Resolved: So while the game was loading up I accessed "GlimpseGame"" (startup programs) properties and changed the compatibility to windows 7. Almost called this a Win... Then my PC blacked out again about 40 seconds into gameplay. (Clearly what caused me to black out crash to start / boot menu is still a problem. Not sure how widespread Black Screens of Death are.)
What didn't help:
I fixed Windows 7 direct x 11 just to be sure. (This had no affect and I was unable to launch the game after "fixing" it) So scratch that theory.
My temperatures on the PC are fine when I run other games... I will be investigating what happens to my Temps when I run WHF again in the future... (when I can actually get into the game for a period of time. But hey at least the launcher works now.
