    This has happened maybe five times, twice in the last month.

    I'm just sitting there reading a web page (in Firefox, btw), and the screen goes grey/gray from the top down and this message appears. This time I took a photo of it, as otherwise the computer is totally unresponsive.

    Can only use the power off/on button.

    Help!

    The only time I have had that problem was when I upgraded the memory in my mac mini, turned out one of the modules was faulty. Took it back to the shop and got it changed, no more problems.

    Hope that helps.

    I did upgrade the memory, but that was a few years ago, and seems unconnected to these fairly recent events.

    I would say the last time was about ten days ago.

    Try reseating the memory. Or you may just have a faulty module. If it gets more frequent experiment with taking out one stick at a time to see if you can isolate the faulty one.
    Also look in the system log, there may be a diagnostic error in there
