How To Fix Application Has Been Blocked From Accessing Graphics Hardware In Windows 10

Application Has Been Blocked From Accessing Graphics Hardware

1. Reinstall The Driver For Intel Graphics Card

In most cases, this error occurs because something has gone wrong with the driver of your Intel graphics card. Therefore, if you want to resolve this problem, reinstalling the driver of your in-chip graphics card is the best choice.

Firstly, you need to visit Intel’s Download Center to download the latest version of the Intel Graphics Driver for your Windows 10 computer.

Then, there are two choices you can select from download installable file (.exe), or download a compressed file (.zip).

1.A. Use Installable File

If you choose and download the installable file (.exe), press Windows + X, then select “Device Manager” from the context menu (or press M to open instead).

Next, expand “Display adapters” and right-click on your in-chip graphics card. In my case, it’s “Intel® HD Graphics 4600“.

In the next step, choose the “Uninstall” option and tick the “Delete the driver software for this device” checkbox to remove the driver out of your Windows PC.

Uninstall Intel HD Graphics driver

Next, click on the installable file you have downloaded before and start to set up a new driver for your built-in-chip Intel graphics card.

If required, reboot your computer after the installation process is complete!

1.B. Use Compressed File

If you select and download the compressed file (.zip), extract it to a particular folder.

In the next step, press Windows + X and then hit the M key to open Device Manager.

Expand the “Display adapters” option and right-click on your Intel graphics card and then select the “Update Driver Software…” option.

Next, choose the “Browse my computer for driver software” option.

Update driver software

In the next step, select the folder you have extracted that contains the driver files for the Intel graphics card. Then click on the “Next” button to install the driver.

Once the card driver has been installed successfully, you can restart your Windows PC.

2. Use Windows Registry Editor

If the method above doesn’t work, you can try using Windows Registry Editor to adjust the value of TdrDela entry, which represents Timeout Detection and Recovery.

Increasing this value will increase the processing time of your graphics card, which helps to get rid of the Application Has Been Blocked From Accessing Graphics Hardware error in Windows 10.

To adjust this value, press Windows + R, type: regedit and then press Enter to open Windows Registry Editor.

In the Registry Editor, look at the left panel and open the following path:

HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control -> GraphicsDrivers

Next, create a new DWORD (32-bit) entry named TdrDelay. Then double-click on it and set the value to be 8.

Click on the “OK” button to save the change. After that, close Registry Editor and restart your computer.

Below is a short windows registry tutorial:

3. Use System File Checker And DISM Tools

In several cases, corrupted or missing system files that are related to your graphics card can lead to this error.

To resolve this, you can use the System File Checker and DISM tools to scan for corrupted/missing files and replace them if available.

To get started, press the Windows + X combination and then choose the “Command Prompt (Admin)” option.

In the Command Prompt window, type: sfc /scannow and hit the Enter key to execute the command.

Command Prompt: sfc /scannow command

It will take a while to search for corrupted/missing files and replace them. So just wait for the process to complete and be patient!

After the System File Checker tool has done its job, perform the following command to run the DISM tool.

  • DISM.exe /Online /Cleanup-image /Scanhealth

After the scan process is complete, use this command to repair corrupted files:

  • DISM.exe /Online /Cleanup-image /Restorehealth

Once it’s done, reboot your Windows computer and check again whether the error is fixed or not.

In case you have tried all methods above and the error persists, I would recommend using Windows System Restore to roll back your Windows OS to a previous point when it’s still in the good state.

Otherwise, you can try to reset your Windows 10 computer but keep the personal files. However, if you choose to reset your computer, all installed apps will be removed and you’ll have to download and install them again.
