Crash dump initialization failed, Event ID 46 [Fix]

The Pagefile acts as a virtual space where Windows can save files, and during the first boot, it is an important file to help Windows complete the setup. It’s also needed during boot to help manage memory requirements and ensure a smooth startup process for the operating system.

Fix Event ID 46, Crash dump initialization failed

There are two quick ways to eliminate the Crash dump initialization failed error which you may see in the Windows Event Viewer:

  1. Enable memory dump settings
  2. Generate memory dump file manually
  3. Rollback BIOS or UEFI Update

You can do this by booting your PC into Safe Mode using the Bootable media device and going into Advanced Recovery.

1] Enable Memory Dump Settings

First, you can try to change memory dump settings in Windows Settings. A Memory Dump takes all the information in your device’s working memory and creates a copy in your computer’s HDD.

When you enable memory dump settings, you allow your system to capture and store diagnostic information when a system crash or error occurs. So the information is saved in a memory dump file, which can be used to analyze the crash’s cause.

To get started with this, you can follow the below steps:

  • Press Windows Key + I to launch Settings.
  • Go to System > About.
  • Click on Advanced system settings under Device Specifications.

Advanced System Settings Memory

  • Next, click on the Advanced tab.
  • Now click on the Settings button under Startup and Recovery.

System Properties Memory Dump

  • Use the dropdown menu under Write debugging information to select complete memory dump.

Complete Memory Dump

  • Finally, click on OK to save the chances.

Once done, reboot your computer and check if you are still getting any issues with crash dump initialization when booting up.

2] Generate Memory Dump File Manually

Usually, the contents in your RAM are written to a paging file located on the same partition as your Windows. However, if the dump file is larger than 2GB, it will take a long time to respond. To deal with this, you can generate a memory dump file manually by following the below steps:

  • Press the Windows key + R to launch Run.
  • Type regedit and press Enter.
  • Now go to the following Registry path:
  • Next, right-click the empty area and select New > DWORD (32-bit) value.
  • Rename the new key file as NMICrashDump.
  • Then double-click the newly created key and set the value data to 1 from 0.

Generate Memory Dump File Registry

  • Finally, click OK and reboot your computer to see if it has fixed your issue.

3] Rollback BIOS or UEFI Update

Some users have also reported that rollbacking the motherboard firmware to its previous version can help. In this case, it’s a hardware issue caused by the firmware.

Check with your OEMs manual on how you can roll back the firmware.

What is the Event ID for a system crash?

The system crash is identified by an Event ID, a distinct numeric code that aids in organizing and monitoring particular occurrences within the Windows Event Log. Within Windows operating systems, the Event Log acts as a centralized storage where a range of events and actions taking place in the system, including application installations, security events, errors, warnings, and system crashes, are recorded.

How do I see crashes in Event Viewer?

Using Event Viewer, you can observe system failures by navigating to the System log in Windows Logs. This log encompasses important system occurrences, such as blue screen errors (BSODs) or system crashes. You can promptly detect and examine the crash incidents by filtering the log to display Critical and Error events.

TIP: You can analyze Windows Memory Dump .dmp files with WhoCrashed.
