PC's first boot doesn't start

[Mattes22]

Hey,

the build I'm working on rn doesn't start properly. No OS is installed and I don't get any video output. Everything should be connected properly:

The build is:

Motherboard: TRX40 AORUS PRO WIFI

CPU:                 AMD Ryzen Threadripper 3970X

GPU:                Gigabyte AMD Radeon 5600 XT

RAM:                4x Kingston 32GB 3200MHz

PSU:                 850 Watt

Hope to get advice soon and thank you in advance.

make sure that your hdmi/dp cable is working. same with the ports on your monitor and GPU. Make sure the video cable is plugged into the GPU.

For some additional info:

- The CPU_LED is shining red on start-up and no other leds light up

- We only get fan-spin and nothing else

- We originally had reg. ECC RAM installed, but later found that to be incompatible. We have now switched to 1 standard DDR4 DIMM

- We tried the Q-Flash Plus procedure, but couldnt find any information as to how to rename the BIOS file

- We tried two different GPUs
