lol - pretty sure you've been here before, yes - if I were you, I would do a complete uninstall of Origin and SimCity. When you reinstall, do both "as administrator".
I see by your dxdiag report that you have GTX 970 video card. I *think* I've seen some issues on the board regarding that particular card. You might want to search the board for that specific board to see if there's anything else we haven't tried. There's also an error related to steam listed - I honestly am very bad at reading dxdiag reports in general, and even worse when it's not in English (I so admire you for being able to converse in English when your first language is Danish - wish I were that talented).
Anyway, I'm going to page my favorite troubleshooter
