I have created a new thread as necroposting is not really welcome.
Neither is trying to hijack threads, so keep it to this one.
In order to help us help you we need quite a lot of information:
What where you doing when the game crashed?
Which map and game mode where you playing?
Do you have any mods installed?
In case you crashed on zombies, which difficulty did you play on?
Do you have any overclocks applied?
Do you have any DirectX overlays?
What Exception Code did you get?
What Exception Address did it show?
The dump file (check %LOCALAPPDATA%\Plutonium\crashdumps)
If you really don't have any crashdumps it simply means it is not crashing but gets closed by something on your PC.
