What are you using to install windows? And you are aware win 7 is not really compatible with ryzen right? I dont believe any of your usb slots will work on win 7, so if you are trying to install win 7 via usb it wont work at all you need the disc. And even if you did install win 7 with a disc you would not be able to use usb 3.0 at all, you would need a PS2 mouse and keyboard to use the pc ,USB 2.0 might also work partially but that seems to be hit or miss. I would really recommend you get win 10 with a ryzen system.

Can you download win10 and install with Win 7 key?

I assume you already back up your previous HDD?

I never back up xD!

Well i put win 10 cd on drive and voila, its everything is working, even mouse, now installing win 10.
