Can't get XP to install my Ethernet driver

[inferlogic]

Hi guys,
I hope someone can help me. i am trying to sort my friends computer out and we had to do a clean install of windows on his hard drive. Its windows XP and for some reason it has not picked up the drivers for the ethernet card sound and video card! I have looked in device manager and can see a yellow exclamation mark and question mark next to them. i have tried to update driver but it won't install and I don't understand why! it keeps stating its recomended to look for an internet connection to download the driver but ofcourse the internet isn't working because we are installing the ethernet driver. How can I install this driver? Any help would be appriciated its a Dell Dimention 5150.

Thanks for any help.

If you don't have the Dell Drivers CD then use another computer to download the correct chipset and networking and any other needed drivers from the Dell web site. Using your friend's Service Tag makes searching on Dell's site far easier. Copy the download(s) via removable media.
