GTX 770 detected, but not working

[Dimeman]

Recently built my brother his computer, with an I5 4570, Reference GTX 770, Gigabyte Z97-HD3, Corsair TX750, in a Corsair Spec 01 and with a Seagate 1TB Hard Drive.

Got all of the drivers. I went and downloaded Geforce Experience and got the game ready drivers. My brother wanted to play ARK: Survival Evolved and I know even with a GTX 770 it'd be playable. Apparently, the game is only detecting the intergrated graphics from the I5 4570 rather than the actual physical GPU. Any help is appreciated.

have you set the 'GPU to initialize first' to pcie or peg in the bios?

I replaced the 770 with a 1060. Same issue, I can't boot into the bios though without black screen it just goes straight to windows login. But I didn't change it to initialize first.
