Hello, I am Henry, I will help with this.

This is the initial output from WinDbg loading your minidump. The most crucial information for analysis is missing, which is the output of the !analyze -v command.

You've correctly loaded the dump file, and the debugger has identified it as a "Mini Kernel Dump File."

Here's what I know so far:

• OS: Windows 8.1 Kernel (likely Windows Server 2012 R2, given "Product: Server" and the build lab "winblue_ltsb")
• Architecture: x64
• Processors: 8
• System Uptime: 64 days (long uptime can sometimes contribute to issues due to resource exhaustion or accumulated errors, but isn't a direct cause itself)
• Debugger Ready: The debugger is loaded and symbols are being processed.
• Last instruction before crash: nt!KeBugCheckEx was called. The value in rcx (the first argument to KeBugCheckEx) is 000000000000000a. This means the Bug Check Code was 0xA (or IRQL_NOT_LESS_OR_EQUAL).

In the WinDbg command window (where you see kd>), type the following command and press Enter:

This command will perform an automated analysis of the dump file and provide:

The Bug Check Code (which we already suspect is 0xA).

• The Bug Check Parameters (Arg1, Arg2, Arg3, Arg4). For 0xA, these are:
  • Arg1: The memory address that was improperly referenced.
  • Arg2: The IRQL at the time of the fault.
  • Arg3: Type of access (0 = read, 1 = write).
  • Arg4: The instruction pointer (address of the instruction that referenced the bad memory).
• A Probably Caused By line, which often points to a specific driver file (e.g., some_driver.sys). This is extremely helpful.
• The Call Stack, showing the sequence of function calls that led to the crash.

Also you can consider these general troubleshooting steps for your server (if it's still unstable):

1. Recent Changes: Did this start happening after installing new software, updating drivers, or adding new hardware? If so, try rolling back those changes.
2. Driver Updates: Check for updated drivers for your main hardware components, especially network, storage, and graphics (if applicable to a server).
3. Windows Updates: Ensure your Windows Server 2012 R2 is fully updated.
4. Hardware Diagnostics: Run memory tests (like MemTest86+) and check hard drive health (e.g., chkdsk /f /r from a recovery console, or vendor-specific tools).
5. Event Viewer: Check the System and Application logs in Windows Event Viewer for any errors or warnings leading up to the BSOD times.

Hope this can provide the right direction for your troubleshooting.
