Well ... frankly, simply because you know the vidcards and monitor are good may not be the whole story. By way of example: I have a Soyo board sitting in the other room with a 233MMX - I think that's a Socket 7 ... anyway it has a good vidcard in it also, but the motherboard is a poor design or bad run or something because vidcards do not seat in the AGP slot properly. Everytime I use the computer, I must power it up then hit Reset. Otherwise the test monitor I use simply flashes "No Video Signal." I realize it sounds silly, but this is for real. Long story longer: your vidcard (or something else) may not be seating properly on
that board.
Good luck.
