I have a problem with the mobo not booting to post. I have tried 3 different video cards, and 2 different cases. Fans and hdrive will spin. I know the ram is good, have tested it in another pc. Have pulled mobo out of case and tried it aswell. This is second mobo/cpu combo, sent first one back for rma they found nothing wrong with it. I'm al a loss have been fighting with this for some time now. Even with just video,ram, and cpu it will not post.Someone must have an idea. Have reseated everything multi times. Everything is new . Full tower atx w/300w supply, Abit VT6X4 w/P3 733 Coppermine, 266mb pc 133 dim. all new. I'm at the end of my rope
