Crashing and Blue Screen while playing WoW.

I tried to find the log that went with the crash and I think this is it, but it is always crashing. If this isn't it, I'm pretty good at understanding where things are if you tell me. I just want to get down the to the bottom of what the problem is. I can say one thing, I have a 64 bit system, but programs are running in 32. Was this an install problem? Any help would be appreciated. And this keeps happening and I didn't know if it was from the fall issue... see, I've done a lot of reading, but I don't know what goes with what. so I'm trying to understand. Any and all help would be appreciated. 

And sorry if this makes any of you coders laugh.... I'm obviously new at this.
