Hi guys, Im running a dell sc400 2.8 gigs/ 1.5 gigs of ram with the radeon 9800 256 pro. I am an avid gamer and since I bought the card a few months ago, there has been no problems. However, recently, after a period of having the power on - especially playing games such as unreal/world of warcraft.. little dots start appears/blurring on the screen... they arent so bad that I can't play, however, I can tell the display is flickering back and forth a tiny bit (about 0.5mm jumps).. I have opened up the case while its running but it has not helped. I have uploaded the newest catalyst driver as well.. still a no go. After a while, I see these 3-4 mm squares on the game screen with little dots in them as well.. and the dots/flicker only happens during the games.. not in regular windows display. I have played around with troubleshoting option in which I decelerated the graphics card a bit, however, when I try world of warcraft/unreal 2004 - the cursor just flickers really badly. I tried playing around with every setting on the display options (ati control panel) to no avail.. I just wrote an email to ati 2 days ago but they still have not returned my email.. any ideas what is wrong? Or what I can do to make this better? The computer is shared by me and my gf so it has been played on sometimes for 12 hrs at a time .. but then, shouldnt it be ok for the graphics card? Thanks in advance for all your thoughtful input - anything would help!
