Hello!

I'm having random Windows crashes and I honestly don't know where to look anymore. They happen completely random. Sometimes the computer is just on idle, nothing open and it simply restarts, and sometimes it happens while I'm gaming or working.

No bluescreen, just auto shutdown and restart.

The dmp file show error in ntoskrnl.exe+6b60e9 and rtwlanu.sys+48304 every single restart.

I can provide more info if needed, I wasn't able to attach the dmp file here

Thanks in advance.

    Hi,

    According to your information, the crash is due to a wireless network driver. We need to investigate the problem further, if possible.

    If it is a laptop or desktop, if possible, could you provide the laptop model or your desktop configuration?

    Access the c:\windows\minidump folder, copy the files to your desktop, then upload them to OneDrive or Google Drive and post the link here for analysis.

    Thanks

    It sounds like you're experiencing random crashes in Windows 11 that are linked to specific drivers and system files. The errors you mentioned, ntoskrnl.exe and rtwlanu.sys, suggest that the issue may be related to the kernel and a network driver, respectively.

    Here are some steps you can take to troubleshoot the issue:

    1. Update Drivers: Since rtwlanu.sys is related to the Realtek wireless LAN driver, ensure that you have the latest version of this driver installed. You can check the manufacturer's website for updates or use Windows Update to find the latest drivers.
    2. Check for Windows Updates: Make sure your Windows 11 is up to date. Microsoft often releases patches that can resolve stability issues.
    3. Memory Dump Analysis: If you have access to the memory dump files, you can analyze them using debugging tools like WinDbg. This can provide more insight into what might be causing the crashes. Refer to the documentation on how to set up and analyze crash dumps for more detailed guidance.
    4. Hardware Check: Random crashes can also be caused by hardware issues. Check your RAM and hard drive for errors. You can use tools like Windows Memory Diagnostic for RAM and CHKDSK for your hard drive.
    5. System Restore: If the crashes started recently, consider using System Restore to revert your system to a previous state when it was stable.
    6. Event Viewer: Check the Windows Event Viewer for any critical errors or warnings around the time of the crashes. This can provide additional context on what might be causing the issue.

    If the problem persists after trying these steps, you may want to consider reaching out to Microsoft support or a professional technician for further assistance.
