The other day my MacBook Pro just spontaneously halted during regular usage.
The screen went black, aside from the mouse cursor appearing once every 10 seconds (exactly).
I don't seem to be able to move the cursor myself and upon trying to reboot the device (cold), I get the Apple Inc. logo / loading progress-bar combo, and then its straight back to being an unresponsive black screen with a cursor that flashes at ten second intervals.
Does anybody understand what's going on and/or how to fix the problem so that I can resume normal operation? Cheers.

SMC reset worked, but no change. NVRAM reset worked, i think (had to type firmware password) but it brought me to the recovery tools. Cannot boot into Safe-Mode or Single-User-Mode. Apple Diagnostics / Apple Hardware Test fails to launch. Recovery-Mode start-up brings me to the same screen as the NVRAM reset. Verbose-Mode also fails.
