Integrated graphics upgrade problem

[detector]

I just purchased a lenovo h405 (xII 650)  few days ago, which apparently comes with

ati 3000 integrated gpu. 

Upgrading to the latest drivers for the gpu causes a degradation in video performace

Not to mention ati has a myriad of errors related to its catalyst installation process.

Has anyone encountered this problem and what exactly are the correct drivers for this model

LENOVO Lenovo) Video Adapter AMD 760G

hey detector,

welcome to the forums

could you try uninstalling the current graphic driver that you're using, let windows install its generic drivers and see if that makes any difference.

at the same time, drop over to >> http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=336617

and update all the drivers and see if it makes any difference.

i can't even get these drivers to download..

The ati site (auto scan) says i need the ATI Radeon graphics 3000 drivers

(Installation says package failure)

windows says i need the 760g graphic drivers

This is ridiculously confusing

Thanks for the help anyhow.
