I bought a new ryzen 3700x to switch out my 2600x. My motherboard supports it and I downloaded the bios flash into my usb stick after formatting. The files show up but the bios file doesnt. I've extracted and formatted and tried a million things but nothing seems to work. I'm trying to do it with my old cpu in so I can still use the pc. I need another way other than this. Msi b450 gaming plus, ryzen 3600x, usb is 32gb some brand
