So I made sure my motherboard and PS was compatible, and it is. I literally took the 5600XT out, and put the 3090 into the same port. ONLY difference I can see if the pins on the cables from the PS. The 5600 had an 8 pin and 6 pin, the 3090 has slots for 3 8 pins? (i believe. Im a noob, and didnt even build the pc to begin with lol.) Anyone have any advice as to why absolutely no display. And yes i tried the other hdmi and dp ports. Thanks in advance.
