Hey guys,

Like it sais in the heading: I can't adjust my background light of the screen anymore ; )
Not with the keys on my keyboard (above f5 and f6) or in the energy performance settings.
I updated my NVidia driver a few weeks ago. Than the problem began. After that i tried to deinstall the old driver and deleted all rests of these drivers with some programs i can't remember now (it was an introduction from he internet) :/ and installed the original driver from the asus web page. Unfortunately it didn't solve the problem. I still can't adjust my background light. All of the other funktion keys are working, by the way.
Maybe someone can help me ;)
And sry for my writing style. my english is not that good...

My PC:

Asus G74S
NVIDIA GeForce GTX 560 M
Windows 7
NVIDIA Driver: 320.49

Need more information?
Just ask :P
