Ethernet Port is not detected.

So, It's like this: My ethernet port, which is attached to my motherboard, is not detected by my comp. There are two lights, an orange, and a green, normally, they both light up when connected and the green one blinks, and when it's not connected neither lights up. The orange light stays lit up when it's disconnected now. I've tryed reinstalling the driver, changing the cords, and changing the hubs, does anyone have a solution?
Thanks.

 

Did you enable it in the BIOS?

Did you check the Device Manger to see if it Ghosted, http://www.ezlan.net/faq#ghost

Well, it isn't showing up on the device manager, and I can't find it in the BIOS.

 

May very well be a bum ethernet port. PCI ethernet cards are relatively inexpensive now and installing one may say you some grief.
