Many many users have problems with Civ4 locking the PC completely. It seems like a lot of these users have Radeon video.
Several users (myself included) have reported that the problem can be helped greatly by turning off AGP in the Catalyst Control Center (under advanced->smartgart slide AGP speed to 'off'). Reboot required.
After making this change, I saw no decrease in game performance or game movies/animations. Game freezing stopped almost completely.
Notes:
- I could not load saved games from before the change. Saved games after the change worked fine.
- I did still have a freeze. One freeze in 4 hours of play. (previous to AGP change, freezing occurred every 5-10 minutes)
So give it a shot! Remember to turn AGP back on for other apps/games.
