Download Advent laptop drivers for Windows xp.?

I bought an Advent Laptop in UK. Free weeks after I travelled to Gambia. I had been having problems with the preinstalled Windows Vista especially when I want to connect my laptop to my LAN. I decided to format and install Windows Xp. To my amazement, I could not find a manufacturer's website or support website online where I can download necessary drivers for the modem, ethernet, WAN, Video Card and so on. Its really sucks. It seems Advent are the worse PC's I've ever use for support purposes. Can anyone help me locate where I can get the drivers. I have its driver installation CD's, but the drivers are for windows Vista. I need drivers for Windows XP.
