Frustrating Problem with Crashing

It's such a long time ago, I had forgotten why I left the game last time. But now I remember, it was the fact that for some reason I would randomly crash in this one mission. I'm not sure whether crash is the right technical word, because the game just freezes and then when I C-A-D it tells me that my display driver stopped functioning. It's an ialmrnt.5 if that's any help. But yeah, I've been looking everywhere for solutions with no luck so far, I'm currently downloading some driver updating software while talking to one of my more computer-savvy friends at the same time as I'm posting this. As you can see, I really want to get this fixed.

Oh, and it is one specific mission, because I've played through another mission with a different character and an AE arc on the same character. They didn't crash. But for some reason I don't think it actually has anything to do with the mission, but I'm not really sure. It's a Psimon Omega mission with the objectives: Steal Components, Defeat All Guards. Oh, and I have an inbuilt graphics device/card called Intel(R) 82865G Graphics Controller.
