Ethernet controller drivers missing

Hello,
I recently reinstalled windows on my computer due to a series of crashed and the win32 virus, i used my factiry CD.
I use the Windows XP Media Center Edition, my machine is an eMachines W3507
At the begginning, i had the all famous NTLDR is compressed message, so i could't go anywhere from there, so i switched my hard drive from class selective to slave, and only then was i able to reinstall windows.
It was all going well until i tried to go on the internet, i said that my ethernet controller drivers were missing, and so were the drivers for my pci modem, so after 2 weeks of downloading and installing the incorrect drivers for my ethernet controller, i gave up and now i find myself typing this message.
I have lost all hope on the assholes at eMachines customer service, because they just tell me to call some guy in India, and he tells me to give him my credit card number, because i never put my coomputer on a waranty.

Does anybody know a website where i can download these drivers, or someone who can help me?
Any help would be gratefully received
thanks in advance
Alex
