I've been given a motherboard from a friend, and I'm using it in a spare computer to run Windows 7. However, it seems it won't connect to the internet through an ethernet cable; it recognizes the connection and gives a green light with an intermittent orange blink, but the OS itself won't seem to acknowledge that there's a connection. I know the cable and the modem and the router works because I can hook it up to my other PC and have it connect just fine. Looking through the BIOS didn't seem to reveal anything, although I'm not quite sure what to look for.
Is there anything that can be done?
