Startled Computers: Space makes semiconductors surprised

In Sci-Fi movies, androids are often depicted as having cold and emotionless character. We may have such impression because most of computers rely on digital processing in which everything is flatly divided into "1" or "0", but—would you believe it?—they are easily surprised and often get upset. It is caused by a strike of tiny invisible particles, fragments of exploding stars a.k.a cosmic rays, but the shock is significant. The shock makes a computer chip surprised and lose its memory, control, and even its fundamental ability to boot up. So, what will you do next?
