My WinXP machine freezes 1 minute after booting up and logging in. The motherboard has a built in Ethernet port and sound, separate video card.
I booted into safe mode with networking but there is no network available
Looked at Device Manager list and no network card exists.
Disabled network in BIOS (MAC option) boots into regular mode and does not lock up.
I then installed a network card, booted into regular mode but it locks up just like before.
I then booted into safe mode with networking and the network card and internet connection works.
Is this a bad motherboard?
this could be corrupted drivers, go into the control panel/ system / hardware / device manager/ select the "network adapters" device and uninstall it, in your case you may find the original onboard network device and the additional network card you have added uninstall both. and then SWITCH the pc off.
while off remove the additional card, reboot and go into the BIOS, and activate the onboard network device, SAVE settings and reboot, then after windows starts back if it asks for drivers for new device found, install the drivers for the motherboard, that should fix it all.
if the onboard network device is not working you must disable it in the BIOS. then fit the network card into the PCI slot and reboot, then when widows is up and running it will find the device and ask for drivers, then install the drivers.
a reboot will be required likely after the new drivers are installed, then the main network settings can happen during the reboot, then test for network/internet connections

I cannot uninstall the onboard network adapter because the computer freezes before I can get it uninstalled.
The onboard network adapter does not show up in the Device manager in safe mode even when it is enabled in BIOS. So I uninstalled in safe mode the extra network card, disabled the MAC in BIOS, then rebooted into normal mode and it detected the additional network adapter, but it locked up again.
I also tried installing the latest Nvidia LAN driver but that did not fix things.
Right now I am getting by with a USB Ethernet adapter.
One thing you can try is re-installing the MBoard drivers...what options for the onboard NIC are listed in the BIOS ? ?Can you tell us a little more info please?

what make/model of computer?
what make model of motherboard?
cpu ?
ram?
what size is the power supply rated at? in watts

as long as the onboard NIC is active in the BIOS, any additional NIC will have problems, it has to be disabled in the BIOS.
what make is it anyway?

is there any chance it is set at 1000Mbps ? auto negotiable is better.


If after trying what Patio suggests and if that doesn't work, get another NIC. They're cheap enough. Remember to disable the onboard NIC
