Uninstalled GPU drivers now doesn't work

[Sirjarjar]

Hey all I have a gtx 970 and uninstalled drivers through programs and features. Now my screen goes black when I connect the display port into the gpu or connect the vga cables onto the gpu but it works fine when it's connected to the motherboard. I took out the CMOS battery. Any help is appreciated thanks

I fixed it by putting my gpu on the 2nd slot. Thanks
