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

First of all thanks.

Dear I can not find Yellow exclamation on device manger.

Now i downloaded graphic driver from here

Now driver some times work fine some time does not work.

For example some time when i press Fn + ( Left or Right ) it changes brightness but after a while it does not work.

Any fix?

about the touchpad, did you installed the drivers from Acer website?

if yes, which one?
