Weird graphical glitch

[Pressure]

Recently I've been having this weird graphical glitch in all my games. I tried reformatting but that didn't help any. I have all the latest drivers and stuff so that's not the problem. My system specs are:

Pentium IV "C" - 3.0 GHZ
1024mb DDR400 PC3200 RAM - Some Generic Brand
Saphire Radeon 9800 Pro 128mb 256bit
Western Digital 80gb HDD with 8mb buffer
ABIT IC7-G Mobo
Windows XP

What happens is that the screen gets bombarded with all these weird things. It's really hard to describe. Anyways they come up about 10-30 times per second making it hard to see. The first screen is a normal shot the rest are with the glitches. Here are the screens:

The problem is pretty clear, those things are called artifacts. They are caused when the vid card is overheating. Solution, clean your case (remove dust) especially in the fans, add more fans, increase the speed of the fans, let your case open, change the fan on your vid card for a better one, change your vid card. Where do you live? If it's getting real hot in summer then you'll have to do something to cool your case/cpu/gpu.

Just to let ya know, I get those as well but only when I'm watching a vid clip while playing WoW. You don't by chance have any video or flash from a website running when this happens do you?

Otherwise it would be artifacts causes generally by heat. If it does it all the time, it could be bad memory or other issues too but that isn't too common.

I cleaned my case when I reformatted.

I'm running Windows Media Player in the background but now it's starting to do it in CS:S and it's never done that before when I listened to music. I'll try turnin everything off and see what the results are.

Are you overclocking? Maybe your video card is already damaged. Maybe even a driver problem?
