I would seriously consider changing the graphic card, at least to make some tests. From many posts I read about Vue problems, the graphic card seems to be at the center of many of the problems. In your specific case, Vue even alerted you about compatibility issues. Maybe you can get a borrowed card from some friend or even from a store.

Did Vue crash always with the same scene or did you change scenes? Or maybe it could be something in common with all the scenes, a specific object or so. Do you have boolean objects or metablobs? I didn't try any of these in V7 yet but I had some occasional problems with it in V6 when rendering. To minimize it, I normally kept the mini preview window with auto-update off and baked the objects as soon as I could. Maybe you can try it.
