Graphical glitches on individual windows?

[sackboy]

I'm getting these really annoying (and game breaking until I exit the game and then come back in) graphical glitches on either one or two of my windows at a time. As you can see in the screenshot, my main window and one of the alts is getting these weird flashy lines all over the screen. It somestimes bugs out like that, or sometimes will just flash the screen / UI on and off a bunch of times. This mainly happens during populated areas (and rarely happens in instances and the like).

Anyone know what causes this? I'm running all 3 on one computer (quad core 2.9ghz, GTX 460 1GB, 4 Gigs of ram that will be 8 gigs on monday) so I'm pretty sure I can run it on my rig. I also have tweaked the graphic settings to make it pretty darn low on all three thinking that would fix it but it still occurs.

I was having that problem 5 boxing. After tring a few times, the only thing that I found that fixed it (for me) was adding a 5th fan and having it blow directly across the video card. I had 4 fans running at that time in my system so I never thought it could be my video card runing hot. My video card has an on board fan so it was the last thing I looked at. Since I added that fan I have 5 boxed with my main monitor set on ultra and my second monitor, the 4 alts, set on good. No problems since.

I was also thinking Temps.

This looks like artifacts brought on by overheating hardware. If you have your card over clocked, take it down a notch. Add more cooling and most importantly BLOW OUT DUST from fans / sinks. Dust is a computer killer.

You could also fix the problem the way I did... submerge your entire computer in oil... lol I want to see a liquid cooler crank out this kind of performance / reliability.
