2nd video card will not work after Geforce GTX 950 install

[codeview]

Everything was working fine when I had a Geforce 210 and Geforce 9500 installed. Now that I have installed my new Geforce 950, my second video card will not be recognized when installed with it.

I've tried both the 210 and the 9500 (see screenshot below). The Nvidia drivers are the newest available and when I try to use the Device Manager's "update driver" feature on the second video card, it does work...but then the 950 is not recognized 🙁

Any ideas? Thank you for your time.

My work PC uses two different genetation Nvidia cards and I cant use Windows update for the drivers. I had to download both drivers from nvidia and install them. Its been a while, but I think I also had to uninstall the driver Windows installed.

Thanks for the post. I have tried installing the driver for each video card (the drivers downloaded by doing a manual search on Nvidia's driver page) but whenever I install a driver for either device it takes over as the only driver, so the 950 ends up running on the 210 driver (or that version anyway). I have 1 monitor connected to the 950 and 2 monitors connected to the 210...and I can not get the 210 monitors to display anything.

Alright, after some more Googling I seem to have found my answer. Turns out Nvidia's latest drivers do not include support for the 200-series, as well as others. I didn't realize this. And also didn't realize you can't have 2 different video drivers installed at same time.

So, for my 3 monitor setup I will have to run all 3 monitors off the Geforce 950 (or buy I newer second video card so that both cards can use the same driver, but that is not necessary in my case - I was just wanting to run the 2 monitors off the second video card so that the 950 wouldn't lose frames while gaming...but I will just disable the 2nd and 3rd display when gaming to avoid that).
