Just as the title says, when I load the User Preferences, Blender flips out, and the GUI flickers and buttons disappear. Some of the windows even go pure black. I tried uninstalling the current version of Blender, and tried using an older version of Blender, thinking it was just that this build being unstable. But when I used Blender 2.64, which I had never had issues with, same thing happened. Is this a driver issue? And if it is, where can I go to update my drivers?
