i was using my pc and my keyboard suddenly stopped working. i couldn’t type anything but it would still light up. i restarted my pc but then both my mouse and keyboard wouldn’t work and i couldn’t get pass the lock screen. i bought a cheaper mouse to see if it would work and it still wouldn’t. i tried all other ports, configuring settings on BIOS, and startup repair (it did not work because idk the administrator password). i really don’t understand what went wrong and what else to do, please help! :))
One thing you can try is booting windows in safe mode with networking, press f4 when the computer is booting up. If it works, try redownloading drivers either with windows update or through the hardware panel in the control panel
