BTS freezes and make my computer crash badly, with disk errors messages ... It did so with an NVidia graph card and now with an ATI radeon HD 3200. It's not only the game crashing, it screws the computer... It did so with Vista ( NVidia ), XP ( NVIDIA ) and now with the ATI and XP. I gave up Vista, had the graphic card changed, it is worse now than before, it crash after a few rounds ... I just got the ATI from the shop, it's new, with drivers on a CD I would be sorry to have to give up the game, I don't know what to do, I'm scared to start it now. Or does the problem come likely from my computer ? Any help or advise would be welcome, I don't know what to do. Never had problems with Civ before.
