I have the Geforce 7600GT, it has been running great for about 2 years now. Recently when playing World of warcraft I have been having times where the screen freezes for 10-15 seconds then comes back. Other times where I get triangle shapes around the screen. and I have in the last week had the computer restart itself while the screen was frozen. Is the video card dying? I have current anti virus and spyware. My computer is clean. What could this be. I have since reduced the video quality settings on wow from high to medium.
