I am having a bit of trouble with one of my PCI-e slots (i think). I recently realized that my motherboard was not detecting my second GTX970. I tried looking at my Bois for clues and rolling back to a different version of Windows 10 (i had literally update the day before), but still nothing. I even switched my graphics cards and they both work. I am out of ideas, is there anything else anyone can think of? I really do not want to by a new MB.
