Ethernet driver for EPoX EP-8KDA3J

I have this exact same mobotherboard. Did you install the chipset drivers? You need to download and install the nforce3 chipset driver. It includes the nic driver and all other things you're probably missing besides video and sound.

I should tell you that my onboard NIC had problems on this motherboard. Sometimes it would lose connection, sometimes it would make my pc take 5 minutes to boot up when the cable was plugged in or just crash my computer.

I just use a PCI nic now. But you'll want to install that driver anyway. If you use a PCI nic, then go to Control Panel, Network Connections and right click the nforce nic and click Disable.

Try updating the BIOS with the latest update that you can download here:

ignore the button that says to download the driver update pro, and scroll down a little further. You will have to enter a code to get the latest, then get back to me if it still doesn't work.
