Ok, so I built a new pc and when I press the power button everything starts working except the gpu. My cpu and case fans spin but my gpu fans won't spin and when I try to plugin a display, it won't show. I can't do anything in BIOS because my only display ports are on the gpu. Once I got my new pc, I didn't get a new gpu and used my old one (RX 570) which has always work just fine, any help or solutions?
