If you have an LCD monitor, try lowering the refresh rate. You may have to lower the resolution, or just adjust the screen size within the same resolution.
I have a set of LCD monitors that are very sensitive to their refresh rate and show these symptoms.

I've been experiencing an annoyance since I built this box. Every once in a while, a few times per day, the video goes blank for a couple of seconds and then comes back as if nothing happened. I'm using the nvidia-supplied drivers and the digital video output. Any clues? TIA&Cheers
