You've not mentioned which motherboard you have but if its an Intel branded motherboard you should have an option in your motherboards BIOS settings (accessible by repeatedly pressing F2 at the initial stages of booting - when displayed on screen by default) to turn off the Ethernet/Network hardware on the board. If you switch this off here and save that setting change as you exit the BIOS setup you won't have the drivers attempting to reinstall when you next boot Windows. Your motherboard manual should tell you moore about how to turn off the network hardware.
Similarly, the motherboard manufacturers should have all the correct drivers for your motherboard available for download on their website. If it's an Intel 'chipset' based motherboard, make sure the chipset drivers are the first to be installed after the OS and all its patches/service packs or there may be problems as a result!
