Makes it non functional, so unable to do anything other than turn it off. Even then I have to force it to by holding the button down. I'm not sure if I'm using the word crash right. No blue screen or anything like that.

Well, the game shouldn't really cause any damage, unless it is overheating specific parts of your computer, which may—or may not—be caused by the settings set to max, if it's happening at all. The game isn't the best in terms of optimization, so it is likely not a wise decision to have everything set to max. I would suggest keeping graphic settings default to see if things work from that point. If that doesn't work, it may be something else going wrong.
