I have a problem...

My PC keeps crashing at certain points in the game! I'm not sure why, but I think it has something to do with my graphics card-- NVIDIA GEFORCE Mx 440. I belive its 64mb.

But the thing is, I can play the regular version of WarCraft, and other versions of Dota on my PC. It's only the AI map that gives me problems. It crashes no matter what side I use, no matter how low my settings are, and no matter how many bots I put in. And it crashes at different times in the game, so I can't figure out what's giving me the problem.

Did I miss something? Help would be very much appreciated!
