I am trying to build a computer. I finished it with an i7-6700 and evga gtx 1050 ti and a msi mortar B250M but for some reason my computer won't detect the graphics card.

On the motherboard, it has a pci-e4 and a pci-e1 slot. I put the 1050 into the pci-e1 slot because it doesn't fit into the pci-e4 slot (because of my case).

Please help
