Looking at the dxdiag you are on Windows Th1, if you do update to Th2 there is an issue at present that causes BSOD ingame, so if you do theis update put grass to 0 until fixed, this will stop the known crashing.
now I cant see the bios version but can see the EC is outdated not sure if you want to muck around updating this. (not related to this issue)
looking at the NVidia driver the latest is here
moving down to the client_settings file , delete the following lines to see if any impact
DYDDrawDistancePreset = 2 and AmbientNPCCount = 35
Now in game have you played with any settings ? see if turning AA off altogether has any affect and if any change between fullscreen mode and fullscreen window mode.
once seeing if any change at all can proceed from there
