Sounds like your graphics card is dying. Mine was one of many which did that (I believe the Nvidia GeForce 8600 model was particularly prone to failure. I was still under the 1-year warranty, but also have AppleCare. I hope you do too, as this requires a replacement of the entire mother board. Apple fixed mine and had it back within a few days.
