nforce4 NICs dead?

I was playing Descent 3 online with some friends about two weeks ago (as a host) and right after I closed down the game, I noticed that no website would load up in Firefox. After playing with some of the network settings to no effect, I switched the internet connection over to the motherboard's secondary NIC (a Marvell chip) and everything started working fine. The nforce4 NIC is not completely dead, as I can still access my router's settings over it, but I can't get any internet connection off it. I was busy with other things at the time and didn't give much thought to it, as the Marvell NIC was working fine.

Last night, I hosted another game off the same machine and now the nforce4 NIC on my other computer is no longer working. This really makes no sense as the computer wasn't even on at the time (it was physically connected to the network, but that's it). I tried reinstalling the Nvidia network drivers, but that hasn't helped.

I can't imagine what could be going on here. How can a game be messing up NICs like this? Is there any way I can get them to work again?
 
My nForce 4 NIC would just lose its connection randomly. I don't know if it's a known issue, but I hate that motherboard so much, that I will never buy another nVidia chipset system.

I'm loving my Intel chipset now.
 
These DFI NF4 boards have generally worked very well for me until this issue came up. I know the nforce4 NAM and Nvidia firewall are supposed to be dodgy, but I'm not using those at all.

I think I have actually had this happen before a few years ago, on an old A7N8X nforce2 board. I was about to sell it and just assumed it was some software issue, but it was the same type of problem now that I think about it.
 
Possible fix:

1) Run the TCP/IP fix
2) Go to the device manager, locate the nForce NIC, and under the power management tab uncheck all of them.
