Kernel Power Error, Desktop Shutdown Once Daily

[mikesky]

HP desktop randomly shuts down once every day (no pattern, it happens at various times).  When I check Windows event viewer it shows "event ID 41, Task (63) source kernel-Power".  Error code varies, such as (0x50), (0x139), (0x13A), (0xA). I've tried all of recommended repair steps such as: updating drivers & BIOS, adjust & disable auto restart, ran HP Hardware Diagnostics, ran sfc/scannow, extensive SSD hard drive tests, processor tests, system board tests, TPM test, etc.  

Thinking it may be overheating, I even tried a small desk fan giving additional ventilation to the HP cabinet vent holes.  After trying this for 3 days, the desktop still shut down randomly every day.  

As a last resort I purchased & installed a new HP power supply unit.  Problem still continued.

I don't do any gaming or heavy usage computing, just normal home usage.  

This desktop is 2 years & 8 months old. It has had no issues prior to this.

I use Google Chrome & Microsoft Edge a lot for normal browsing & internet searches.  Could they be corrupted?

Hi @mikesky,

Welcome to the HP Support Community!

I understand that your HP desktop is shutting down unexpectedly about once per day, with Kernel-Power Event ID 41 (Task 63) being recorded. Since you have already updated the BIOS/drivers, replaced the power supply, tested the SSD, processor, system board and TPM, and checked for overheating, you've already covered many of the common causes.

Regarding your question about Chrome or Edge: a corrupted browser installation would not normally be the first suspect for a complete system shutdown. However, if the shutdowns occur while browsing, it is worth checking whether a specific application or driver is triggering the failure.

As a next step, please try the following:

Check the Reliability Monitor

• Press Windows + R, type perfmon /rel, and press Enter.
• Look at the day and approximate time of the shutdown.
• Check for any Critical events or Windows failures immediately before the Kernel-Power event.
• If you see an application or driver repeatedly failing, please share its name.

Test the system without the browsers

For one day, avoid using Chrome and Edge if practical and use another basic application for normal activity.

If the shutdown still occurs, this makes a browser-specific cause less likely.

Check whether Windows is generating a bugcheck

Open Event Viewer > Windows Logs > System.

Find the Kernel-Power Event ID 41 entry and check the BugcheckCode and PowerButtonTimestamp values in the event details.

Since you are seeing different codes such as 0x50, 0x139, 0x13A and 0xA, please share those values from the most recent event.
 

Because the system has already had the power supply replaced and the HP hardware diagnostics have passed, the additional Event Viewer/Reliability Monitor information will be useful for narrowing down whether Windows is experiencing a driver/software crash or whether the shutdown is occurring at a lower hardware/power-management level.
