Update your Windows Boot Camp first to 2.1 and then to 2.2. (Download and install from within Windows 7) If that doesn't resolve the problem, you may have to purchase the Snow Leopard upgrade DVD from either Apple or Best Buy = cost $29.99. Use the SL DVD to install drivers for Win 7. (Boot Camp 3.0).
