The crash can happen anytime in between looking at the merc/inventory menu for too long, in the middle of a game, at the start of a game, at the end of a game, etc. I noticed that on the Task Manager under Processes the memory usage by DB slowly creeps upwards to 1,550,000 K before crashing.
Definitely not a hardware issue, and my Nvidia drivers are up to date.
So I’ve done some digging, and it seems this might be the reason for the crashes I’ve been getting.

same thing is happening to me but always happens after i pick the mode as it loads or within 1 minute of starting of the training. validated and re downloaded the game but cant get it fixed
Could you please update me on this issue and let me know if this is still happening.
I have sometimes a system freeze! The screen is full of gfx dots and only the reset button will help. Sometimes during game play but in the most cases when I have started a new game by using the server browser during loading the map. 1-3 times the week I guess.
A screenshot is of course not possible when the system is freezed! 
I grabbed my phone and made a photo!

What you see are the residues of the map loading screen.
It was the first game I wanted to start yesterday. Lobby counter went down to 0, the map started to load and I got the freeze in less than a second during loading.
After I have reseted my system, I could play the whole evening without another freeze!
Could you provide the photo in a ticket as I’m unable to view your image.
