I can't seem to find any results via google or numerous hardware forums about this. Also, I don't know if I'm even using the right word to describe this activity. About every 30-45 minutes my screen will either have a "tear" on the bottom half of the screen or, at the very bottom of the screen next to the taskbar, it will jitter. It almost seems like the monitor is trying to configure it's position whenever this happens. This only happens for a couple of seconds. It's not a huge problem, but I just like to keep my computer up to snuff when I can. I was just curious if anybody would know what causes this. Thanks.
