Hey guys. I recently built my first system and I am having some problems getting the PCI slot to work. I have tried 2 different wireless PCI cards and I have the same results with both. I know for a fact the one of them works because it has been working flawlessly in my old Dell for the last 2 years. They will let me install the drivers but then they just show up as an unknown PCI device under device manager. I have made sure to download the latest driver from the card manufacturers when I do this and I am still not having any luck. I am running Windows 8.1 and my motherboard is a Gigabyte GA-F2A88XM-D3H. My processor is a AMD A10 7850k if that matters. Somebody Pleeeeeease help me figure this out.
