Title: How to Fix DaVinci Resolve Not Opening or Keeps Crashing on Startup:

Welcome to our friendly guide on how to resolve the common issue of DaVinci Resolve not opening or continuously crashing on startup. We understand how frustrating it can be, but fear not! By following these simple steps, you'll be back to editing your videos in no time.

DaVinci Resolve is a powerful video editing software that offers professional-grade features for both amateur and professional video editors. However, like any software, it can encounter issues that prevent it from functioning properly. One of the most common problems users face is DaVinci Resolve not opening or crashing on startup. This can be caused by a variety of factors, from outdated graphics drivers to insufficient virtual memory.

In this blog post, we'll walk you through each step to help you troubleshoot and fix the issue. So, let's dive in!

1. Update Your Graphics Drivers:

The first step in resolving the issue of DaVinci Resolve not opening or crashing on startup is to ensure that your graphics drivers are up to date. Outdated drivers can often cause conflicts and instability within the software. To update your graphics drivers, visit the website of your GPU manufacturer (NVIDIA, AMD, etc.) and download the latest drivers for your specific model.

Keep in mind that different GPU manufacturers have different methods for updating drivers, so make sure to follow the instructions provided on their websites. Once you have updated your graphics drivers, restart your computer and try opening DaVinci Resolve again.

2. Use a Dedicated GPU Instead of Integrated One:

If you're currently using an integrated GPU (iGPU), consider switching to a dedicated graphics card if possible. DaVinci Resolve heavily relies on GPU performance, and using a dedicated GPU can significantly improve stability and overall performance. Integrated GPUs may not have enough processing power to handle the demands of the software, leading to crashes on startup.

If you have a dedicated GPU installed on your system, make sure it is properly connected and recognized by your computer. You may need to adjust some settings in your computer's BIOS to ensure that the dedicated GPU is being utilized instead of the integrated graphics. Consult your motherboard's manual or search online for instructions on accessing and enabling this setting.

3. Increase Virtual Memory:

Insufficient virtual memory can also lead to crashes in DaVinci Resolve. Virtual memory, also known as the page file, is a portion of your hard drive that is used as temporary storage when your computer's physical RAM is full. To address this, you can increase the allocated virtual memory on your computer.

To do this on a Windows system, go to "System Properties" by right-clicking on "This PC" or "My Computer" and selecting "Properties." In the System Properties window, click on the "Advanced system settings" link on the left-hand side. This will open the System Properties dialog box.

In the System Properties dialog box, go to the "Advanced" tab and click on the "Settings" button under the Performance section. This will open the Performance Options dialog box. In the Performance Options dialog box, go to the "Advanced" tab and click on the "Change" button under the Virtual memory section.

Here, you can adjust the size of the virtual memory manually or select the option for automatic management. If you choose to adjust the size manually, make sure to allocate enough space to accommodate the demands of DaVinci Resolve. Once you have made the changes, click on the "OK" button to save the settings.

On a macOS system, the process is slightly different. Go to the Apple menu and select "System Preferences." In the System Preferences window, click on the "Security & Privacy" icon. In the Security & Privacy window, go to the "Privacy" tab and click on the "Full Disk Access" option on the left-hand side.

In the Full Disk Access settings, click on the lock icon at the bottom left corner of the window and enter your administrator password to make changes. Then, click on the "+" button and navigate to the Applications folder. Select the DaVinci Resolve application and click on the "Open" button to grant it full disk access.

4. Enable IGPU Multi-Monitor:

Enabling IGPU Multi-Monitor in your computer's BIOS settings can sometimes help with stability issues related to DaVinci Resolve's hardware acceleration features. IGPU Multi-Monitor allows the integrated GPU to work in conjunction with a dedicated GPU, providing additional processing power and reducing the load on the dedicated GPU.

To enable IGPU Multi-Monitor, you'll need to access your computer's BIOS settings. The process for accessing the BIOS can vary depending on your motherboard manufacturer. Consult your motherboard's manual or search online for instructions on accessing and enabling this setting.

Once you have accessed the BIOS settings, look for an option related to IGPU Multi-Monitor or integrated graphics. Enable this option, save the changes, and exit the BIOS. Restart your computer and try opening DaVinci Resolve again to see if the issue has been resolved.

5. Reset DaVinci Resolve Preferences:

    If the above steps didn't resolve the problem, resetting DaVinci Resolve preferences might do the trick. Preferences are the settings and configurations that DaVinci Resolve saves to customize your editing environment. Sometimes, corrupted or misconfigured preferences can cause issues with the software.

    To reset DaVinci Resolve preferences, you'll need to locate the preferences folder on your computer. On a Windows system, the preferences folder is typically located at C:\Users\[Username]\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support. On a macOS system, it can be found at /Library/Application Support/Blackmagic Design/DaVinci Resolve/Support.

    Once you have located the preferences folder, you can either delete it or rename it to something like "Preferences_old" to keep a backup. Deleting or renaming the preferences folder will reset all preferences to their default values. Restart DaVinci Resolve and check if the issue has been resolved.

    6. Change the Priority of the Process:

    Adjusting the priority of the DaVinci Resolve process can sometimes help improve its stability. Process priority determines how much CPU time and resources are allocated to a specific process. By giving DaVinci Resolve a higher priority, you ensure that it gets the necessary resources to run smoothly.

    To change the priority of the DaVinci Resolve process, open the Task Manager by pressing Ctrl + Shift + Esc on your keyboard. In the Task Manager window, go to the "Details" tab. Scroll through the list of processes until you find "DaVinciResolve.exe." Right-click on it and hover over the "Set Priority" option.

    From the submenu, choose a higher priority option such as "High" or "Realtime." Keep in mind that setting the priority to "Realtime" can cause other processes on your computer to become unresponsive, so use it with caution. After changing the priority, close the Task Manager and try opening DaVinci Resolve again.

    7. Change the Input Video File Location or Convert it to MOV:

    If DaVinci Resolve is crashing upon importing or working with a specific video file, it's possible that the file location or format is causing conflicts within the software. To troubleshoot this issue, try moving the video file to a different location on your computer or convert it to a different format like MOV.

    Sometimes, file locations that contain special characters or long file paths can cause issues with DaVinci Resolve. By moving the file to a different location with a simpler file path, you eliminate potential conflicts. Similarly, certain video file formats may not be fully supported by DaVinci Resolve, causing crashes during editing or playback. Converting the file to a different format can resolve this issue.

    There are many video converter tools available online that allow you to convert video files to different formats. Choose a reputable converter, select the desired output format (such as MOV), and convert the problematic video file. Once the conversion is complete, try importing and editing the converted file in DaVinci Resolve to see if the issue persists.

    8. Update or Clean Install DaVinci Resolve:

    Lastly, make sure you have installed the latest version of DaVinci Resolve. Updating to the most recent release can often fix bugs and compatibility issues that may be causing the software to crash on startup. Visit the official DaVinci Resolve website and download the latest version for your operating system.

    If updating DaVinci Resolve doesn't resolve the issue, consider performing a clean installation. A clean installation involves uninstalling the current version of DaVinci Resolve and then installing the latest version from scratch. This ensures that any corrupted or misconfigured files from the previous installation are completely removed.

    To perform a clean installation, first, uninstall DaVinci Resolve from your computer. On a Windows system, go to the Control Panel and select "Uninstall a program" or "Programs and Features." Find DaVinci Resolve in the list of installed programs, right-click on it, and choose "Uninstall." Follow the on-screen prompts to complete the uninstallation process.

    On a macOS system, locate the DaVinci Resolve application in the Applications folder. Drag the application to the Trash or right-click on it and select "Move to Trash." Then, empty the Trash to remove the application completely.

    After uninstalling DaVinci Resolve, restart your computer. Download the latest version of DaVinci Resolve from the official website and install it following the provided instructions. Once the installation is complete, try opening DaVinci Resolve to see if the issue has been resolved.

    By following these friendly guidelines step-by-step, you should be able to resolve the issue of DaVinci Resolve not opening or continuously crashing on startup. Remember to update your graphics drivers, consider using a dedicated GPU, increase virtual memory, enable IGPU Multi-Monitor if applicable, reset preferences, change process priority, check input video file location/format, and update or perform a clean install of DaVinci Resolve.


    Remember that troubleshooting software issues can sometimes require a bit of trial and error. If one method doesn't work, don't get discouraged. Move on to the next step and continue until you find a solution that works for you. If all else fails, don't hesitate to reach out to the DaVinci Resolve community or support team for further assistance.
