Patterns on screen...graphics card malfunctioning?

I have recently begun to see various patterns appearing on the screen after the pc has been on a while, eventually getting worse until the video signal from the pc is so poor that the screen turns off (ala power saving mode). I know that the monitor is not the problem - could it be the graphics card overheating or some other problem?

I've uploaded some screenshots that illustrate the problem a little (the patterns here are when it's not that bad):

Could be overheating....take the side off the pc and check to see if the fan on the graphics card/processor and any other fans are working.If there is a lot of dust in the case then you may just be in need of a good clean up.
