Second video card not being detected

[monster10888]

I just upgraded to Win 10 today. I have a GTX 970 that runs my main monitor and use my older 570 to run my second. I did a clean install of the drivers (using the stickied guide) but I can't get windows to detect my 570, therefore unable to put a picture on the second monitor. The drivers for the cards appear to be the same (355.60) so I have no idea what to do here. Anyone know what I can do?

Yea everything worked well before, when I was running Win 7.

Windows 10 is breaking a lot of working Win 7 / 8 installs. On launch day, SLI users were SoL for example and every time a user reinstalled working drivers, Win 10 would resintall the bad driver right over it. You can install the nVidia driver 22 times and Win 10 wrote over it. With Win 10, WU installs all hardware drivers, which is the main reason why we have recommended all of our users do not install Win 10 .

What happens if you connect 2nd monitor to IGP ?

Plug both monitors into the GTX 970. The 570 is not going to do anything even under Win7 but act as a video port. The GTX 970 is fully capable of driving both monitors.
