    need more info are you using a hub or router to connect the 2 or 2 nics and a crossovercable.

    How is this networked? If it is like this:
    Code:
      Modem
        |
    Hub/switch
      /    \
    Comp1 Comp2
    ...it will not work since your ISP most likely only give you one IP. In order to make this work you must have a network looking like this:
    Code:
      Modem
        |
      Router
      /    \
    Comp1 Comp2
    ...or this:
    Code:
    Modem
      |
    Comp1 (with ICS)
      |
    Comp2

    I'm jus gonna run through a few things to get myself familiar with the situation...

    1. you used to link the modem to your pc via usb prior to the new motherboard and since you got the new motherboard, you're connecting it to the PC on the NIC card?

    If so, I would try turning the PC off, and turning the modem off. Wait about 1-2 minutes and turn the modem back on. Wait a moment for the lights to light up correctly (if you link from the set top box (like I do), wait til the top 2 lights are on static) and then turn the PC on.

    Code:
    CABLE    ____  WAN ____ COMP1 _____ LAN _______ LAN _______ COMP2
    MODEM      (PC1 NIC1)  (SERVER)  (PC1 NIC2)   (PC2 NIC1)    (CLIENT)
    
    
    On comp1, is the NIC (linked to the modem) set to get the IP from DHCP? Also, are all the protocols unticked apart from "Internet Protocol (TCP/IP)"?? It's possible when the other NIC is enabled (i.e. when comp2 turns on), ntl are detecting netbios or file sharing on their network and are cutting the line?? Never had the problem myself, but I've always only had TCP/IP enabled on the outside line. I will show screenshots to explain what I mean later on today (should be gettin ready to go out at the min). Check ICS is ticked on the properties of the NIC linked to the cable modem.

    I will refer to the diagram I made above later today - sorry I cant help more right now. Will do later though :)
