I have an Acer Aspire V5-471 and downgraded it from Windows 8 to Windows 7 64bit

 

Got all my drivers from this site to install for my new OS and all seems to be working fine except the fn key adjustment for the display brightness of my monitor. My fn key for audio adjustment is working fine but not for the brightness. 

 

How can I fix this? please help
