Help, I'm going bonkers

[nightsight]

Alright to start off thanks in advance for any help you can give me. Two days ago I hooked my xbox to my nic card so that it could connect to my wireless network. Bridged the connection and it worked like a charm. Long story short I just replaced my mobo with an abit as8. Wireless network is working great but on my ethernet connection windows is telling me that the "network cable is unplugged". Tried different cables, no go. Tried enabling ICS no go. Checked all settings in the xbox all are good. Something is not letting these two communicate. I know it works cause i had it going before. Have tried both straight and cross cables. Let me know what you guys come up with. Thanks for the help!!!
