My screen just locked up and displayed the following pattern. Any ideas why?
Hello,
My computer went to sleep and when I awoke it and opened up safari browser, the screen locked up and displayed the attached pattern on my screen. I could still use the mouse but couldn't click on anything. I had to reboot.
Any ideas what could be wrong?
