Ok, so I got my new computer with this graphic card 4 days ago. I'm pretty sure, that there was no flickering at the beginning, but now ...
When I chat on MSN, watch movies or simply do nothing, there is no flickering at all. But, when I browse on the internet, play games or try switch between programs or windows, whole screen starts to flicker and it happens every 2-3 seconds.
I can't really describe it, but it looks like 'quick screen refresh' or something like that. It happens in a second.
At first I thought, that it was monitor problem (4 days old LG L227WTP-PF), but I tried everything and now I think, that maybe some graphic card settings are causing the problem.
What can I do? This flickering is really disturbing, when I play games. Maybe I could get used to it, if it occured only during internet browsing, but not now.
Intel Core 2 Duo E8500
Power Color ATI Radeon HD4870, 1GB
Corsair 4GB 1066MHz RAM
ASUS P5Q Pro Motherboard
640 GB Blue Caviar, WD
PCPower Silencer 610W
I completely uninstalled and reinstalled it. (Catalyst Suite 8.12 is latest version, right?) Somehow it seems, that driver itself is cause for flickering. In time between uninstall and reinstall there was no flickering at all.
I know, it sounds impossible, but this is, how it is ... When I didn't have drivers installed, there was no flickering. -.-
*sigh* It didn't work 100%. When I play games, everything still flickers a lot and I experience some other problems as well. Should I downclock graphic card?
(actually, I didn't know till' yesterday, that my card is actually overclocked version already ... -.-)
Now I know, that I won't listen to my father next time, he says "PowerColor or Sapphire, it doesn't make any difference". (actually it was Sapphire card, that was supposed be in my new computer, but ... I actually don't know, why I got PowerColor then. I realized it, when I started to read list of components on the way home from electronic shop. -.- But my father knew about this change for at least a day already. -.-)
That's true, you can set it at the normal clocks of the HD4870, might work.

I have almost the exact system you do and im having the smae problem. Too the point that it even flickers on startup and shutdown. Sometimes it just goes compleatly black for about 30secs. Comps only 2 days old and ive tried everything i know to sort it. If someone can help it would be much appreciated.
Screw fixing the problme yourself, if you bought it only a few days ago and it doesnt work then go get it returned. These people charge enough of a premium to do such basic tasks for you so dont feel bad about getting a good service in return. Certainly dont underclock it if you have paid for an overclocked version!
