Have you gone back to the game to make sure it crashes again in the same spot?

Not only restart, but also loading saved game should suffice. If it will crash on the same spot, it can be a problem in the mission script or something like that.
Otherwise it can be a random crash. I remember my retail OW crashing from time to time.

When did the crash occur? While doing mission or durring debriefing?
I experienced few crashes durring debriefing but my progress was already saved so hardly lost anything and could progress in game normally. As far as I can recall I never experinenced crash durring mission.

Yea thats what I meant did you try it again to see if its a consistant crash or just some random bug. Even if its tedious it might be worth playing through again, saving often if possible and then seeing if it happens again or its a one time occurance.

Have you got unoficial patch? 1.10 i think?
It's beacause of patch.
1.10 start crashed when i do something... non-standart. It's happened me few times. My original - vanilla - game (1.02) never do that.
Edit: Yes, obviously you have 1.10b

The proper place to post Error Logs is at http://forum.owsupport.com (GOG does not have the source code so they can not help). Tho i can only trace access violations in v1.11 Beta. (1.10 is 2 years old)
If you don't care about multiplayer then id recommend joining the Open Beta Test and downloading version 1.11 . (1.11 is not compatible with 1.10 online, so you can't play against people who have 1.10)

Strange, should work. I got the same equipment, same CD version patched to 1.10b and it's running smoothly.

May it be compability issues.
But more probably RAM in your computer. 1280 MB? Is this 512+ 512 + 256? Is that so, I am more than sure, that this 256 MB RAM chip is malfunctioning. Guess, those 512 got 333 FSB and this 256 got 266 FSB??? Remove 256 MB RAM chip and after that - PLAY.

Access Violations mean that the Game is trying to access something that doesn't exist. Meaning that it never created something but is trying to use it as if it was created. There is a 99.9% chance that the problem is a bug in the game rather than a hardware issue.
