If there are no better suggestions then here are some things you might 
try.  These are all based on my underlying assumption that it's somehow 
the graphics card/driver:

    1) Check BIOS settings, just in case.  If there are any graphics 
related try changing them.

    2) Try the nvidia forums and see if there's anything there about 
screen corruption.  I'd try the Linux as well as FreeBSD and maybe 
anything about your specific board.

    3) You could try downgrading each port in turn and seeing if the 
problem goes away.  sysutils/portdowngrade can do that for you.  Time 
consuming, frustrating, and possibly fruitless.

    4) If you have another graphics card to hand, see if that has the 
same problem.
