Great, thank you. After adding a GPU if there is still no POST could it mean a BIOS update is required then?

thank you, I will get a GPU. Any compatibility or limitations that I need to keep in mind when i am selecting the GPU?

I have checked the asus site and 3600xt is supported - https://www.asus.com/support/cpu_support
