I have been playing the game on a Dell T5600 for about a year. No problems.
Recently, there was an update from Dell.
After that CW2 begins to load, gets to the 52% loading textures (or therabouts) and then a message pops up indicating the CW2 has stopped working. No errors, not explanation.
The mainlog does not show any errors that I can see.
So I uninstalled and then reinstalled the game via Steam and the game again ran for 2 sessions.
When I tried to initiate the game again, it is back to the same problem as above.
I have done this twice now and can duplicate this exactly. By uninstalling and re-installing I can get the game to run for 1-2 sessions and then it stops working again.
Since there are no error messages, I don't know where to begin trying to troubleshoot the system.
