Solve : Motherboard or software problem??

Answer»

I recently built a computer with Asus A7N8X-X motherboard (onboard LAN )and Sempron 2500 processor, 512 Meg Ram. Windows XP
My problem is that I cannot get the network to work. I should connect to internet via ethernet LAN connection but it does not work.The green LED is lit on the card.
I have tried pinging but it says error yet XP says my network card is good.
I originally had a used Asus motherboard but the network didn't work so I thought it was the card.Is it possible to have 2 faulty cards or is there something wrong with my software.
How can I pin down the fault to hardware or software?
I am connected at the moment via a friends pc from the same network cable that my computer does not work on.
Any ideas?
Do you have the most recent drivers for your card and motherboard installed?

[glb]Flame[/glb]Yes.  The drivers came on a cd with the motherboard.
One thing I forgot to mention is that I tried a seperate network card and that didn't work either.  Also I tried a USB to ethernet adapter which also didn't work.Are there any conflicts...........device manager.........right click on my computer icon//properties....or type msinfo32 or hwinfo in the run box...Suggestions:

1. Disable Windows XP SP2 FIREWALL.
-- Assuming it is installed
2. 'Recover' Network settings
-- Follow the steps written below.

1. Start
2. Configuration
3. Control Panel
4. Network Connections
5. Select your Network connection.
6. Right click -> Recover.
-- Translation may be wrong. COULD be called Repair or something in that manner.I did as you said and clicked on repair, the fault it came up with was unable to renew IP address.
I also clicked run and msinfo32 butI did not know what to look for. There didn't appear to be any conflicts!
What next? have you checked your router/modem/ cable  are they disaplying green leds  check all the connections or even firewalls you may have overlooked [in haste].........what error messages do you get if any>> have you got the nic drivers.........reload them! Quote

Have you tried to manually configure your IP configuration?If I assign an IP address it works. However the IP address is assigned by DHCP and the computer cannot do this for some reason.
After this I removed and then re installed the drivers.  When clicking on Network connections it says enabled and firewalled. I am confused because I uninstalled Norton Internet Security.
Also if I disconnect the ethernet cable the computer detects this and says network cable unplugged. You may need to disable the built-in firewall for Windows.
-- This only applies to Windows XP SP2.

To do so follow these steps:

1. Start
2. Settings
3. Control Panel
4. Security Center
5. Click on 'Windows Firewall'
6. Click on 'Disabled - Not recommended'Could not find security centre, maybe I have the other XP.
I removed the ethernet drivers and re installed them now it says ethernet enabled, but still it does not work.VERY frustrating.
I think I will remove and re install windows XP.

3.  I think I will remove and re install windows XP.

1.  You don't know?  Right-click "My Computer", select "Properties".  What does it SAY under "System"?
2.  Is the ethernet on the motherboard or a seperate plug-in card?
3.  GO to Windows "Device Manager".  Under Network Adapter, select the ethernet card, the properties.  Go to Advanced Tab.  Under "Media Type", what is selected?  Auto Sense?  Reinstalling Windows will not solve this problem.1.  Windows XP Professional version 2002
2.  Ethernet onboard.
3.  Under TCP/IP properties  it says: obtain IP address automatically, obtain dns server address automatically, DHCP enabled.
     I clicked on the Nvidia NFORCE MCP networking adapter configure and it says it is working properly.
     On the network properties it says LAN, enabled and then   AUTOMATIC PRIVATE ADDRESS when this should be assigned by DHCP.
How can I change this The built of Windows XP is of no relevance here. We do need to know wheter you have Service pack 1 or Serivce pack 2 installed.Service Pack 1
