Hi, you didn't specify what card you have i have ATI 8500DV AIW you have to make sure to download the newest catalyst drivers for your card then when you go to download site to ati DON'T just download the newst drivers cause they wont work on the 8500 DV series go here http://www.ati.com/support/products/...usdrivers.html

there you can finde the older drivers download the 7.7.0.1. make sure to delete the one you have.

Hope it works.
