At times it may be necessary to manually force a system crash in Windows to capture an event that is difficult to reproduce (eg. random flicker). The system crash will save the events to a dump file which can be used for debugging purposes. Please follow the steps below to force a system crash:
1. First we will need to change the Write debugging information setting to "Complete memory dump". In Windows, go to Control Panel > System and Security > System. Click Advanced system settings. Under Startup and Recovery, click Settings. Under the Write debugging information drop down box, please select "Complete memory dump". Then plress the OK button.
2. If you are using a PS/2 keyboard, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\i8042prt\Parameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.
3. If you are using a USB keyboard, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\kbdhid\Parameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.
4. Reboot your PC
5. Now your PC is ready. After you reproduce the issue, immediately trigger a crash by holding down the rightmost CTRL key, and press the SCROLL LOCK key twice. The dump file will be located at c:\Windows\MEMORY.DMP
If you are asked by an NVIDIA Customer Care agent for the full memory dump file, you will first need to upload it to a file sharing site such as Google Drive, Microsoft Onedrive, etc.. A full memory dump file will typically be at least 1GB in size although you can greatly reduce the file size by compressing the file using the built in Windows zip function or a 3rd party zip utility. Once you have zipped and uploaded the file to a file sharing site, please share the link to download the file with the NVIDIA support agent.
