Hoping someone could tell me what's going on , so I have two GTX 970s paired with the ASUS ROG STRIX Z390-E Gaming and a I5 9600K. One of the GPUs will have no issues in either of the slots. When I swap my second GPU in place, it's not detected in the BIOS at all, no matter if it's PCIE 1 OR 2. I know this card is good because i've had it ran on another setup and it displays video just fine. When I put them in together, most times it'll only detect my card that does display , other times the display won't output until I remove the one that doesn't display anything. I have updated my bios and installed Nvidia driver. Thank you!!
