If your mouse and keyboard have been operating erratically or the system is not detecting one device or the other, the drivers on both devices may be corrupt. To reset the devices you need to either reinstall or update their drivers. You can accomplish this task by launching the Windows Device Manager utility. The Device Manager displays all the hardware on your computer and allows you to configure their settings, such as by updating a device's driver.
