Bad science fiction memes

Now, I admit, this one is most often seen in movies rather than in 
books, but...

....how many times has it been done that when a computer receives 
information about a problem it can't decipher and "overloads" it then 
explodes, taking whole buildings (if not cities -- I'm watching a couple 
minutes of "Logan's Run" here) with it?
