Ethernet Controller not working on new mobo

I posted this in the drivers section, but it could be a hardware problem, so i'll post it here, too.

Hey all.
I've read the other threads for this, but they seem to be for different pieces of hardware.

So I upgraded to a new Intel Mobo - an Intel D865GBF - and somehow, I overlooked the fact that it didn't have an onboard LAN or Ethernet controller. So, no biggy, I just bought a cheap Realtek 8139D Ethernet Controller card.
I turned on the PC, everything was detected except for the 8139D Ethernet Controller card. I search for all sorts of drivers - i've probably searched and installed about 50 drivers; all from different sites...still no luck.

I tested the card on this PC and it works fine. Now i'm looking into the actual configurations and settings of the new PC and don't find anything out of the ordinary.

So yeah...any help?

Note - I thought it was the BIOS that may have been messing with me, so I decided to upgrade it to the most up-to-date and still, nothing.

 

I take it you have the latest motherboard chipset driver ??? have you tried in other PCI slots. Also what OS are you using as the specs I have just read for the card does not include Vista.

 

Hi, sorry for the late reply.
As of now, there's still no luck. I decided to just buy another mobo with an onboard LAN but I would still like to get the other one working. It's currently just sitting in a closet as of now.

I am running on Windows XP on all my PCs. I tried all the PCI slots, no luck.
As far as the specs, i'm running

Intel P4 2.79 ghz, 768 ram.
