Hmm, bit off-topic here, but do we really need the .pdb files? After an update, I always scan through the PDN folders, and remove them. I've not had the men in white coats knocking on the door yet!

Rick,
You know better than myself with these things, but I have had a few failures with the NVidia site, in that it identified my GPU but failed to install correctly when downloading their selected driver. Never had any bother with the NVCleanstall application

Have you tried NVCleanstall from https://www.techpowerup.com/download/techpowerup-nvcleanstall/
Works great, and picks the correct driver for your GPU
