Getting some green artifacts on my screen

[issues]

My card is a Geforce 6600 GT OC and in the last couple months I've noticed sometimes I'll get some flashing green artifacts on my screen. I'm not sure how or why they appear so I'm asking this to see if anyone here may know. I was thinking maybe its too much stress putting on the card or just running to long. I don't really leave my computer on to long, maybe 12 hours max. I do have a lifetime warranty on this card so if it is dying I might just get another or new one altogether.

Green artifacting is a sign of too much overclocking. It happens to me when I try to overclock my GPU core by too much.

Hrmm, well this card was overclocked by the company that sold me it (BFG? I think). So does that mean the GPU is having to much stress put on it by certain games or maybe just running to long?

I get green artifacting whilst playing Oblivion and my video card is a X1900XT 512Mb with a third party cooler from Arctic and it's not overclocked (unless the ATI tools is set to automatic overclocking, which I ought to check!). However I don't get this problem in any other game.

Is you artifacting a sort of grainy artifacting or is it great big chunks of the picture that is corrupting?

I'm not quite sure how to describe it. It jumps around the screen in little bright green blocks, sometimes very small to about medium sized. I've had it happen to me on Dungeon Siege 2, Company of Heroes demo, and now M2TW. It hasn't happened with WoW which I play quite frequently so I'm baffled about that. I do think they stick to separate objects like say a siege tower or a person etc. Truthfully I don't pay attention because normally I'll turn off the computer and it won't come back for a while.
