Recurring KERNEL_SECURITY_CHECK_FAILURE (0x139) — extensive troubleshooting completed, driver/RAM/disk/AV ruled out

All Over Plant Hire - Administration Department 0

I'm experiencing recurring BSOD crashes on my HP Victus 15L Gaming Desktop (TG02-0016a) running Windows 11, occurring almost daily since 16/07/2026.

Consistent bugcheck details:

Stop code: 0x139 (KERNEL_SECURITY_CHECK_FAILURE), parameter 0x1d (RBTree corruption)
One dump also flagged FLTMGR.SYS as involved
One separate occurrence of 0xA (IRQL_NOT_LESS_OR_EQUAL)

Already ruled out:

CHKDSK - clean
Windows Memory Diagnostic (Extended) - 0 bad pages
SFC /scannow and DISM /RestoreHealth - no corruption found
Bitdefender fully removed for 24+ hours - crash still occurred
NVIDIA GPU driver rolled back (610.88 to 596.49) via clean DDU removal - crash still occurred, identical signature
No flagged hardware in Device Manager

Home diagnostic tools (WhoCrashed) cannot resolve a specific offending driver beyond the generic kernel module. I have minidumps and a full kernel memory dump available and can share via OneDrive if that helps with proper WinDbg-level analysis.

Dad had the same issue with the same model. The solution that seemed to help was backing up everything (i.e. personal files, program install files, etc.) and then doing a full factory reset with all the drives checked for a full clean.

Hello,

When your computer crashes with a blue screen, we need a .dmp file to analyze and locate the blue screen error. The minidump file path is: C:\Windows\Minidump

If your computer doesn't have this file, you need to make some settings:

Open Control Panel - System and Security - System - Advanced system settings - Startup and Recovery.

Set "Write debugging information" to "Small memory dump 256kb" and "Small dump directory" to "%SystemRoot%\Minidump".

After setting, restart your computer. The next time your computer crashes with a blue screen, a new file will be generated. You can then upload the blue screen file to OneDrive and provide a download link.

Or other cloud storage services.

Hi @All Over Plant Hire - Administration Department

May you send the minidump files by going into C:\Windows\Minidump and upload it to the cloud?

And choose to share those and get a share link and share/copy the link to here.

That would be very useful to diagnose.

Best regards,

Nanta

Hi @All Over Plant Hire - Administration Department

Thanks for the follow up!

In the meantime, while my computer is analyzing the mini dump file, in Event Viewer on your computer, go to Windows Logs > System. Is there any errors regarding the BSOD and any other relevant errors?

Best regards,

Nanta

Hi @All Over Plant Hire - Administration Department

I dug in into your dump file, and the kernel detected a corruption in a critical data structure.

Try to run MemTest86, you can download it from this link: https://www.memtest86.com/

Alternatively, you can search in Windows "Windows Memory Diagnostic" (Though misses some errors).

If there are errors, the only repair is to replace the RAM Stick.

Also, reset your BIOS/UEFI Settings to default.

And try to make sure your drivers are up-to date by the manufacturer's website.

Hope this helps!

Best regards,

Nanta
