Keyboard and mouse stop working in windows

I have a Gateway M520 laptop . The cd player stopped working. Mircosoft web site suggested to make changes to reg. "upperfilter" and "lowerfilter' I did what it said . I had to reboot. Now my keyboard and mouse will not work . The only thing I can do is use arrow buttons to start safe mode.But nothing more. The CD player still does not work. So I can not use it to reboot
