Question Drivers/System Don't See CUDA Cores

A system I have been working with for a while for some reason doesn't seem to recognize some aspect of my nVidia GeForce GTX 970 graphics card, and I don't understand why. Programs that use CUDA cores claim they can't find them, and some programs, like Resolve, won't even start without it.

I download the latest drivers from the nVidia site and tried to update the drivers to see if that would help, but the drivers report that they are not finding an nVidia CUDA card.

The video card otherwise appears to be working, and delivers signal to the monitor.

Are CUDA cores separate from the main graphics drivers on nVidia cards? I don't understand why the card appears to be normal but programs and drivers don't see it. The card is presently running off drivers installed by my operating system

Any ideas? Virus? Thanks for any info on this.

OK, well I installed that, and things got worse. I still have video, but programs that once worked at least off the CPU when the GPU wasn't available now just crash. DaVinci Resolve still does not see CUDA cores.

I'm not sure if I can bypass the problem with a Radeon card. Some programs favor CUDA cards however. I don't understand why something that was working perfectly normal disappears from the OS.
