No ethernet driver for is7-v2 in xp/vista/w7

Installs of Xp, vista, and windows 7 have all been unable to find the ethernet controller driver. its onboard LAN but is constantly listed as ethernet controller ( with the lil yellow icon) in device manager.i have the mobo cd and installed all of the stuff out of autorun. later i got desperate and found 3 lan drivers in the cd, but none of them seem to work ( maybe for other models of the board).

pretty annoyed, just want ethernet to work.


on this same board, i tried installing my gigabit PCI card and my MSI wireless PCI card..... neither seem to work, but its possible these are broken.... the motherboard itself is brand new ( never been used )
