After factory resetting my Windows 10 PC it brang me to the Country/Region page to fill out my region and language and what not but since my keyboard and mouse are plugged in like USB's they don't turn on and can't use my keyboard and mouse. The only time they do turn on however is when the PC is booting up but when the screen comes to the Windows 10 logo all the USB ports turn off. I also can't get into the BIOS settings when I press F2 on startup because when I press F2 it just brings me to a black screen with my cursor in the middle and I can't do anything. I've also tried removing and putting back in the CMOS battery inside the PC but that hasn't solved the black screen on the BIOS settings!! Please help me!!
