VISTA games not working and a few questions about Vista

Well, I posted before that I was having a problem installing Vista but somehow by adding another drive to my computer but not even using it I got it resolved kind of awkward. Well now my problem is for some reason all of the games under vista crash except for InkBall. It's kind of a weird problem. If anyone has a solution please respond. A questions I have is DRM. What is it and does Windows Vista have it? What will it not allow me to do? Thanks.
