I see posts following this that are pretty recent, thank God. Can't believe no resolution. I have been struggling with this off and on for a week. I haven't posted a question in any forum because I know it should be a simple BIOS setting, I'm just not familiar with MSI. I am working with a mint (yes) MSI Z97 Gaming 5, and all 3 onboard video options (vga, hdmi, dvi) are working fine. However, nothing is seen in any PCIe slot in any combination.
I understand x16, and the 8/8/4, and all that This board doesn't see anything. And I mean it is in brand-new condition, I broke the factory seal. And I have plenty of PCIe devices that I have rotated around. The most basic of things is, it will not even detect a GPU in Slot 1. This board has 3 x16 slots and 4 x1.
Even if you don't have an answer but maybe some thought or experience, post here and keep this thread alive until some Guru All-Seeing member comes around.
