Hello guys, my new RTX4080 FE only flashes the LEDs but doesn't deliver any picture. I have already read online that there is supposed to be a bug where it doesnt light up until the OS, but it doesnt light up at all. I have tried the original cable and one aftermarket one, but both dont do the trick. Also all the software is the latest available. Here is my Setup:Ryzen 75800X, Gigabyte B550I (In Bios set to: "PCIe: Auto", and "Legacy Mode"), PCIe 3.0 Riser, Corsair SF750 Video of the problem is attached Any help would be appreciated!

Occasionally these risers create problems near PCIe 4.0 parts. Switching to 3.0 mode might help resolve the issue.
