Last year there were 5 instances when my laptop showed the blue screen. It said it encountered a fatal error that it would be restarting. I was not able to take a picture of the screen so I do not know the details. This year, so far, the blue screen had not appeared yet. The laptop is running on Windows 7 so I am thinking that maybe it needs an upgrade. Do you have an idea on what may be causing the appearance of the blue screen?
