Hello
I used to have a laptop with a failing graphics card and whenever I used anything that took too much out of it, google earth for example, I used to get vertical lines or dots then a blue screen. Hopefully yours might be a driver problem but I tried every driver possible and setting and nothing worked. if it is a desktop it should be fairly easy and cheap to change your graphics card though. Mine was a laptop and was a total loss as it was all integrated.
