Same problem as well. From the event log

Faulting module name: CivilizationV_DX11.exe, version: 1.0.0.20, time stamp: 0x4ca37045

Faulting process id: 0xcb0
Same happend to me, i just reinstalled steam and civ V and it works now again. I think windows 7 sees it as a spyware thing or something. I got crashes after a windowsupdate i think. but the same 0xc0000005 code i had.
i have the exact same problem and my crash usualy happens mid game when i try to move the units the game freezes also if i dont play the game and just let it sit it still crashes. This has been happening non stop even after the fixes recomended by steam forums. Sometimes it happens on turn 5 sometimes i can wait as long as turn 400, but no matter what it happens
