I formatted and did a complete clean install of windows 7 ultimate 64 bits. I'm unable to connect to the internet via Ethernet cable. I checked device manager and find that I'm missing the Ethernet controller drivers.
my specs are:
CPU: Intel(R) Pentium(R) dual CPU E2200 @ 2.20Ghz
Memory(Ram) 4.00gbs
Graphics: NVIDIA Geforce 8400 GS
Motherboard:Asrock G41M-VS3
I went to the motherboard manufacturer's website to download the drivers. I downloaded the atharos drivers that were listed in LAN, but now I get the following error when I try to install them ' installer can't find atheros AR81 family Ethernet controller on your system' Please help!!!

This device driver package will install drivers for Intel 82540EP Gigabit Ethernet Controller for the Windows XP operating system.
