sabertooth 990fx r2.0 doesn't work on internet - no driver- help


i have just installed windows 7 professional onto my new pc... the mobo is an asus sabertooth 990fx r2.0

the problem is that the mono was second hand and didn't come with the disk, so i have no drivers... specifically the ones relating to internet...

i can't connect with wifi or ethranet

it says to install a driver for my network adaptor.

now, I've tried everything i possibly could think of and still can't resolve this issue...

please someone magically give me a link to download the driver i need
