I install the chipset again now and the management engine interface but nothings happen.. Still no display in pcie x16 (blue) and x8 (white).. I never touch those slot.. I just insert the vcard.. Specially the white slot.. Do you think its broken.

If the card works on another PC, and not on this one... it sounds like the board is defective.

Is that the problem?? How about the bios setting?? I use default.. But nothing happened.. How could it be defective?? In what reason? I dont touch it.. Specially the white slot.. I use only the blue slot..

It sounds like that is the problem. The black slot is only x4 lanes. You don't want to use that. If it were mine, I'd RMA the board back to the retailer. If too late, I'd get an RMA from the manufacturer and send it in.
