Gina is getting a blue screen on her Mac. Eventually the computer comes back, but she wants to know Why? Leo says that it could be a problem with an external peripheral. Unplug everything except your keyboard and mouse, and see if it repeats. It sounds like a communication issue between your peripherals. A bad driver or a failing USB port. Then plug each extra device in, and see which one causes it. Then you'll know which device is causing the problem, and then you can go to the website and get an updated driver.
