It's extremely unlikely that either the monitor or motherboard are causing
the problem; it's almost certainly the video board, despite the fact that 
a second card does the same thing.  I'd guess that the design is a bit flaky
at the speed needed for 1024x768 non-interlaced, and it may take quite a few
boards to find one that works.
