Arthmoor, don't get too upset about me bringing this up AGAIN, looking for some ideas about why the Hotfix 326 and Hotfix 326 CTD for me at the same spot (intersection of the the road to Kvatch) every time, even with no mods installed. I have to say that I am 99% sure it is computer specific.
If it's at exactly the same spot that's likely an indication of a corrupted spawner. Unfortunately if that corrupted spawner is a vanilla spawner, there isn't much you can do about that other than try the usual waiting in the testing cell for 3 days procedure to see if it clears up. The intersection you're talking about sits on the corner of 4 cells, so it's certainly possible. There's several spawners in the area.
The behavior of the crash the Maiq hack addresses doesn't fit what you're describing either since that one tends to happen further to the east. It's never happened at the road intersection.
I'd find it highly unusual for the video driver to be an issue with something this specific. Nor would I expect Win7 to be responsible.
I don't really know where else to go with it at this point. The issue is far too specific for a hardware or OS issue, and the Maiq hack has been solidly demonstrated to fix the major issue in that area.
