video problem w/Abit MB’s

This is the second time, I’ve had to replace an Abit MB because the system I built fires up but doesn’t produce any video upon booting. I have done the Barebone Boot, with no results. After triple checking my connections, I’m wondering “Is it me(?)” or is this a common problem with Abit MB’s? I only purchase this manufacturer’s boards at customers behest! Help!!! Please….. I promise not to recommend another one to anyone if I can get this one out of my shop.
