Motherboard Network Driver Help

Hey guys I need your help. I re-isntalled windows on my PC recently but i cant seem to find my bloody motherboard drivers CD.

Ive managed to get my Realtek sound working (after some trial and error with drivers) but I cant seem to get my network card working because there are many drivers to choose from and I dont know which one to go for. When I try to use the NTL broadband 'activate the internet' CD, it says that it cant make a connection to my Network Card. Obviously a driver problem?

I have an intel P35 PCI/e motherboard (made by gigabyte)

Chipset: Intel Gee/G31 Express Chipset
Memory Controller: Intel 82G33/G31 Memory Controller Hub
I/O Controller: Intel 82801IR Intel I/O Controller Hub (ICH9R)

Have a look at this: http://driverzone.com/manufacturer.php?man=Realtek+Semiconductor+Corp&cat=6

Also on the realtek website.. http://www.realtek.com.tw/downloads/

Theres so many and I need to get this sorted before I get to Uni (saturday)...

By the way, if I ring NTL/Virgin helpline (the company im trying to connect to the internet to) do you reckon they will know what drivers I should get?

ALSO... In my Device manager, there is an exclamation mark (!) under OTHER DEVICES -> SM BUS CONTROLLER

where can i get the frivers for this from?
