Check the temperature of the card too.  Try and see if increasing the load on it can trigger the condition.  Also compare the cards diagnostics in Linux and Windows.

Thanks. My suspicion at the moment is that something isn't initialized
properly: usually, the system boots fine and the monitor works; sometimes, the
system boots apparently normally and the screen display is either unreadable
or totally absent. A reboot is enough to fix it.

This phenomenon is very recent; I'm suspecting either a kernel upgrade (one of
the Debian patches) or a developing hardware fault somewhere.
