problem with drivers

So now I have a notebook ASUS K70IO with the sys win. 7.which wasn't uploaded from the outset(i had vista) and as soon as I installed it shortcuts as volume control, webcam, etc (the standard as in all the notebooks F9,F10 etc)do not run (works well in vista). My guess is that they are the drivers for this, but I have no idea how to call them that's why I cannot find them... please help<3
