Actually sounds like a common GPU failure.
Does this unknown model use that Nvidia 8xxx GPU? It was in the news.
Thank you.. It uses the Intel GMA X3100: GPU
Any chance of supplying the exact model?
Now that I have one more clue I've seen this with non-standard RAM in many Intel GMA solutions.
MacBook 3.1.... late 2007, dual Intel core... Please let me
Thank you. Please let me your thoughts or if you need more information.
I'm thinking non-standard RAM. The Intel GMA has been spotted to do that when the memory is not up to the task.
-> But why didn't you reply to that idea? You should know if something is not stock there.
The next idea is heat. Tell us about your yearly canned air cleaning.
Think I found a solution
You are correct that I installed new RAM several months ago, but The black box only started appearing a couple weeks ago. The solution that seems to have solved the problem was under System Preferences... Universal Access.... Seeing. The mystery is that I had never changed any of the settings under Seeing before. I continue to think that a Plug-in or App somehow changed something in preferences. I made some changes to the preferences and the black box has stopped appearing so far. Thank you for your help. Sorry I couldn't get back to you right away.
