    Hello Vượng Vũ,

    Welcome to Microsoft Q&A forum.

    Based on the dump file you sent, BTHport.sys might just be kernel level noise instead of the real cause in this. You can do a quick test to check it, please temporarily disable the Bluetooth adapter when using and see if the issue persists.

    This still pointing to a driver or kernel issue that cause this. Before we proceed further, I also see that VRF_BAD_IP in the failure bucket, which means that Driver Verifier is running. Can you please try to disable it at well?

    • Type "Verifier" in the search bar and press Enter.
    • Select "Delete existing settings"
    • Restart your computer.

    In the meantime, you should also consider updating your BIOS & chipset driver, as well as disable any overclock.

    I'm waiting for your reply.

    The BTHport.sys reference in a blue screen typically indicates a problem in the Bluetooth stack. On Windows 7, a known issue causes STOP 0x0000000A (IRQL_NOT_LESS_OR_EQUAL) when resuming from sleep or hibernation with a Bluetooth device attached. This is tied to Bthport.sys handling connection requests when the Bluetooth device or controller does not return to an active state.

    The documented behavior is:

    • A Bluetooth device is connected.
    • The system is put to sleep or hibernation.
    • On resume, the system crashes with STOP 0x0000000A pointing to Bthport.sys.

    The resolution in the documented case is to update the Bluetooth-related system files (Bthport.sys, Bthenum.sys, Bthusb.sys, Fsquirt.exe) to the fixed versions provided by Microsoft. These updates are distributed through Windows Update or as part of specific hotfix packages.

    Recommended actions based on the documented issue pattern:

    1. Ensure all Windows updates are installed, especially those related to Bluetooth and system components.
    2. Update or reinstall Bluetooth drivers from the PC or motherboard vendor.
    3. If crashes correlate with sleep/hibernate and Bluetooth use, temporarily disable Bluetooth or disconnect Bluetooth devices to confirm the correlation.
    4. If available, run the Microsoft memory dump diagnostic referenced in the documentation to confirm whether the known Bthport.sys issue applies.

    If the system is Windows 11 rather than Windows 7, the exact fix versions in the documentation do not apply directly, but the same principles hold: keep Windows fully updated and update or remove problematic Bluetooth drivers/devices to eliminate BTHport.sys-related crashes.
