upper and lower filter problem

Hi, follwoing the advice of someone on another forum as to how to get my dvdrw to reappear on my computer i was told to delete the upper and lower filters of the dvd rw. i think however i have delete the filters in the keyboard and mouse by accident as now they are completely unresponsive when i boot up. ive tried using different mouse and keyboard and they didnt work either which leads me to believe it is software and not hardware. i thought i could reinstall windows to solve the problem but i cant move the mouse to tell the disc what to do.

anyone have any ideas as to what to do?

thanks.
