Solved unexpected shutdown no error code or message

Specs: Windows 10, 8GB DDR2
My pc started randomly shutting down. No error message or code explaining why. Only error came from Google Chrome, stating that it was improperly closed (maybe shutdown) and asked if I want to restore the pages. I replaced the power supply, and that appeared to correct the problem, then about 3 days later it started randomly shutting down. Sometimes it happens when my son is watching videos on YouTube. He did say that it's usually one channel that this happens on, but I've found it happens when I'm just reading an article or even just posts on facebook. Before I installed a new power supply, it was suggested that it was over heating, and I could tell that the fans seemed to be running a little louder, possibly the fans were working harder. I specifically googled power supply upgrade for Gateway DX4300-15a, and purchased it. I googled my issue, and found this website.

✔ Best Answer
When was the last time you blasted out all the accumulated dust from inside the case with a can of compressed air?

I do mine 3 or 4 times a year.

The components and fans get caked in a thick layer of dense dust over time and this can cause overheating which is a classic cause of a PC shutting down with no warnings or error messages.
