Sounds like your hard drive is dying.
If yes. What about your page files? Sounds like they ´re deactivated. Or your HDD / SDD / MK.2 drive runs out of free disk - space, and Windows can´t create any page file.
You know 16GB sounds much. But it´s not. I got 32 GB and this is barrely enough to deactivate the page files with using of Premiere or Photoshop. :-)
