LAN Not Working

My On Board LAN Card Not Detecting my internet Line when plugged in it.
LAN card details Listing properly in Device manager and everything seems to be fine, but when i plug the RJ-45 cable, it does not detect any connection and simply show "NETWORK CABLE UNPLUGGED" and a big Red Cross in tray Icon.

Os - Win 7 Ultimate 32
CPU - Intel Dual Core
MOBO - Gigabyte GM31 series
Ram - Kingston 2Gb

I have already tried Drivers Reinstallation but No go.

Please help me resolve my issue.

Other end is My ISP Broad Band Connection, its a direct LAN wire coming to my home. I tested that wire on laptop and its working fine. Not showing up on my desktop.
No its LEDs too not glowing. Seems Like Port is in Deep Sleep mode or may be got corrupted. But If it so then how come its showing perfectly fine in device manager? and also in network connections (control panel) its showing the LAN Connection but stated as disconnected.
Will formatting my PC will help?
M not able to sort out whethr its H/w or OS issue.

It almost sounds like the connection is not making a complete contact with the desktop port.

Well, I would download the stock drivers for it from the manufacturer's website (of the machine or the card, depending on whether you built it or bought it), and then uninstall the device, and replace the current drivers with the ones you've downloaded.

I concur, replace or install the drivers for the lan card (transfer them via USB stick or whatever you have). That failing, since there are not any lights, I would call it a hardware issue, and contact the manufacturer or vendor re: RMA if the warranty or return period is still intact.

As the lan "card" is integrated in the mobo.... that would mean replacing the whole mobo.
Maybe try to get the drivers for the Atheros AR8131/AR8132 first:
GIGABYTE - Motherboard - Socket 775 - GA-G31M-ES2L (rev. 2.3)

Thanks to All to help resolving my issue.
Well I can say even i feel it as Hardware issue since its LEDs Not glowing at all.. as per my knowledge in idle state lan port glows one led and when LAN cable Plugged it glows/blinks other one too.. Mine Both Missing

Moreover i have already downloaded and reinstalled drivers..
Completely removed existing software (also from registry) then re-installed but of no use to me..

After uninstalling drivers it do detects "NEW HARDWARE" and installing fresh drivers again shows it in Device Manager and network connections. Able to ping 127.0.0.1 too.. But only problem LEDs not glowing and not detecting Cable plugged in it... STRANGE!

well, let's not give up yet....This board has some special energy saving options. Are you SURE you have the LAN enabled in BIOS and that you have all powersaving etc off?
