I just installed a second PNY Geforce 950 card to run in SLI. Both cards run just fine on their own. When I plug the second in, and enable SLI in Nvidia control panel, the image shuts down, and windows restarts. I can get back into Windows only if I disconnect the second graphics card. I have tried two PSUs (one 700w, the other 750) and get the exact same behavior. It's a brand new clean install of Windows 10. I'm wondering if there's not a BIOS setting that I need to play with. Any thoughts?
