Built my first computer but it wont connect to the monitor

So on friday i built my first computer, i turned the power button on fans are spinning and what not. (Build info here https://pcpartpicker.com/list/jHNgjc all my parts and what not) So whenever i tried connecting to my monitor just standard VGA to VGA (Through the motherboard) nothing happened, couldnt get it to work. So then a google search told me i should connect it to my graphics card which i then realized my graphics card wasnt a VGA it was DVI-D Dualink port. So 2 more days pass as i order one off amazon (the adapter to connect the two) it still doesnt work. Then i noticed when i power the system a redlight on the motherboard appears the VGA light. In the motherboard manual it says the GPU is not connected/not found. So i assumed that was preventing me from connecting to the monitor. and then a another google search revealed to me its 99% because i dont have the drivers for it. And how can i get drivers or do anything if i cant even connect to a monitor. So please if you guys have any insight into this i would greatly appreciate this.
