If it was truly random when this ^^ happened, and not after starting an app without aero support, then it sounds like her display driver probably crashed. There's usually a little balloon too stating "the display driver stopped responding and successfully recovered" or something along those lines, although this hasn't always appeared when it's happened to me.
You could always check the system event log (control panel>administrative tools>event viewer, then look under Windows logs>system) and try find any warnings that match the time it appeared.
