About 2 weeks ago, I opened up the computer and blew off the dust inside.

It hasn't turned off by itself since then.

One possibility is that the computer was in sleep Mode and not actually shut off. There are several ways to power off, one is to power off after updates. Update and Restart but you may need to check other power saving settings which save your display screen from burning an image.

If you actually visualized a cake-type buildup on your CPU fan and also your graphics card (if you have an add-on graphics solution) and you generally saw copious amounts of dust everywhere --even on and around your power supply's fan, then you likely have your answer. Blowing off huge amounts of dust buildup can free your system fans (all of them) to be able to properly cool down your system and not auto-shutoff due to a hot temperature threshold meltdown. Heat is the bane of electronics someone once said. It happens to be true.
