I have a i7-6700 and a asus-170A and a GTX 1070. When my graphics card is installed it won't give any signal to my monitor when I plug the VGA into the graphics card or the CPU. I've tried a HDMI cable aswell. But when I take the graphics card out my computer runs perfectly. I've tried downloading Nvidia GeForce experience and it won't download cause it doesn't recognize that I have the GPU
