Experiencing a recurring Blue Screen of Death (BSOD) when joining Teams meetings on a laptop. The issue started a day and a half ago, and even after a complete wipe and fresh installation of Windows 11 64-bit, the problem persists.

The specific Stop Code encountered is: IRQL_GT_ZERO_AT_SYSTEM_SERVICE.

The minidump file indicates the following:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000004a (0x00007ffbe0f01eb4, 0x0000000000000002, 0x0000000000000000, 0xfffffe84561ffaa0). A dump was saved in: C:\WINDOWS\Minidump\071025-18765-01.dmp. Report Id: c9ef9555-9725-4490-9738-697221822c7f.

The error occurs even when the laptop is removed from a dockport. Any guidance on troubleshooting this issue would be greatly appreciated.

    Hi Manish Rohila

    Thanks for reaching out to Microsoft Q&A forum support

    Based on your description, I understand you are encountering a BSOD error when joining Teams meetings or when removing your laptop from the dock port. As far as I know, and based on the error codes you’ve provided, I believe the issue may stem from conflicts between system-level services and hardware drivers.

    As I am a forum moderator, unfortunately, I don't have the necessary resources or access to provide a precise solution to this issue. However, I have conducted some research and identified a few potential approaches that might help resolve the problem. You can try the methods listed below to see if they help fix the issue. 

    Option 1: Driver Update/Roll back 

    Even after a fresh install, some drivers might not be fully compatible with your system or may require updates: 

    • Go to Device Manager (press Win + X and select Device Manager). 
    • Look for devices with a yellow exclamation mark (indicating a problem). 
    • Right-click on the device and select Update Driver. 
    • Alternatively, visit the manufacturer’s website to download the latest drivers, particularly for the audio, network, and graphics drivers, as they tend to be sources of these issues. 

    If the issue started happening after a recent driver update, try rolling back to a previous version: 

    • In Device Manager, right-click the device and select Properties. 
    • Under the Driver tab, select Roll Back Driver if the option is available Option 1: Driver Update/Roll back 

    Option 2: Run Windows Memory Diagnostic 

    • Press Win + R, type mdsched.exe, and hit Enter. 
    • Choose Restart now and check for problems. 
    • Windows will check your memory for errors during the restart process.  After the check, Windows will display the results and inform you if any memory issues were detected. 

    If memory issues are found, it could explain the recurring BSODs, especially during memory-intensive tasks like video conferencing. Replacing faulty RAM or fixing memory errors can often resolve BSOD error. 

    Hope you will solve your problem soon, if the issue still persist, kindly let us know in the comment
