Sounds a lot like a bad driver, what version of the driver are you using? Did you get it from AMD's site? Do you have the latest chipset drivers installed? Is your A/V software turned off before installing the drivers, and then off again upon the reboot?
we are downloading the latest driver from AMD's site and tried the driver came with the DVD. thou we might not have tried the chipset driver before graphic cards. We will try that tomorrow. also, we don't have anti-virus yet, it's a fresh install. thanks for the reply, keep them coming.
I will update once we attempted chipset driver.
