Can't Connect To Internet

[Sufc811]

Hi,

A good while ago i used a reload disc on my pc and it automatically came with windows xp home eddition on it. So i had my pc back up and running after loads of problems and used my System & Driver CD i had. I Re-Installed the drivers on there. My sound is working so is my disc drivers and everything elce. Just two things, my pc wont dettect when i connect a USB or it wont connect to the internet. My main problem is the internet. I am using wired internet and i have a BT-HomeHub. It works fine on the laptop on wireless i am using now and fine wired to my Xbox. Just my pc wont detect the internet. Can Modem Drivers have anything to do with this? Or is it something elce? Also the only connection i have is the 1394 connection but the Address Type, IP Address, Subnet Mask and all of them says <Unavalible>. Help would be my appreciated as i have been living with this problem with a long time now. Much thanks and if you need anymore info i will answer back quick as possible.

Many Thanks,
