Well, CUDA on the restored GTS450 is too old and I migrated to P106-100.
That card (Pascal architecture) requires the non-free driver.
I have difficulties with nonfree driver selection.
Is it a simple way to switch between free and nonfree driver?
Old driver installations’ problems, may be?

NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
