Hi all,
i recently upgraded my computer.
Following is my configuration:

Motherboad : GigaByte GA-945GCM-S2L/S2C
OS Name : Microsoft Windows XP Professional
Version : 5.1.2600 Service Pack 2 Build 2600
Motherboard Model : 945GCM-S2C (Gigabyte Technology Co., Ltd.)
CPU : Dual Core 3.0 Ghz, Intel® 82945G Express Chipset Family
Memory : 1 Gb DDR 2
HDD : 160 Gb SATA Drive
Network Adaptor Type : Onboard
Network Adaptor Model : Realtek RTL8139/810x Family Fast Ethernet NIC


I assembled all the components myself. I installed all the drivers from the drivers CD that came with the GigaByte motherboard, except the Network adapter everything else seems to be fine. I connected my External DSL Modem to my computer and there was no response from the computer. Link Light Status : Both the lights are off when the system has completely booted up, but while rebooting the system i can see the link lights coming up and going off.

I went to the computer shop and got a new motherboard instead of this one( exact configuration)

I reinstalled everything, even the OS. but still i am not able to use the onboard LAN it gives teh same messae "LAN Unplugged" even though its connected.
I checked the DSL Modem, its working fine on my old computer but not on the present one. I replaced the LAN cable as well. No go. Please help. I am now using the USB connection option of the DSL Modem which is relatively slow. Please Help!


My IRQ Setting :

Resource Device Status
IRQ 0 System timer OK
IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard OK
IRQ 4 Communications Port (COM1) OK
IRQ 6 Standard floppy disk controller OK

Hello,
Did you install the driver for your NIC?
Your motherboard should have had a disc with the drivers on it.
If not you can download the driver for your NIC Here

yes sir i did... i tried installing them manually and also by the Xpress install option (automatically all the drivers of the respective hardwares). but no go. I also tried disabling the onboard NIC and i installed a PCI card. but i am not able to load the drivers for the same. whenever i try its not locating the drivers for it and has a "?" mark :)

Please tell me the make and model number of your pci NIC.
Did you go to the link that I provided and download the driver for your on board NIC?
If so, double click and follow the on screen instructions.
You will have to reboot the computer after installing the driver.

I didnt try that.... as there is no "!" or "?" mark next to the onboard Network Adaptor.
my PCI card is Realtek RTL 8139D and when i search for drivers/locate it, the system skips t n says there is no driver available! :)

The driver from the link that I posted is a zipped file.
You have to open the file to unzip it.
Save the file to your desktop when you download it (go ahead and download it again) or copy it to your desktop from flash drive or disc.
Then open the file.
If you used a valid copy of XP to install then there should not be a problem.

Assuming that you have installed the driver for the pci NIC,
Try going in to device manager;
  • Right click the pci NIC.
  • Select uninstall.
  • Reboot the computer.
When you reboot does the computer find the new hardware?

I've got exactly the same problem with the same board. Don't have a PCI nic nearby now, but really looks as if the board is an out-of-box failure. No matter what you do, it says network cable unplugged.

Ever managed to solve this problem?
