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

Any help would be appreciated!
