Try the master Driver from http://ATI.com.
They have the most current drivers that all the Video Cards run off of. You should see the Driver Download Menu on the homepage. Just find your model and download the drivers. Hope that works. If not, you may want to reset your BIOS Memory. Look in your motherboard manual for how to Reset The CMOS Jumper Pins.
Also, how do you have your 9GB of RAM set in there? How many lanes do you have? The only reason I ask is becasue that is an odd amount to have, and I don't see how you have them paired right, unless you have 3 single lanes of 3GB sticks. As far as I know, they don't make 3GB sticks of RAM.
