How to Read Dump Files
Co-authored by Luigi Oppido
Updated: October 7, 2019

This wikiHow teaches you how to analyze your Windows computer’s dump files after a crash. Dump files, which are automatically created by Windows after your computer crashes, display a list of programs that were running before the crash; this can help you determine which programs are responsible for the crash. If you’re anticipating another crash or you want to test a program, you can use a free program called BlueScreenView to analyze your dump files. You can also use the free Windows 10 Drivers Kit to open dump files from a past crash.

Part 1 of 2:
Reading with BlueScreenView

Open Start . Click the Windows logo in the bottom-left corner of the screen.

2
Type in view advanced system settings. This will search your computer for the Advanced System Settings section of Control Panel.

3
Click View advanced system settings. It’s a computer monitor with a checkmark icon at the top of the Start menu. Doing so opens the Advanced System Settings window.
4
Click the Advanced tab. You’ll see this at the top of the window.
You may first have to click the computer monitor-shaped icon that appears at the bottom of the screen to open the Advanced System Settings window.
5
Click Settings. It’s below the “Startup and Recovery” heading near the bottom of the page. Doing this will open a separate window.
6
Click the “Write debugging information” drop-down box. You’ll find this box in the middle of the separate window. Clicking it prompts a drop-down menu.

Click Small memory dump. It’s in the drop-down menu. This option makes future memory dumps readable with a simple file explorer such as BlueScreenView.

A memory dump file is a file that’s taken from RAM. RAM has a number of allocation tables—or buckets—inside. A memory dump file is an entire download of whatever was inside that file when a catastrophic failure happened, and it goes into a log so an engineer or a software professional can look at it and see where the conflict happened.

8
Click OK. It’s at the bottom of the window. This will close the window and return you to the Advanced System Settings window.
9
Click OK. Doing so saves your changes and closes the Advanced System Settings window.
10
Open the BlueScreenView page. Go to https://www.nirsoft.net/utils/blue_screen_view.html in your browser. BlueScreenView is a program that finds and analyzes dump files for you, making it easy to see which programs were running directly before a crash.
11
Download BlueScreenView. Scroll down and click the Download BlueScreenView with full install/uninstall support link that’s near the middle of the page.
12
Open the BlueScreenView setup file. Double-click the bluescreenview_setup file in your computer’s “Downloads” location.

Review your dump files. BlueScreenView has a top pane and a bottom pane; you’ll see the dump file(s) listed in the top pane, while the programs that were recorded by the currently selected dump file will appear in the bottom pane.
You can select a dump file by clicking it in the top pane.
At least one of the programs that were recorded by the dump file is most likely responsible for the crash.

Add a symbol path. The symbol path tells the Windows Debugger which information to display:[1]

Type in SRV*C:\SymCache*http://msdl.microsoft.com/download/symbols

Tips
BlueScreenView is perfect for testing different programs (e.g., opening a program and waiting to see if your computer crashes), as it can be opened quickly and takes only a few seconds to install.
Warnings
Computer crashes—especially ones of the blue screen of death variety—can be caused by anything from a malfunctioning app to a broken processor. As such, being able to read the dump files doesn’t necessarily guarantee that you’ll be able to diagnose your computer’s crashing.
