Computer crashes

I am very lucky (I hope I am not jinxing myself) that I have never experienced a total crash. My computer is a laptop from the school and we have a great tech department that take scare of everything. All my data, etc is stored on the school server, so if that ever crashes – I’m dead. My daughter has taken her computer to the “geek Squad” at Best Buy to fix problems and it usually come back with different problem that results in a second trip! Since losing many pictures, she bought an external hard drive and backs up her data.
