Graphical Distortions
<div class="IPBDescription">Not just in NS either</div> O.k, I know far too many people use the off-topic forums as a tech-support forum but face it, you guys are GOOD at this stuff <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html//emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /><!--endemo-->
With that in mind, I have a problem.
Yesterday I noticed some graphical distortion while playing Call of Duty. I figured it was just a restart-and-it'll-be-gone thing, so I forgot about it and IRCed for a bit. Today i'm beginning to realise that it's not just call of duty, it happens in all games. While it doesn't exactly make them unplayable, it is very irritating, and it obviously shouldn't be happening.
The screenshot below illustrates my problem, anyone think they can help? Note that i've already tried reinstalling both my current drivers and some old ones, neither of which helped.
Anyone think they can help?
*edit* O.k, i drew red circles around the more obvious areas. It's a lot more noticeable when you're playing, trust me. *edit*

If your having voltage fluctuations they may cause problems like this, check your voltages with some monitoring tool(most motherboards support this now). Fast writes may cause problems like this with some motherboards, it gives a slight performance increase but turning it off may help alot. If you have AGP8x enabled, turning it off may help and won't hurt performance much. A faulty memory module or PSU that is unable to keep up with the load may cause problems like this. Forgetting to plug in the molex or floppy connector to a graphics card that needs extra juice may actually work but be generally unstable and cause memory corruption. upping the AGP voltage in bios(this is a signaling voltage) to 1.6-1.7 V may help.
If you overclock your graphics cards memory too high or overvolt it you will get artifacts like that(may be caused by heat or by simply pushing hardware beyond where it is stable). If your GPU is overclocked you usually get flickering polygons and BSODs.
Rage3d(ATi) or nvnews(nV) forums are much better places to ask than here really, if you don't figure it out.
Better yet, if the fan has stopped and your card has lower power consumption than a radeon 9700 pro or a geforce fx5800 get a zalman zm80(big aluminum sink with a heat pipe). No noise and without a fan it's just an ugly chunk of aluminum, it can't break.

or
try cooling your videocard better, by making sure the air can go along it faster.
(open your pc-box or something/aim a ventilator on the frontside do deliver it a cool breeze, if the surrounding is cooling than the box's intern ofcourse)
