Frequent BSODs

Hello,

I’ve recently been experiencing frequent BSODs on my Lenovo Legion 5 laptop, but only when I am connected to an external monitor via HDMI. Without the monitor, the system is stable.

The BSODs are now freezing at the blue screen instead of rebooting, forcing a manual shutdown.

System Information

  • Model: Lenovo Legion 5

CPU: AMD Ryzen 7 5800H

GPU: NVIDIA GeForce RTX 3050 (4GB)

iGPU: AMD Radeon Graphics (APU)

OS: Windows 11 (fully updated)

External Display: Connected via HDMI

BSOD Details

The system has shown multiple bug checks, including:

0x0000007E – SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

0x0000001E – KMODE_EXCEPTION_NOT_HANDLED

0x0000003B – SYSTEM_SERVICE_EXCEPTION

The BSOD usually mentions a failing .sys driver file, but it flashes too quickly to capture. The last two days the BSOD freezes entirely.

Troubleshooting Already Performed

Used DDU to completely remove both AMD and NVIDIA display drivers

Reinstalled:

Correct AMD APU drivers for Ryzen 5800H

  Latest NVIDIA Game Ready Driver
  
  Updated BIOS and AMD chipset drivers
  
  Disabled Windows **Hardware-Accelerated GPU Scheduling**
  
  Disabled browser **hardware acceleration**
  
  Tested multiple HDMI cables and ports
  
  Set external display to 1080p 60Hz, disabled HDR
  
  Verified no overclocking
  
  Ran `sfc /scannow` and `DISM /restorehealth` (no major issues found)

Despite all this, the BSODs still occur only when the HDMI monitor is connected.

Additional Context

Laptop display alone works with zero crashes

External display triggers crash within minutes to hours

Reliability Monitor shows repeated Windows Hardware Errors and BlueScreen events

Appears related to a GPU handoff/driver conflict (possibly nvlddmkm.sys, amdkmdag.sys, or dxgmms2.sys)

Request

I would appreciate help determining which driver or subsystem is causing the .sys file failure during HDMI display mode switching.

I can provide the following upon request:

Minidump files (C:\Windows\Minidump)

Full MEMORY.DMP

msinfo32 export

Reliability Monitor screenshots

dxdiag report

    Please upload any minidump files you have, I will check those to see if they provide any insight into a potential cause of the system crashes.

    Please do not upload the large Memory.dmp file.

    Open Windows File Explorer.

    Navigate to C:\Windows\Minidump

    Copy any minidump files onto your Desktop, then zip those up.

    Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

    Then post the link here to the zip file, so I can take a look for you.

    It seems that your Lenovo Legion 5 is experiencing frequent BSODs specifically when connected to an external monitor via HDMI. Based on the information provided, here are some potential troubleshooting steps and considerations:

    1. Driver Conflicts: Since the BSODs appear to be related to GPU handoff or driver conflicts, you might want to ensure that you have the latest drivers installed for both the NVIDIA and AMD graphics. You mentioned using DDU to remove drivers, but it may be worth checking if any new updates have been released since your last installation.
    2. Check for Faulty Drivers: The specific BSOD codes you mentioned (0x0000007E, 0x0000001E, 0x0000003B) often relate to driver issues. If you can capture the specific .sys file mentioned in the BSOD, it could help pinpoint the problematic driver. You might want to enable kernel memory dump to capture more detailed information during the crash.
    3. External Display Settings: Since the issue arises only when using an external monitor, ensure that the display settings are correctly configured. Try different resolutions and refresh rates to see if that alleviates the problem. You mentioned setting it to 1080p 60Hz, but testing other settings might yield different results.
    4. Hardware Compatibility: Verify that the external monitor is compatible with your laptop and that there are no known issues with using HDMI on your specific model. Sometimes, specific combinations of hardware can lead to conflicts.
    5. Event Viewer: Check the Event Viewer for any critical errors or warnings that coincide with the times of the BSODs. This might provide additional context about what is failing.
    6. Memory Diagnostics: Although you ran sfc /scannow and DISM, running the Windows Memory Diagnostics tool could help identify if there are any underlying memory issues that could be contributing to the crashes.
    7. Contact Support: If the issue persists, consider reaching out to Lenovo support or checking their forums for any similar issues reported by other users. They may have specific patches or solutions for your model.

    If you can collect the minidump files or the MEMORY.DMP, analyzing those files with debugging tools like WinDbg can provide deeper insights into the root cause of the BSODs.
