Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Just install the ethernet drivers, and whatever else is absolutely necessary to get it up and onto nVidia.com. Once you're there, you can get the latest version of the driver suite, and install that at your leisure. After downlading the nForce driver-lith, remove the old drivers with Add/Remove Programs, and install the new drivers for everything, even if you later disable some of the devices. WinXP tends to piss and moan about onboard components that aren't set up with some kind of driver, and it'll just cause you headaches in the long run.
