So I boot up Civ as usual, and start a game. There are no signs of anything being wrong. The game runs smooth, and my computer seems completely okay with it. Then, without forewarning, everything fails. This is at about 60 turns ingame. It starts with the screen going black, and ultimately loosing input all together. The first time I had this bug, the USB ports on my computer even failed.
Anyways, nothing works when the game has crashed. Not CTRL-ALT-DELETE, mouse movements or any other commands. I can't even use the reboot button on my computer, I have to turn it all the way off, and then on again.
This problem came with G & K, and I've never seen anything like it before.
I can upload my dxdiag if you think that will help, but I'm absolutely sure that there's nothing wrong with my computer. Newest drivers and good hardware.
Anything that has to do with threading has been tried, there are no foreign letters, and yes - I have turned the computer on and off
Finally, I've also tried launching in dx9 mode, since some people round the internetz have been telling me that might work. Well, that doesn't even launch. Don't know if there is any correlation between the problems though. Whenever I click "Launch in DX9" mode, the dialogue box disappears for a second or two, just to pop back up. This happens again and again whenever I try the DX9 option.
