I am getting video card artifacts when I play COD 4, It only happends once in a while but is getting worst. refer to this link...http://www.playtool.com/pages/artifacts/artifacts.html. The guys I play on line with say its my video card and It will have to be replaced. I have a nividia geforce 9800 card, can anyone recommend a card as good or BETTER than this model for online gaming?. Also I have a Hp 22 inch monitor, could this cause problems with my video card?Sounds like overheating to me. TRY downloading and running speedfan http://www.almico.com/speedfan439.exe

Try looking for a GPU temperature after running your game for a while and post it back HEREI already tried speedfan with another advisor, He said temps were ok. If you have a stock or generic PSU I would say it is prob that. Heat will cause as well. I have a consair 620 watt power supply.I recommend the Nvidia Geforce GTX 295. I dont have it but you will get more FPS in games.Check your cables.

I once had some stray pixels hanging AROUND, and it turned out to be a bad cable causing it. Make sure everything is tight, and if you have an extra cable, GIVE that a try.
