Hi. I need your help. I bought all new spare parts and assembled the computer. When I connect the cable directly from the motherboard, the screen works, but when I install the video card and connect the cable from the video card, I have a black screen. Has anyone faced such a problem?
motherboard - MSI Z890 Carbon WI FI
video card - Msi VANGUARD rtx5070 12GB
Have you checked the power to the gpu, checked the gpu seating, looked in bios and set it for PCIE instead of auto or igpu, done the drivers, or put the gpu into another pc?
Do the fans come on when you start the pc and the GPU posts? when you say all new spare parts, do you mean used? Do you have access to another video card to put in the computer and try that?
