A friend of mine recently purchased a Diamond S220  video card.  It
works great.  But, he says once in a while the video simply goes black
and the only way to get it back is to reboot (Win95).  It never did this
with the old video card.  He's a real novice and did this himself.  I
told him I suspect the card may not be seated.  And to shut the system
down, remove the card, and reinsert.   Or, there is a loose wire in the
cable.

Did I advise him correctly?  What else could it be?
