I just finished building my first ever PC and about to install Windows 10 through USB, but I notice that when I plug in my keyboard and mouse, neither of them work cuz they should be lighting up. Also, I plugged in the display to the monitor, but it also doesn’t show up. I tried all of the USB ports in the PC, including the front ones, but they don’t work either. Oddly though, all of the fans and LED strip function perfectly fine, so I have no idea what the problem is. Please help me!
