Thank you for the very detailed and quite informative response to my
original post. I am still struggling with this situation and have tried a
different PCI video card to no avail. I searched my 'spare parts' locker in
the hopes of finding an old ISA video card but no luck. Your suggestion of a
different monitor gives me one more thing to try. Do you think that an AGP
card would have any chance at success? I have been considering going in that
direction.

The one thing that has me puzzled is that the current hardware had been
working fine for the past 6 months. That's why I am at a loss to explain why
simply moving the video card could have started this chain of events. I did
suspect that my video card was not properly seated but have checked and
rechecked that several times.

Thanks for your response. This list has proved invaluable in
solving/preventing problems with the systems that I have built over the past
few years. I am a real novice learning as I go but it is sure fun.
