I've tried a couple more things: Uninstalled Nvidia Geforce Experience (apparently related to the nvbackend file) - No difference Reinstalled Nvidia Geforce Experience, but this time opted not to optimise any games' video settings - No difference Recreated the firewall rule for Ghosts to have 4 separate rules (TCP and UDP, in and out) - No difference Set up a DMZ in my router with my PC's static IP (I use a TP-Link WDR4900) - No difference This is INFURIATING!!! Seeing as I also have firewall enabled in my router, what are the risks associated with just running the game with the ESET firewall disabled??

Hi Marcos, Thanks for the reply! I'm not sure what you mean by creating bi-directional rules? Do you mean creating 4 rules (i.e. TCP in/out and UDP in/out)? Do these games use any other protocols (perhaps that's a stupid question...)? In terms of logging the issues, I have set any rule related to Steam or Nvidia or any COD game to log its actions. I then ran all three games (MW2, MW3 and Ghosts) in multiplayer mode. This ran from the time of 23:41 until the PC crashed again with Ghosts (the first two ran perfectly). The PC was booted back up by around 23:48. I tried to include the log file, but it's too long to post here, and when I shortened it, it just posted as gibberish... Is there a clever way to share the xls here? It was interesting that the log file showed communication allowed for this file: C:\Program Files (x86)\NVIDIA Corporation\Update Core\NvBackend.exe (TCP) a couple of seconds after launching Ghosts. Not sure if that plays a role?

Hi, after an immense amount of troubleshooting, I have finally isolated the issue of COD Ghosts multiplayer consistently completely crashing every time it starts. It crashes so badly that I have to restart my PC from the ctrl-alt-del screen. The crashing started on 12 Dec after the latest patch was applied on the Steam platform. It appears to be related to my ESET Smart Security firewall. Whenever I disable the firewall completely, the game runs. But it used to work fine before the patch! I have: Upgraded to Smart Security 7 (didn't make a difference) Recreated the firewall rule for iw6mp64_ship.exe (didn't make a differerence) Tried to run the firewall in automatic, automatic with filtering, interactive and learning modes (didn't make a difference) Are other users experiencing the same, and maybe have a solution? I cannot see that it would be a good idea to run the game with firewall disabled!? My system specs are: Windows 7 64-bit 8Gb RAM Intel i7-3770 3.4Ghz Nvidia GTX 760 OC
