I purchased an MSI B550M VDH Pro-wifi and an AMD Ryzen 5 5600x. I replaced an AMD FX-6300 and an ASrock AM3+ motherboard the exact make of which I can't remember. After some fiddling, I updated the BIOS to the latest version successfully and was able to boot into windows(7 home premium) on my SSD. However, once in Windows my USB mouse and keyboard cease to work, lights turn off. I don't have a ps/2 keyboard or mouse to use. So, I'm completely unable to use Windows at all. I can't get passed the login screen as I can't type or use the mouse. I have a disc with drivers to install, but I can't do this as I can't actually login or do anything. What do I need to do to get the mouse or keyboard working? Ideally without having to do a fresh install of windows.
EDIT: Having just tried it I can confirm that upon booting into a USB windows installation the mouse and keyboard also stop working. So I can't even perform a new install. The keyboard works in the Safe mode prompt, though. I've tried every USB port and I've tried the keyboard and mouse individually. The USB drive I was running the windows installation off of continued working, the mouse and keyboard did not.
