The Windows black-screen-and-fans thing might not be related. I got a (second) FW16 about six weeks ago, and while trying to install Windows on it (not my choice, it belongs to my employer), that’s exactly what I got after the first installation reboot.
As I recall, I finally got past it by forcing it to shut down a couple times, waiting fifteen or so seconds before restarting it each time. Eventually it came up with a screen with repair options. One of those options, under a couple layers of clicks, actually worked and let the system finish installing. Haven’t had any problems with it since.
That said, it does sound like you’re having other issues. Have you tried this yet? It’s not a cure-all, but it does cure a lot of things.
