Why WindowsXP does not accept the correct NIC driver?

I have a serious problem with my PC.
I had to format my disk and reinstall Windows XP (with SP2), but I can not
get to in web because Windows thinks that my network card is of Asound, but
its of Realtek.

I tried doing update driver using the Realtek RTL8139/810X Family PCI Fast
Ethernet Card driver on the device manager.
I tried uninstalling the driver, and then letting Windows find it again.
I tried downloading new driver from the Internet (using another PC).

But came out Asound. Windows simply does not let me change the driver.

I logged in with Administrator account.

I talked with the my ISP service provider, and they also found that the
trouble is with my NIC.

How can I force Windows use the driver that has on a disk, and not the
built-in Asound?

Ok, it's working now.

After boot to safe mode and removing the driver, and the restarting again
and manually updating the driver to my specific INF file which I have with
the NIC itself. And it's working.

Thank you for you kind help
