No display with new computer

Ok so I bought a new graphics card. Processor, motherboard, and ram. I'm using the rest from my old computer
I checked them all in partpicker and it said everything was compatible
When If I turn it on without my graphics card everything works fine but when I turn it on with the card there is no display on the screen... The lights on the card turn on and everything the fan starts spinning but then stops and still no display from either the motherboard or the graphics card.
Also I tried going on my bios but that starting screen looks like it's too big for my screen and when I get into bios everything is black and I only see my mouse which is like oversized on my screen
My parts are
Gtx 970 gaming G4
Gigabyte z97x-sli
Intel core i5-4590 lga1150
Evga 500w
