After turning on the PC, no fans are spinning (all of them are definitely connected) and the red CPU debug lights up. after about 5-10 seconds the VGA debug lights up. After the VGA lighted up it stays this way until I turn of the PC. When connecting to a Monitor it doesn't even recognize the channel (tried on 3 different monitors with either DisplayPort or HDMI). What should I try now to solve this ? The CPU seems perfectly fine (no bent pins) and all PCIe receptors on the GPU are fine. Also tried with another good GPU

My specs are:
Ryzen 9 5900x
MSi MAG Tomohawk B550 with updated BIOS
RTX 3070
850W PSU

I have another psu to check with. Not a GPU different then 3070.
Is it normal that the cpu fan is not spinning when the diagnotics are running?

There is no bend pin on the CPU. The CPU led als goes off so i think there is no problem with it.
What do you mean by check both end of the cable? Continuity?
