This article serves as a comprehensive guide to analyzing BSOD dump files on Windows systems.
Configuring Dump Files in Windows 10
To configure dump files in Windows 10, open the Control Panel and select System. Click on Advanced System Settings and under the Advanced tab, select Settings under Startup and Recovery. Here you can configure the dump file settings including the type of dump file, where it’s saved, and whether the system should automatically restart after a BSOD. By default, Windows 10 is set to create a small minidump file which includes basic information about the crash. To analyze the dump file, you can use a tool like BlueScreenView which will display the error code, parameters, and other relevant information about the crash. With this information, you can try to determine the root cause of the problem and search for solutions online. Remember to refresh the view in BlueScreenView to see the latest screen crash reports.
Understanding Minidump Files and Their Importance in Diagnosing BSOD
When your computer encounters a Blue Screen of Death (BSOD), a minidump file is created with information about the crash. These minidump files are crucial in diagnosing and troubleshooting the root cause of the problem.
To analyze the minidump files, you can use a variety of utilities such as WinCrashReport, AppCrashView, and WhatIsHang. These tools provide information like the crash time, error codes, and parameters that can help identify the cause of the crash.
It’s important to note that minidump files only contain a portion of the memory dumps, so they may not provide a complete picture of what happened during the crash. However, they are still useful in identifying the problem and finding a solution.
By analyzing the minidump files, users can get a better understanding of the issue and determine whether it’s caused by hardware or software. Armed with this knowledge, they can take the necessary steps to fix the problem and prevent future crashes.
Using BlueScreenView to Analyze BSOD Crashes
Using BlueScreenView is a great way to analyze BSOD crashes. This software is free to use and available on Nir Sofer’s website. Once downloaded, open it and load your blue screen dump files. From there, you can view your crash information, including the error code, crash time, and description of the error. You can also use BlueScreenView to view properties of the drivers that caused the crash. To make the process easier, use the Auto Size Columns and Tab-Delimited features. With BlueScreenView, anyone can quickly and easily analyze BSOD crashes without having to search through physical memory or dmp files.

# Define the path to the Windows BSOD dump file
dump_file_path = r'C:WindowsMinidump 8182021-12345-01.dmp'
# Create a temporary directory to store extracted information
temp_dir = tempfile.mkdtemp()
# Extract the basic information from the dump file and store it in a text file
os.system(f'dumpchk.exe -y "C:symbols" "{dump_file_path}" > "{temp_dir}basic_info.txt"')
# Extract the stack trace from the dump file and store it in a text file
os.system(f'dumpchk.exe -y "C:symbols" -v "{dump_file_path}" > "{temp_dir}stack_trace.txt"')
# Extract the process list from the dump file and store it in a text file
os.system(f'dumpchk.exe -y "C:symbols" -l "{dump_file_path}" > "{temp_dir}process_list.txt"')
# Print the extracted information to the console
with open(f'{temp_dir}basic_info.txt', 'r') as f:
print(f.read())
with open(f'{temp_dir}stack_trace.txt', 'r') as f:
print(f.read())
with open(f'{temp_dir}process_list.txt', 'r') as f:
print(f.read())
# Delete the temporary directory
os.rmdir(temp_dir)
Note that this code uses the `dumpchk.exe` utility provided by Microsoft to analyze the Windows BSOD dump file. You will need to have this utility installed on your system for the code to work. Additionally, this code only extracts a few basic pieces of information from the dump file. You may need to modify it to extract more information depending on your requirements.
Viewing Crashes and Drivers Information Columns

| Crash Time | The date and time when the crash occurred |
| Bug Check Code | The hexadecimal code representing the type of error that caused the crash |
| Bug Check String | A description of the error that caused the crash |
| Parameter 1-4 | Additional information about the error that caused the crash |
| Driver | The name of the driver that caused the crash |
| Driver Address | The memory address where the driver was loaded |
| Driver Module | The name of the module that contains the driver |

Translating BlueScreenView to Other Languages
- Download and install the latest version of BlueScreenView from Nirsoft website.
- Open the BlueScreenView software.
- Click on the “Options” menu and select “Advanced Options”.
- Click on the “Languages” tab.
- Select the language you want to translate BlueScreenView into from the drop-down menu.
- Click on the “Translate” button.
- Translate the strings in the “Language Translation” window.
- Save the translated language file with a unique name, for example, “bluescreenview_french.lng”.
- Copy the translated language file to the BlueScreenView folder.
- Restart BlueScreenView to see the translated interface.
Troubleshooting Hardware Errors Causing BSOD
When troubleshooting hardware errors causing BSOD, it’s important to analyze the Windows BSOD dump file for clues. First, access the dump file and determine the stop error code. Use a tool like WinCrashReport or AppCrashView to view the application crash information and report. Look for any device driver issues or errors related to physical or screen memory dumps. Check the file version and properties of any potentially problematic applications. Use WhatIsHang to analyze any application that may be causing the BSOD. If you’re still unsure, try searching for the error code or message on Google or seek assistance from a knowledgeable source. Remember to keep your utilities and versions up to date to avoid future issues.
