When Windows is starting, I get the blue wallpaper that says Welcome. For an instant, it goes to black, then the wallpaper is back. Then my desktop appears. Not really a problem, but...
I just moved my copy of 7 to a different machine a few weeks ago. I can't remember when it started, or if it's been doing that from the beginning, or if my previous installations did that.
I'm using a Dell LCD that I found on Craig's list. The "video card" is built-in to the motherboard.
I think I may have a video card around here that I could throw in there, just to see if that makes it go away.
