Capturing a crash dump file from a Windows blue screen (BSOD)

Windows can be configured to log crashes from an application or a TDR as dump files. TDR stands for Timeout Detection and Recovery. This is a feature of Microsoft's Windows which attempts to detect if your PC has frozen and attempts to recover by reinitializing the driver and reset the GPU. If you see your monitor flicker briefly followed by a TDR error message "Display driver stopped responding and has recovered" on your taskbar, this means that the Windows operating system succesfully recovered.

If you experience repeated application crashes or TDRs, Windows dump files can be used to help identify the cause of the issue. An NVIDIA Customer Care support agent may ask you to provide a dump file from your PC to troubleshoot the problem.

Enabling crash dumps

Two registry files are available for download from the File Attachment section at the bottom to assist you in configuring Windows to automatically generate dumps files when an application or process crashes. These crash dump files are available in one of the two formats. Please choose the registry file according to the type of dump file you wish to share with an NVIDIA Customer Care agent.

Mini dump - This is the Windows setting by default. This is a very small file which does not contain a lot of information. Due to the small file size, it makes it easier to share with an NVIDIA Customer Care agent. If you are unable to upload large file sizes, you may choose this by downloading the file minidump.reg below and then double-click on the file to add the contents to your Windows registry.

Full dump - This format creates a file that can be quite large in size. Usually a full dump file will be approximately 1000MB+ in size although you can compress the file which greatly reduces the file size. Due to the much bigger size, you will need to upload the file to use a file sharing service to provide the file to an NVIDIA Customer Care agent. This format includes much more information that a mini dump file and therefore is much more useful in finding the root cause of a crash. Download the file fulldump.reg from the bottom of the page and open the file to merge its contents with your Windows registry if you have good internet speeds.

Once you selected the dump file type you wish to use and merged the registry key file (minidump.reg or fulldump.reg), proceed to reproduce your issue again. Once you have reproduced the application crash or TDR, follow the instructions below to locate the dump file:

1. Press the Windows key on your keyboard and the letter "R" at the same time to bring up the Run command 2. Type the following in the Open field: %LOCALAPPDATA%\CrashDumps 3. Press OK button 4. It should open up the default folder where Windows saves your crash logs. Look for dump file from the time of your crash and if there is one, provide the file to the NVIDIA Customer Care agent. Mini dump files are small and can be attached directly to the support incident. Full dump files are much bigger and need to be compressed first to reduce the file size before sharing with the NVIDIA Customer Care agent

1. Right-click over the full dump file you wish to compress 2. In the context pop-up menu, select Send to -> Compressed (zipped) folder 3. The compressed file will have the same name as file you selected.

Today there are a number of file sharing options available such as Google Drive, Microsoft OneDrive, Dropbox, etc.. Choose a file sharing service and upload the compressed dump file. Once the upload is completed, you may share the download link with the NVIDIA Customer Care agent. If you are sharing driver feedback, you may email the link to download the dump file to
