I have a formula V and have been using the on board graphics for over a year,

Tried adding a MSI R9 290X video card, but the motherboard will not recognize it.
In the bios have tried forcing it to use the PCi-E card, but every time I save and reset the it automatically changes back to "AUTO"
In the NB Config it says "not present" for all the PCI-E slots. I have tried all 3
I have installed the video card drivers

I have looked in the MB manual for any settings I am missing, but I cannot find anything.

Any bios settings I am forgetting?

Thank you
