my acer laptop has been giving me problems the last few months. Anytime I plug in a USB device or a SD Memory card, the screen blinks on and off repeatedly. Sometimes I have to try and shut it down other times it will stop on its own. Its frustrating. This is really the only problem I have ever had with this laptop. Other than it doing this its pretty much a great laptop. Please help. What could be causing this?
