Video, Mobo, What went wrong?

I was working on setting up a small lab in my room with some older 486 machines running linux to help me with some of my school work and other things to be automated to make things easier.

The main machine, has a 100mhz Intel and for some reason,I can not get any video to show up on at all.

I have tried 2 or 3 different cards all with the same result.

I believe the mobo is bad. If anybody has any pre-pentium hardware that they dont want, just lemme know.

Is there any chance to savethis mobo?
