I Installed Windows 8.1 PRO on acer aspire v5-571-6471.

But Now I am faceing a few problems given below.

1. I can not install Windows 8.1 64 bit graphic drivers provided on official acer website. it says "system does not meet the minimum requirements for installing the software".

2. I can not change brightness by Fn+ ( Down Or Up ) though it shows on screen sliders sliding down and up but brightness does not change.

3. I can not Use Touchpad Gestures.

I bought this used laptop week ago, it was having windows 7 installed.

any help will be appriciated.

Thanks
