keyboard on my asus a3f does not work properly. actually few keys on it do not work. i think it has happened after i installed windows 7 on my laptop which is xp and vista capable. as most of the drivers did not work on windows 7, i had to uninstall it and go for xp again. and then later i discovered that few keys on my keyboard do not work. so can anyone please help me out to solve this problem.
