I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I've encountered this in ATI Radeon video controllers that were (a) failing or (b) overclocked, either memory or shaders.  Given that the system has a Radeon 3600 (very surprising for an I5 system -- the HD3600 is very low end), I'd suspect the video controller and look at replacing it.

If you want to stay in the HD series the 6750 or 6770 are not expensive as used cards and most of them require no additional ATX power lines.  You may have to hunt around a bit to find a card that delivers dual connectors for whatever your monitors accept.  It's easy to find dual DVI cards but the video quality is inferior to HDMI.

There's a good selection of them on fleabay.
