That's a kernel panic (the equivalent of a crash).
This article explains a variety of possibilities on what could be causing this.
Does it happen when you're running specific programs?
It never happens when I'm on the computer ONLY upon waking. I wake it up and I automatically get that little screen. It's been happening every single time now.
read the article. The only thing I could really see was in my login items. there was something else in there which I got rid of. Repaired permissions and re-started.
Strange thing.... I LONG ago dumped items that I would never need or use like itunes and imovie. Well, they are back. Safari is also back which I didn't have before. Those items had to be put on at the repair shop. What the hell??? What else should I look for?
I'm looking for any third party programs -- that was something else they suggested in the article but so far I'm not finding any.
