Random black screen

I just sorted my graphics drivers out, and as soon as I rebooted, I got a black screen, I tried uninstalling and reinstalling AGDPFix and the Webdrivers to still no avail. I tried reinstalling the entire os, running web drivers and AGDPFix, clearing the nvram to still no avail. I can only get it to boot with nv_disable=1

I have a GTX970 and I'm spoofing iMac 17,1
