One monitor is plugged in via the DVI port and the other via HDMI.  I think Austin was right that heat may be the problem.  I put a small fan in the case so it blows directly on the video card.  Psensor show the card being around 20°C cooler with the fan than without.   Thanks Austin. and everyone else who responded.

Last time I had a video card lose a fan, the whole system would go into shutdown, so not sure if it's *only* just cooling, but sounds like the card itself, such as the actual output chips are dying/bad.

Are you using any display adapters?  My current system with a Nvidia 1070 card I use 3x DisplayPort to HDMI adapters, and after a week or two of uptime, I'll wake up the displays in the morning for work, and randomly a display won't get signal.  I have to reset the stupid adapter to make it work again.  Really annoying, but could be something similar if you are using active adapters on the outputs too.

    There's a fan built into the side of the case.  I could take the
    side out of the case and put a small fan in there aimed at the
    video card.  Right now Psensor says the video card is at 55°C, but
    I just started the machine a few minutes ago.  After it warms up,
    the card stays around 80°C.  Still, if something in the card is
    going bad, it may act up at lower temperatures than it should. 
    Also it can't hurt to cool it down.

    Anecdotally speaking, nearly all of my electronics have been
    freaking out due to the heat, this includes:

    * google chromecast not playing
    * roku sound going out periodically
    * sonos bridge needing restarting daily
    * VR laptop only works if I put a box fan in front of it

    You problems sound like they could be heat related.  If you have
    a box fan of some sort and you can improve airflow in your
    machine, you might be able to test it.  Or maybe your case could
    be better ventilated.

        I had thought that it might be getting old, but I only bought
        the video card new 3 years ago.  How long should one last? 
        Psensor shows the temperature of the card at 77°C, but the
        specs show the maximum allowed temperature is 102°C.  It just
        started doing this a few days ago.  I guess I could go into
        my parts box and find another video card to put in there
        until I get a chance to buy a new one.

        thanks

        about if it’s a dinosaur.

        For a video
        card, I have a GeForce GT 520.   A few days ago it started
        acting up.
        Now, at random, it acts as if the video card shuts off. 
        Both monitors
        give a no signal message.  However, the software I had
        running continues
        running.  I know this because the dinosaur still plays the
        audio.  The
        keyboard doesn't respond. crtl+alt+backspace doesn't work. 
        I can ssh
        into it, but it won't reboot.  The only thing I can do to
        recover is to
        hold down the power switch until it shuts off, then turn it
        on again.

        Any idea what this might be?

        thanks
