Memory exhaustion with apparently no process exhausting it

Question

I am suffering memory exhaustions on a Windows 10 computer nearly every three days, with no pattern to reproduce (sometimes after PC is powered on for days, sometimes just after power on, sometimes under normal usage, sometimes under heavy load, sometimes while quiet...). The symptoms are recongnizable: the video driver crashes and the resolution goes to minimum, then sometimes some process like firefox or chrome closes...

When this happens, processes RAM consumption under task admin seems normal. Under system events I can always see a Memory Exhaustion Detector event which seem to fail to explain the crash, because it always shows the paging file to be enormous and about to explode, but it also shows no process eating that memory.

Is there any reasonable explanation? Am I failing to interpret the log entry?
