Strange artifacts.. what may be the cause?

Recently I have been occasionally seeing strange artifacts while on the desktop. They appear as either a straight line or a dot-matrix style cluster of red pixels. Look closely and they appear to be flickering. I had experienced the artifacts in the past, possibly with a different card of the same model, though I am not sure if it was this card, or the one I originally bought and had to get replaced (got fried during a power outage). After being free of the artifacts for a while (months definitely), they're back.

I have had success in temporarily getting rid of them by turning off my monitor for about ten seconds. This usually works. Recently I had attempted unlocking the extra pixel and vertex pipelines. After the unlock, I was getting different artifacts in games, so I disabled the pipelines again. I had also installed Folding@Home, but had some stability issues with it and haven't been running it. Alas the artifacts remain however. I'm having a hard time figuring out if this is caused by the monitor, cables, video card or something else. If anyone can help me to shed some light on the situation, it would be most appreciated. Thanks! :D
 
just by the fact that they are "cured" by turning off the monitor leads me to believe that the monitor, or something physical near/plugged into the monitor is giving you problems.

I am assuming you are on a LCD, so that sort of artifacting leads me to think its a bad/broken pin in your dvi/vga cable.

I'd suggest getting another monitor or cable and see if the problem persists.
 
I had thought they were the monitor. I'll see what I can do in terms of finding another cable to try it out. I should have one around here somewhere... Much thanks for the advice!
