Random crash during a huge battle(I was about to win!).
On a side note I had fraps running(not recording).
This was on my desktop, not my laptop.
CPU: Phenom II x6 1055t
GPU: ATI Radeon HD 5870 1GB
RAM: 32GB G.Skill
Game resolution: 2560*1440 (thought this might matter cause it was over 1080p, dunno if there might be issues with higher resolutions)
I grabbed a pic of the crash and what it did to a bunch of my windows:
