I've got a very similar situation with the same motherboard but the network adaptor. I was running Win 7 RC for a while, and it was working great, but then it crapped out. I got my Win 7 Home Premium disk and installed it, hoping that would fix the issue, but it hasn't. For some reason, it refuses to work. If anybody has any insight, please share!
Someone in another forum suggested uninstalling it (sw and hw), power up the pc, shut it down, reinstall hw, and fire it up again and let Win 7 either find them for you or install something that works.
