While on the topic I've got a computer issue too if anyone's willing to help look at it. When playing games or watching video I get these horizontal bands across the screen. They move around a bit but seem to behave a bit differently depending on what I'm doing. In StarCraft II they almost look like the effect you get when videotaping a TV screen where you get these bands across the screen moving vertically. In Just Cause 2 there are still bands but they kind of jiggle in place rather than moving in any direction. So far I've noticed this issue while playing games, watching videos, and occasionally while loading websites.
This is a new PC I just put together and I'm trying to figure out what's causing this problem. I tried switching out my new GeForce 560 Ti for an old 8800 and I still seem to get the issue, but not quite as badly. I'm not really sure what other parts might be the culprit and I don't want to attempt to RMA anything unless I'm pretty certain that part is actually bad.
Here's a picture I tried to grab of the issue while playing Just Cause 2. The effect doesn't show up in screenshots.
