You are playing your favorite game in Windows and suddenly get an error message “Application is blocked from accessing the graphics hardware”. The same error can occur when running other software on your computer. What is the cause of this problem and how to fix it? This error usually occurs when you have incompatible display drivers installed on your device. However, there are several other reasons for this problem, which we will discuss in more detail. So, let’s start without further ado.

What causes this error?

The exact cause of the error is still unknown, but it is assumed that the problem is caused by the drivers. After a major operating system update, your graphics drivers may no longer be compatible with your version of Windows 10. This is especially true if you update your drivers manually rather than using the automatic update tool. Therefore, your graphics processing unit (GPU) gets stuck and does not respond to the graphics request sent by your system.

If your GPU does not respond within a given amount of time, Windows 10 aborts the attempt to start the application and displays the error message “The application cannot access the graphics hardware”. Another reason for this error message could be that there are too many visual effects or programs running in the background.

How to fix this error?

Windows 10 offers built-in tools to manage graphics card drivers, and you can use these to update your drivers with just a few clicks. Here’s how:

  3. Expand the “Display adapters” section.
  4. Right-click on your graphics card and select “Update Driver.”
  5. Choose the “Search automatically for updated driver software” option.
  6. Windows will now search for and install the latest drivers for your graphics card.
  7. Once the process is complete, restart your computer to ensure that the new drivers are properly installed.

Launch the application as an administrator 

In order to run an application as an administrator on Windows 10, there are a few steps that must be followed.

  1. First, open the start menu and locate the app that you want to run as an administrator.
  2. Right-click on the app and select “Run as Administrator” from the drop-down menu.
  3. If you are prompted by User Account Control, click “Yes” to allow the app to make changes to your device.
