Utilize System File Checker and DISM

To fix the issue of an application being blocked from accessing graphics, you can utilize System File Checker (SFC) and Deployment Image Servicing and Management (DISM). These tools can help repair any corrupted system files that may be causing the problem.

1. Use System File Checker (SFC) to scan and repair corrupted system files: Open Command Prompt as an administrator by typing “cmd” in the Windows search bar, right-clicking on Command Prompt, and selecting “Run as administrator.” Then, type “sfc /scannow” and press Enter. This will initiate the scanning and repair process.

2. Utilize DISM to repair the Windows system image: In the same Command Prompt window, type “DISM /Online /Cleanup-Image /RestoreHealth” and press Enter. This will instruct DISM to check for and repair any issues with the Windows system image.

After running both SFC and DISM, restart your computer to see if the application is now able to access graphics without being blocked. If the issue persists, you may need to further troubleshoot or seek additional support.

By using these built-in Windows tools, you can effectively address the issue of applications being blocked from accessing graphics on your Windows 10 system.

Troubleshoot Hardware Devices

    • Locate the device in question and right-click on it, then select Update Driver
    • Follow the on-screen instructions to search for and install the latest driver updates
  • Ensure the device is properly connected
    • If the device is an external component, such as a graphics card, ensure it is securely connected to the motherboard
    • Check for any loose or damaged cables and connections
  • Check for hardware conflicts
    • Open Device Manager and look for any devices with a yellow exclamation mark, indicating a conflict
    • Right-click on the conflicting device and select Properties to view the error message and troubleshoot accordingly

Modify Registry and TDR Settings

Windows Registry Editor

To modify the Windows Registry and TDR settings to fix the issue of an application being blocked from accessing graphics, follow these steps:

1. Press the Windows key + R to open the Run dialog box.
2. Type “regedit” and press Enter to open the Windows Registry Editor.
3. Navigate to “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers” in the Registry Editor.
4. Right-click on an empty space in the right-hand pane and select “New > DWORD (32-bit) Value“.
5. Name the new value “TdrDelay” and set its value data to “8“.
6. Create another DWORD (32-bit) Value and name it “TdrDdiDelay“, setting its value data to “8” as well.
7. Close the Registry Editor and restart your computer for the changes to take effect.

These steps will modify the TDR settings in the Windows Registry, potentially allowing the application to access graphics without being blocked. It’s important to be cautious when modifying the Windows Registry, as incorrect changes can have significant consequences for your operating system.

If you’re still experiencing issues after modifying the registry, it may be helpful to update your graphics card drivers or seek further assistance from customer support or online forums. Always ensure that you’re downloading drivers or tools from a reputable source to avoid malware or other potential security risks.
