So I recently reformatted an old machine, and I seemed to have forgotten the proper drivers for my mobo. So I check and it's an intel D850EMV2. According to the intel site, the proper drivers are these. However, they don't install properly on my machine. But the thing is now when I reflect back on it, I clearly remember using the Realtek AC'97. So I go back and try those and the installation goes fine but upon reboot it still doesn't recognize the hardware and shows up as a (?) Multimedia controller in my device manager. Where do I go from here?
