Debugging Random shutdown of Windows

I recently faced the problem where my Windows machine would randomly shutdown. No warning, no messages!

However it would consistently shutdown everytime randomly.
Interestingly using the power button wouldn’t restart it either. I would have to take out the power cord and plug it back in after few seconds. Then the power button would function normally.
I suspected SMPS as the culprit, specially because it required me to unplug the power and plug it back again before working. So I changed the SMPS couple of hours ago.
So far it looks like my hunch is correct.

This is related to the .theme pack you are using. If it corrupt in any way, or has power settings inside it that were customized, then it causes a hard shutdown of the CPU. The power to the motherboard is still on, but it takes a discharge to restart the computer (unplug from the wall for 10 seconds or so). I had the same problem and found this out the hard way; it can also be if your desktop background files are very large and a screensaver is invoked under power saving conditions. Change the theme to a basic one, and no problem; switch it to one that has several new settings related to power and screen saver and POW, off you go. I have a theme I can select and the machine immediately shuts down, and needs an unplug to work again.

that would be a really funny geek joke, except i’m afraid you actually meant it.
