Graphics Failure?

[Thawk]

I was playing World of Warcraft and the graphics went nuts and pixels filled the screen and it hung. I rebooted and played more last night OK. This morning it's happened 3x in 3 minutes. The drivers are up todate. What should I look at as the problem? Graphics card? How can I diagnose this problem. Thanks!

I tried replacing the cables and the monitor and it's still happening. It screen starts to lag, pixels go haywire, it hangs and then the system reboots. Now I'm not getting any video.

Check that your card is not overheating ............ Summer is here (for some people anyways)
