Can't create a slide show, because drivers of the graphics card are outdated

You may have some issues with previous GPU driver installs that left crud behind. Consider uninstalling the GPU driver, then installing a fresh new copy using NVIDIA GeForce Experience, select custom for install type as to cause a clean install.

What is the exact error message?

I'm using an eight-year-old computer that doesn't have a graphics card, just on board graphics. I haven't been able to create a slideshow with Lightroom for quite some time. However, I can create a PDF slideshow. If you don't have Adobe Acrobat you can download Adobe Acrobat Reader to display the slideshow, and it works quite well. Not the ideal situation, I realize. But it IS a solution that is available.

Thank you.

IIRC that GPU is WAY OLD. Like my GTS450.
