I guess it was around March I started noticing that while watching flash based videos most of the deep black colored objects would have this bright colored pattern go across them. I would restart and it goes away. It started happenning more frequently but only on flash videos. Well, yesterday it appeared in-game for the first time. It's only in areas where it's dark black. I'll post a picture when I get home to show you exactly what I mean. But I was wondering if any of you have any idea what could be causing this. Over heating? Update drivers? The card was just installed last November. I even cleaned any dust out of it to see if that was causing it. I have the Antec 900 case like most of you and I didn't think cooling would be a problem. Any help is appreciated. Thanks.

Can't really say without seeing a picture of it first, but it sounds somewhat like your memory is bad on the graphics card. The alternative would be bad drivers.

This is an example. I think it may be an overheating problem because when I restart it goes away and it never really occurred until it got a bit warmer out. Could be dust too, but I cleaned it all out already.

wtf? It doesn't show up when I post the image? Well just imagine that black area covered with yellow streaks.

I just lost a graphics card to bad memory that freaked out, I tried to take a SS to send Fox and it sent it just fine. You might have some memory going bad

Two of my vid card actually did that (and it burned some time later) and the same, screenshot did look ok.

First time: Updating the driver did work but part time.

Second time: Vid card burned in the week after it started.
