I noticed that Civ BTS doesn't freezes whenever I've closed FireFox and Gtalk and removed a sata drive.
With those 3 items in place the game freezes in random places in any game I play.
The bad thing about that freeze is that I've to reboot and restore my pc to a previous state (otherwise I can't get my internet back) and that it freezes ofcourse
In my current game it has happen twice, I'll restart and remove the SATA HD to confirm my suspicions (it's an movable one)
Edit : ... and it doesn't freeze no more ... after removing it
I installed Civ on another sata drive (in case it matters).
