Application blocked access to graphics hardware - how to fix. Application blocked access to graphics hardware - how to fix Application wot blocked access to graphics hardware

This is a notification about the incorrect operation of the graphics subsystem of your computer in Windows 10. It appears in the notification center as a text message when you start or after a certain time of operation of a program related to graphic output (Photoshop, 3D max, Corel Draw, computer games).

Go to Windows 10 Action Center

Error message

After the notification is displayed, the application hangs or exits.

Causes

There is no definite reason. But most often the notification is caused by a hardware or software malfunction of the graphics subsystem:

drivers installed incorrectly;
The graphics settings in the application that caused the error conflict with the settings in the device driver management utility.
incorrectly configured and installed drivers;
drivers were not updated correctly;
as a result of overclocking the video card or exceeding the recommended temperature;
as a result of a lack of power on the video card (s);
as a result of obsolete components required to run the application.

How to fix it

Reinstall the driver on your graphics card (s) after a clean install. A clean install is an installation after complete removal through a special program from the manufacturer, for example, or a third-party utility.

Display Driver Uninstall Window

Lower the characteristics (bus frequency, memory frequency) of the video card using a special utility (usually included with the video card). Increase the amount of power supplied to your graphics card.

Changing the characteristics of a video card in the GPU Tweak utility

Verify that when working in applications does not exceed the allowable rate. This can be done using any tester, for example.

If the utility displays a message that the temperature is exceeded, clean the cooling system of the video card.

Update the following operating system components:

DirectX 12;
MS C ++ Redistributable 2015

Restore system settings and system files with the recommended parameters. To do this, the command line as administrator. In the window that opens, type Dism / Online / Cleanup-Image / RestoreHealth and press Enter. Wait for the end of the operation. Then on the same command line enter sfc / scannow and press Enter. Wait for the end of the operation.

The problem is highly dependent on the application that invokes it. If this application is a computer game, then probably on the forum of the store where you purchased it, someone has already encountered this problem and may have solved it.

Below is a table with the games in which the problem occurred and how to solve it.

On the Microsoft forum and on other services, users complain about an error stating that the application is blocked from accessing graphics hardware on Windows 10. At the same time, no one offers a single solution to the problem. Some users were helped by downloading a new version of the software, and some even reinstalling Windows 10 did not bring a positive result. Therefore, we propose to consider the main methods for solving this error.

Solutions to the problem

An error when an application is blocked from accessing graphics hardware can occur both when installing the game and when using it. As noted on the forums, this issue occurs in World of Warship, GTA SA, GTA V, FIFA17, Black Desert, and Dota 2. It may also occur in other games.

On different resources, the tips that helped users get rid of the problem are different. Therefore, we list them:

In Dota 2, disabling vertical sync helped to get rid of the error. Also, in some cases, the error stopped crashing when the number of frames per second was limited.
Updating the video driver. If you don't have up-to-date drivers, it's worth putting the software in compatibility mode. In some cases, users noted that they were helped by installing the driver in an automatic mode. This means that the system installed the driver itself, which it needed.
You should definitely check the video card on the FurMark benchmark. This is software for determining temperature indicators. The system may give an error due to high readings of the temperature sensor. A complete cleaning of the PC with the replacement of thermal paste will not hurt.
If your PC does not run modern games, and you started overclocking the system and encountered such a problem, you should stop all manipulations and return the factory settings in the BIOS.
We also recommend installing DirectX 12 and C ++ libraries. With these components in place, video games will work fine.

At the end of 2017, with the release of update 1607, many users of the Windows 10 operating system began to receive an error: "The application is blocked from accessing windows 10 graphics hardware."

It is still not known for sure whether this error is a consequence of the installation of this update, or whether the reason lies in something else, but it is worth noting that computers on which the installation of the 1607 update was not carried out at all (yes, it arose in several years before the release of the update).

Unfortunately, one hundred percent working methods of dealing with the problem have not yet appeared. There are many recommendations that we will present in this article, but it is impossible to guarantee that they will work in each specific case.

How to unlock access to graphics hardware on Windows 10

So, the error looks like a message in the notification center with the text "Application blocked access to graphics hardware", and below it is specifically indicated which game or program the error is associated with (for example, browser.exe, wot, bf1.exe or world of tanks).

It is worth noting (and in some way a warning) - before proceeding with troubleshooting, you should create a system restore point - for safety reasons.

The reason lies in the software drivers for the video card

1. Open the "Device Manager" (right-click on "My Computer" - then "Management").

And go to the "Video adapters" section and do the following:

Select your video card and call its properties by clicking the right mouse button.

In the window that opens, go to the "Driver" tab and click on the "Remove" button.

Then restart your computer - the system should automatically install the missing driver. Accordingly, it would be a mistake to hope that the version of the automatically installed driver will be up-to-date.
Therefore, you need to visit the official website of the video card developers, find the missing, and most importantly, the current driver and install it manually using the "Device Manager" or manually using the installer;
After the installation is complete, restart your computer again.

Alternatively, you can try using specialized software: for example, "DriverPack Solutions". This method is not included in the number of basic and effective recommendations, but, at times, it really fixes the problem that has arisen.

2. Using software tools to remove old / unused drivers and their residual traces.

For AMD, Intel and Nvidia products, Display Driver Uninstaller has proven itself well.

Removing drivers is carried out in "Safe Mode", so after downloading the necessary software (installation is not required), restart your computer and enter "Safe Mode" using the "Startup Options" section.

In the line "Select video driver" select one of the options - "AMD", "Intel" or "Nvidia";
Click on the "Delete and Restart" button;
Wait for the automatic uninstallation process to complete, create an additional restore point, save the logs and reboot the system.

The further principle of action is similar to the previous method.

The problem of accessing graphics hardware lies in corrupted system files

This (like the previous version) was proposed by the developers themselves on the official sites (including the Microsoft forum).

To check the integrity of system files, two commands "Dism / Online / Cleanup-Image / RestoreHealth" and "sfc / scannow" are used.

To run them, you need to open the Command Prompt as administrator and copy and execute the above commands one by one.

If these utilities find any errors, they will be corrected automatically.

Additional options

Above, we mentioned that some of the custom options are fantastic enough, but they also have a healthy grain.

The error only occurs when connecting a second monitor (or using a TV as a monitor).
The problem is in the game / application / program itself.
Driver installation pre-running in compatibility mode.
Power supply problem. Failure or lack of power in the power supply unit or failure of surge protectors and uninterruptible power supplies.

Finally

So, the considered error is quite difficult for "home treatment" and elimination, since it is not known for certain and exactly what the cause of its occurrence is hidden in.

Someone refers to the incorrect update with the number 1607, someone blames the hardware for everything.

Therefore, first of all, pay attention to the drivers of the graphic component of the computer, including try to leave the driver option to the operating system itself.

Some users of Windows 10, while running a program (more often gaming), may encounter a crash of this program, and the system message "The application is blocked from accessing graphics hardware." The reason for this dysfunction can be a number of hardware and software problems, which I will list in this material, as well as tell you what this error is, when it occurs, and how to fix the error "The application is blocked from accessing graphics hardware" on your PC.

Error text "The application is blocked from accessing graphics hardware" on the PC screen

"The application is blocked access to graphics hardware" - the essence and causes of dysfunction

In most cases, this error on Windows 10 and not only occurs during the operation of any modern gaming or test program (for example, 3DMark), which actively uses the processor and video card of the user's PC.

The reasons for the "Blocked access to graphics hardware" error can be as follows:

How to fix the error "The application is blocked from accessing graphics hardware"

Uninstall the current graphics card driver and install the system selected driver... Go to "Device Manager" (click on the "Start" button, in the search bar enter devmgmt.msc and press enter), find your video card driver there (the "Video adapters" tab), right-click on it, and select "Uninstall". Restart your computer, and then let the system find and install the required driver on its own (use the "Windows Update" functionality);
Install an older video driver for your graphics card... If the previous method did not help, look for an older driver for your video card on the website of the video card (or motherboard) manufacturer;
Change AMD Catalyst settings(if available on a PC). Go to AMD Catalyst, select the "Performance" tab, activate the "Enable Graphics OverDrive" option there, and lower the frequency of your video card just below the normal level (yellow area);
Engage the "Graphics OverDrive" function
Check the performance of your PC's memory sticks... Check them with testing programs of the "Memtest 86" level, or, removing one by one the memory strips, check the stability of the system without the removed strips (this will help to identify the problem memory strip). In some cases, the problem appeared when installing an additional memory strip from a manufacturer other than the base strip. Installing an identical, to the base, strap made it possible to get rid of the "Application blocked access to graphics hardware" on the user's PC;
Disable overclocking settings... If you have previously overclocked the system using special software, then I recommend returning the system settings to default.
Disable Vertical Sync in the settings of the game program;
Decrease the frequency of the GPU and memory by 5%... Download and install MSI Afterburner and then reduce the specified parameters to the required frequency;
Install AMD Catalyst stable version on your PC... If your computer has an AMD graphics card, install the stable version of AMD Catalyst on your PC (according to customer feedback, installing AMD Catalyst ™ 15.11 Beta Driver for Windows® on your computer helped resolve the graphics hardware access error).

Use the well-proven AMD Catalyst version

Conclusion

An effective solution to the problem "Access to graphics hardware is blocked for the application" is to change the video card driver to a more stable one, as well as to check the performance of the PC memory bars (incorrect operation of one of them was often the initiator of the problem I am considering). If that doesn't work, use the other tips above, this will fix the problem of blocking access to graphics hardware on your Windows 10.
