ASUS Prime Z270-P cant detect any GPU

[robisq]

Hi

I have been using MSI and Biostar motherboards without any issue. I just got a ASUS Prime Z270-P and i have no clue why it cannot detect any GPU and keeps loading on the default CPU Intel Graphics. Ive tried different types of GPU connected on risers and to the PCIEs but it always sticks to the CPU Graphics.

Hope anyone can give me some advise, cuz im been researching a solution for hours... Ive tried going bios setting and changing primary graphics to PCIE but still didnt work..

help....
