Yes a tried all ghis shizzle. But nothing changed something. But thanks to all for help and give tips. I wish you all happy holidays.
I‘ll come back with a new setup in the new year.
Can you get hold of another AM4 processor from work or from a friend?
Your PCIe x16 slot is directly connected to the CPU - it's just simple traces to the socket for all of the data pins in the slot - so it's unlikely that the slot is defective unless there's board damage, at which point you'd likely have far more problems showing up than just the PEG lane count.
Yes your motherboard is a cheap, basic model but in the absence of more data the CPU is the #1 suspect here and the motherboard being to blame is less likely. It's why I suggested removing/reseating your processor and inspecting for bent pins, stray thermal goop, or contaminants in the socket itself.
Just remember with AM4 that the CPU likes to glue itself to the heatsink and gets ripped out of the socket with the locking lever still down as you remove the cooler. It's always worth twisting the cooler a little to break the seal before pulling up to remove it.
