Yeah, i'm down to barebones security updates myself. Good news! I'm fixed! It took several days of intensive Googling and some thinking outside the box, but i am back in business, woohoo! Turned out, it was the video driver, and i had to find a way to uninstall it without letting the automatic reinstall wizard put it back, because it kept doing it wrong. One manual install later, and voila! The Youtubes are back. Yaaaaay.
