Weird laptop computer behavior. Was it really User Account Controls?

So, it's a Dell Inspiron, x-64, Windows Vista Home Premium. A couple years old, no problems or issues. I'm fairly savvy and keep things clean, and know how to fix things including nasty viruses.
Suddenly, after the 'Welcome' login screen, the screen would be all black. However, the bottom windows bar ('Start button', date/time, open windows, quick launch) is crystal clear and active (mouseover on an open application and the preview pop-up shows perfectly fine). Also, it seems like the active application window is actually active - responding to mouseclicks and such.
Also, there next to 'Start' is an icon for Switch to New Window and it brings up, showing the desktop as normal, with askew view overlaying the desktop. Clicking just goes back to black. Ctrl-Alt-Del works fine, brings up the normal screen. And selecting task manager, task manager shows up fine.
It's almost like there is a blank black application window open covering everything.
Reboot, etc, etc didn't change anything. Went into Safe Mode and turned off User Account Controls (based on some off the wall suggestion) and surprise it worked!
So, was it UAC? If so, why? If not, what happened?
