Black screen when Switching from MSI Radeon 7700 to EVGA GTX580 on ASUS 990fx v2 running AMD 8320

[pcookgeol]

I am hoping someone can help me with this...
I am upgrading my gpu from an MSI Radeon 7700 to dual EVGA GTX580s that I plan to SLI... I uninstalled the Radeon software and drivers from my system, removed the MSI card, installed one EVGA card in PCI-e v2 slot 3, provided 8-pin power (6+2) and restarted. Connecting one monitor with DVI-HDMI and one monitor with HDMI-miniHDMI. I do not have the Nvidia install disc. My monitors are blank (black)... How do I fix this problem?
ASUS Sabertooth 990 FX v2.0 (current bios)
16 gb ram
AMD 8320 fx chipset
Thermaltake 750w Gold
Dual Viewsonic VS15703 monitors
Windows 10
