the previous step, and then copy it to the folder C:\Windows\System32. There will be a file with the same name here, so you have to overwrite it (you will be prompted by Windows are you sure, blah, blah, blah)

Note that this .dll is the original .dll from Nvidia (it is still digitally signed by them). If you are really paranoid, you can download 460.79 drivers from Nvidia, then use 7zip to open the .exe and extract the dll (you will find it at 460.79-desktop-win10-64bit-international-dch-whql.exe\Display.Driver\nvml.dll), and then copy it to the C:\Windows\System32 folder.

What does GPU-Z say? Is OpenCL enabled on all cards? If not then you have driver install problem -> Uninstall current driver with DDU, reboot, install driver again
