Crashes at startup

[arges86]

Civ 5 worked just fine since it came out (i installed it then).
It started crashing yesterday. It will run on Direct X 9 (windowed) and it lags allot with pixels rendering incorrectly.
In Direct X 11 mode, it crashes as soon as the 2K logo comes up.

I have the latest nVidia drivers, as well as the latest Direct X version.

I've tried disabling the start-up video in settings.

I uninstalled the game, deleted any residual files and re-downloaded it from Steam.
still no luck.
I searched allot of forums, and still couldn't find any solutions (most posts were from 2010).

My computer is:
AMD: Athlon 64 X2 5200+ 2991 MHz
Mobo: Gigabyte M57SLI-S4 v.2 (with latest BIOS)
RAM: 4GB Mushkin DDR2 PC2-6400
OS: Win 7 64bit
VC: Geforce GTX 470

Thanks for any help guys

might be steam problem with detecting the game and lead to crash or lags, or other third party tool that detects D3D applications (fraps, msi afterburner, xfire).
post your problem to steam support they might help you with it.
