Why does the screen suddenly go to many colors?
After turning on my iBook the screen goes to many colors after a minute or 2. They are all square or rectangular and the computer freezes.
I must unplug the compute to let the battery drain.
After the battery has drained, and turned off the computer, I can replug the power cord and in a few moments start the iBook.
The very same behavior will start happening all over again.
Is dit een goede vraag?
