I recently built my own custom PC. I had the help of my experienced cousin and PC part picker. when I booted my PC everything turned on and was running good, except for the most important part, my GPU. I have tried everything to make my mobo read my GPU, but nothing has worked. I even tried putting my GPU in another computer to see if it worked, it did. I know my GPU works so I figured it was my mobo. I got a new mobo and still had the same problem. I've spent so many hours trying to get this to work, please help.
mobo: H110M-PRO-VD-PLUS
GPU: GIGABYTE GeForce GTX 1070
CPU: Intel Core i5
PSU: Corsair RM550X
OS: Windows 10 x64
