I'm not exactly sure what you mean, but your graphics card may be overheating. Get a compressed air can and clean out all of the dust around your graphics card fan, as well as the rest of your computer case.

Well it almost sounds as if 1. als bluzman said your GPU is overheating or 2. your GPUs memory is bad.

The 9800 is a pretty old card. Came out in 2003. If it is just overheating you can try to blow the dust out and see if it does help.

To monitor the temperatures, google GPU-Z and download it. Should give you the temp under the Sensors tab. After blowing out the dust try seeing what the temps are on boot and then when playing WoW. If they go above, I would say 80c then its still getting too hot.

Another great tool for testing is ATITools. It can run a test for artifacts. Oh and before I forget, try turning the settings in the monitor down to 16bit. If the lines and blur goes away then that would mean bad video memory.

Hope this helps.

Hi There Again, Any Idea The Ideal Temp It Should Be At? When I'm Running The Net Alone It Says : PCB Temp 47-48.C and the GCU Temp 53.6c, is that too warm?
