I was using my Asus laptop Tuf gaming a15 FA506ICB for taking an exam in canvas while on a meeting with my camera on then my computer crashed then reboots (BSOD SYSTEM_SERVICE_EXCEPTION (3b) MODULE: AuthenticAMD.sys) and after I typed in my passcode, it crashed again this time its KMODE_EXCEPTION_NOT_HANDLED (1e) (PROCESS_NAME: RuntimeBroker. IMAGE_NAME: ntkrnlmp.exe).

And as I was typing this, another BSOD occurred KMODE_EXCEPTION_NOT_HANDLED (1e) 

PROCESS_NAME:  svchost.exe

IMAGE_NAME:  ntkrnlmp.exe

    Hi, I'm Bernard. I'm happy to help!

    The AuthenticAMD.sys error means that the AMD driver or the processor itself may be causing the issue on the PC. In this case, kindly download and install the latest BIOS update from your manufacturer's website. Moreover, if the issue persists, we will check and make sure there are no software-related issues. I suggest doing an in-place upgrade,, wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

    Go to the Windows 11 website: https://www.microsoft.com/en-us/software-download/windows11

     

    Under Download Windows 11 Disk Image (ISO), select Windows 11 (multi-edition ISO)

     

    1.    Once done downloading the ISO, kindly right-click on the ISO, then click Mount> click Setup.exe

    2.    You may be prompted by User Account Control. Click on Yes if so

    3.    In the Install Windows 11 dialog, click Next

    4.    Setup will check your PC and show a license agreement. Click on Accept in the license terms dialog.

    5.    Wait for the setup program to check for the available free space.

    6.    On the Ready to install page, make sure Keep personal files and apps have been checked.

    7.    Then click Install and just follow the prompt.

    8.    Windows 11 will restart your device several times and lead you to the lock screen. Depending on the options you set, it will keep all your files, apps, and user accounts.

     

    Method 2. Install and run AMD Software: Adrenalin Edition Application, then update the drivers.

Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.

    Note: If the issue persists, I suggest contacting a local technician to physically check the processor or do a re-paste of thermal paste to optimize the processor.

    The stop codes SYSTEM_SERVICE_EXCEPTION (0x3B) with module AuthenticAMD.sys and KMODE_EXCEPTION_NOT_HANDLED (0x1E) with ntkrnlmp.exe typically indicate a faulty or incompatible driver, system service, or firmware issue, often related to CPU/chipset or other low-level drivers.

    Follow these steps in order:

    1. Remove or update recently added drivers or software
    • If any new device drivers, utilities (e.g., OEM tools), or system services were installed or updated recently (before the first BSOD), uninstall or update them.
    • Focus especially on AMD-related components (chipset, CPU drivers, OEM “defender/crash” tools) and any hardware monitoring or overclocking utilities.
    1. Check Device Manager for driver problems
    2. Open Device Manager.
    3. Look for any devices with an exclamation mark (!).
    4. For each such device:
      • Open Properties → check Events/General for errors.
      • Try Update driver.
      • If that fails and the device is non-essential, temporarily Disable or Uninstall it.

    (From bug check guidance, devices with issues or outdated drivers are common causes.)

    1. Check Event Viewer for correlated errors
    2. Open Event Viewer → Windows Logs → System.
    3. Look for critical or error events around the times of the BSODs.
    4. Note any recurring driver, service, or firmware names; update or disable those components.
    5. Update BIOS/firmware and confirm hardware compatibility
    • On gaming laptops, outdated BIOS/firmware can cause kernel exceptions and ntkrnlmp.exe-related BSODs.
    • Install the latest BIOS/firmware from ASUS for the TUF Gaming A15 FA506ICB.
    • Ensure all hardware is supported for the installed Windows 11 version (refer to Windows 10/11 hardware requirements as guidance).
    1. Update AMD chipset/CPU drivers
    • Install the latest AMD chipset drivers and CPU-related drivers from ASUS or AMD for this model.
    • If there is an AMD “Crash Defender” or similar service (e.g., Amdfendr), and BSODs reference AMD modules, temporarily disable that service to test stability, as similar issues have been resolved by disabling AMD crash defender components.
    1. Basic blue screen troubleshooting for Windows 11/10 Apply the general steps used for recurring BSODs:
    2. Remove any newly added hardware (if any) and test.
    3. Ensure there is sufficient free disk space (at least 10–15%).
    4. Install all pending Windows Updates.
    5. If BSODs started recently, use System Restore to revert to a point before the crashes.
    6. Advanced debugging (optional, for advanced users) If comfortable with WinDbg and kernel debugging:
    7. For SYSTEM_SERVICE_EXCEPTION (0x3B):
      • Use .cxr with parameter 3, then kb to inspect the stack.
      • Use !error on parameter 1 to decode the exception code.
      • Use lm t n to list loaded modules and identify non-Microsoft drivers near the fault.
      • Use dx KiBugCheckDriver to see if a specific driver is recorded.
    8. For KMODE_EXCEPTION_NOT_HANDLED (0x1E):
      • Analyze the dump with !analyze and inspect the stack for third-party drivers.
    9. Use Driver Verifier carefully (advanced)
    • Driver Verifier can expose faulty third‑party drivers by stressing them.
    • Only enable it for non-Microsoft drivers and be prepared to revert (Safe Mode or verifier /reset) if boot issues occur.
    • Use it only after creating a restore point and backing up important data.
    1. Memory and hardware checks
    • Run the Windows Memory Diagnostics tool to rule out RAM issues.
    • Run OEM hardware diagnostics (especially for memory and CPU) provided by ASUS.
    1. If BSODs persist
    • If all drivers, BIOS, and Windows are updated and BSODs continue, consider a Reset this PC with “Keep my files” to reinstall Windows while preserving personal data.
    • If even that fails, a full factory reset or clean reinstall may be required.
