I have A Ryzen 3 1200 mounted on an MSI B350 PC MATE. I have installed the current MSI Flash BIOS that includes support for Windows 7 Pro including USB Drivers. Setup can see the USB Mouse and Keyboard but when Windows begins the install on a virgin WD 10EZEX 1 Tb hard drive the mouse and keyboard will not function.
Did I get the wrong CPU? Is there another Socket AM4 that will work or is there a BIOS fix from AMD that I must also flash?
Thank you in advance for your help with this very frustrating build that I have going o!
