It’s actually fine—just using a little more power when not in use. A better approach would be to run a distributed computing program such as Folding@Home or BOINC and avoid letting the PC sit idle from the start. What was your PSU? If it’s quite old, it could shut down because it’s drawing too little power.
This situation involves your PC shutting down unexpectedly due to a power issue. It occurs when you restart your machine without using Windows' shutdown option. In short, your computer stopped working and you had to turn it back on manually. While this error code might not help pinpoint the problem, it works well for most users. C-states functionality has been inconsistent in Windows, especially after recent updates, which could lead to crashes again. You're right about trying to save power when the CPU is idle—it helps a bit—but it doesn't significantly improve stability. If your system has solid cooling (especially with a good cooler for a 13900K), you won't need to disable C-states to avoid crashes. Enjoy your day!
