I got this motherboard and when I tried to install it and turn it on my graphics card did not work. The integrated graphics card worked but my GTX 770 did not. I can see the fans come on and I know it's on but there is no display when I plug it in. I tried to disable the Intergrated graphics in the BIOS and set the proper PCIE slot to the default but nothing happened. Can someone tell me how to set it up?
