Do you have SP1 installed now?
Try reinstalling whichever WHQL driver is the most stable for you, but do it this way and see if it helps.
I am going to give you some links that will help you get a good clean install and not have any drivers you don't need that will conflict with other drivers. Download a WHQL driver from https://www.sevenforums.com/graphic-c...ndows-7-a.html . Once you have them downloaded, uninstall you current driver from control panel. next clean up any left over drivers from following this tutorial Drivers - Clean Left over Files after Uninstalling and select only ATI Display Drivers. After you have done that and rebooted, install the new driver, only select custom install and install only what you have to. Very few people need most of what they include. You do not need the audio/HDMI drivers as you already have that in your Motherboard drivers. Unless there is some reason you need them, the only thing you really need is the Display Driver.
With a graphics card there is very little involved. The drivers, the card, the Motherboard and the PSU. If you can find no drivers that work, it pretty much means it is not drivers. If you can borrow another good, working card and run it OK, that means it is not the Motherboard. If you try your card in another machine with an ample PSU and it has the same problem, it will pretty much say it is the card.
Also, I didn't say it, but if you are overclocking, set everything back to default levels. Also, remember your card, from what I can find, can spike up to pulling well over 300 Watts.
