Troubleshooting Unexpected Shutdowns: My PC Dilemma

Have you ever experienced your computer shutting down unexpectedly? I recently encountered this frustrating issue with my ASUS X670-P WiFi motherboard, which has been in use for about a year and a half. Without any prior warning, my PC would spontaneously power off, leaving me puzzled and frustrated.

One peculiar aspect of this problem is the complete lack of response from the power button afterward. It’s as if my system goes into a deep sleep—only becoming operable again after I cycle the power supply. This prompted me to dig deeper into the possibilities that could be causing such erratic behavior.

I’m reaching out to the community for insights. Have any of you experienced similar issues with your PCs? If you have any thoughts or technical expertise on this matter, I would greatly appreciate your input. It’s always helpful to learn from others who may have faced the same challenge.

Let’s band together and troubleshoot this mystery!

  1. Hi, I understand how frustrating unexpected shutdowns can be. Based on your description, here are some troubleshooting steps to help identify and possibly resolve the issue:

    • Check Power Supply: Ensure your power supply unit (PSU) is functioning correctly. An unstable or failing PSU can cause random shutdowns. If possible, try testing with a known good PSU.
    • Monitor Temperatures: Overheating can cause the system to shut down to protect hardware. Use tools like HWMonitor or Core Temp to check CPU and GPU temperatures during idle and load conditions.

    • Check Event Viewer Logs: Open Event Viewer and look under Windows Logs > System for critical errors or warnings around the time of shutdowns, which can offer clues.
    • Test with Minimal Hardware: Disconnect unnecessary peripherals and only keep essential hardware components connected to see if the issue persists. This can
