HP Compaq 6515b buttons aren't responding

[Zilliak]

Well my hp business notebook with vista home premuim isnt responding correctly. The buttons that let me control sound, Internet connectivity, slideshows and information is not responding, it lights up when i press it but it wont do anything. The blue light is constantly on and ihave tried reinstalling the drivers nothing seems to work.
