Got this motherboard today with i7 3930k CPU. I've got error code 97 with MSI r9 390 8 GB card, gtx 780 and MSI 970 no post just black screen, but when I'm using the msi 5700 series GPU it's post and no problem at all. Bios is up to date. I haven't tried any diagnosed. I need your opinion before I mess with it.. thanks in advance
