    If your laptop only crashed once, then Windows may have been updating in the background and that caused a temporary conflict, and there is nothing further you need to do.

    If this is an on-going problem, the dxgmms2.sys BSOD indicates it is the Nvidia dedicated graphics drivers caused your system to crash.

    The best option is to completely remove the current Nvidia device driver using the widely available free DDU utility, then restart your PC and go to the Nvidia website to download and install a couple of slightly older version of the Nvidia device driver to try to find a version that is stable on your system.

    The BSOD (Blue Screen of Death) with the stop code SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E) that you encountered, specifically related to dxgmms2.sys, typically indicates an issue with the graphics driver or the graphics subsystem of your system. This file, dxgmms2.sys, is part of the DirectX graphics kernel and is responsible for handling graphics operations in Windows.

    Here are some potential causes and troubleshooting steps you can take:

    1. Graphics Driver Issues: Ensure that your graphics drivers are up to date. You can visit the NVIDIA website to download the latest drivers for your RTX 3050.
    2. Faulty Hardware: Sometimes, hardware issues can trigger BSODs. Ensure that your RAM and GPU are properly seated and functioning. Running hardware diagnostics may help identify any underlying issues.
    3. Windows Updates: Make sure your Windows 11 is fully updated, as updates can include important fixes for stability and performance.
    4. Corrupted System Files: Running the System File Checker (SFC) tool can help repair corrupted system files. You can do this by running sfc /scannow in the Command Prompt as an administrator.
    5. Event Viewer: Check the Event Viewer for any critical errors that occurred around the time of the BSOD. This can provide more insight into what might have caused the issue.

    Since your laptop worked fine after a restart, it might have been a temporary glitch. However, if the issue persists, consider following the steps above to troubleshoot further.
