This is extremely weird. I've used this keyboard plenty of times, I see my external hard drive light up, so I tried that usb port, but still nothing. The computer will boot past the bio and go to the login screen, but neither my keyboard or mouse will work. It stopped working while browsing youtube and I restarted my pc. I tried it on my laptop and both my mouse and keyboard work. I'm not sure what's going on because it's not detecting it even in the bios?
