Where is your graphic card ??? The AMD Ryzen 7 2700X has no iGPU.
You NEED a graphic card to be able to output anything on a monitor

That worked thanks. But should I be worried that the card is over the connectors at the bottom of the board?
Go into the mobo manual and check what slot is PCIE Gen 3 x16 and keep your GPU in that slot. Although the difference in performance between Gen 3 x16 and Gen 3 x8 is minimal especially for a GTX 970, You're better off with x16. If your x16 slot doesn't work then keep it in x8 but keep in mind that the mobo is probably broken somewhere for that to happen and newer GPUs will NEED atleast PCIE Gen 3 x16 slots to perform as intended.
