Yes I have the 9500 pro and it's just the same. ATI's support is pitiful and there products are simply arse. I would never touch another product with that logo on the box EVER.
I suppose you have been through the useless help pages on the site?
You can email them, they will take an age to reply and then tell you that "in our experience these problems are usually a configuration problem" REALLY I am surprised. They give you a ref number to use if you need to reply for further help, when you do this they simply ignore you.
My advice, sell it and get a decent card from a decent manafacturer who cares about their customers.
