Ok here is a Weird one. I have Windows XP. All of the sudden my keyboard is not working anymore (Not USB). What happens is the lights come on during boot and I am able to press the Numb Lock on and off. I am able to press F8 during boot and it does work. But as soon as the Windows XP flash screen appears the lights flash and then go off and then I am not able to press any keys on the keyboard nothing works. . I have tried re-install drivers form device manager and also three different keyboards.
