I have Ryzen 3 1200 3.1 ghz with Asus b350 plus prime mobo and adata rgb 3000 mhz ram and 1 tb WD HDD. i try to install windows 7 in this system because windows 10 always gave up working properly. When i goes into first screen where the setup starts my keyboard and mouse stop working the lights go off in mouse and in keyboard only numlock light turn up and other keys won't work. Please tell the solution, I can't handle windows 10. I am using usb 2 slot so dont say i used wrong port!!
