|We don't know if your ethernet card is built into the motherobard or if it's an add-in.|
A couple of suggestions...
1. If you have a modem and internet connection, go to
and click on "Start Detection"
2. On the same page, enter your exact model number.
3. Post back your exact model number and serial number.
4. Bring it over to the house, and I'll do it all for you.
