II. How to fix Dxgmms2.sys

Here are a few ways to troubleshoot Dxgmms2.sys. You should try the methods sequentially to see which works for your system.

1. Hardware test

You should start by making sure that hardware like RAM, GPU, and hard drive are working properly.

Try removing the RAM, cleaning the RAM pins and the communication port to remove dirt. Then plug it back in to see if the RAM is faulty. You should also do the same for the GPU, remove and clean its interface.

For the hard drive, use third-party software to monitor and check its health.

2. Update Driver

Outdated or corrupted drivers can also be the cause of the computer configuration not being able to operate at maximum efficiency. Thuthuatphanmem.vn recommends updating the latest driver for your GPU.

To update drivers in general, you can use third-party software to automatically detect and replace old, damaged drivers. 

For the GPU driver, visit NVIDIA or AMD's website to download the driver, depending on the type of video card you use.

3. Run the DirectX . diagnostic tool

DirectX is an API that enhances your multimedia experience on your computer. It has a built-in diagnostic tool in Windows 10 to display all current information about the graphics hardware as well as related software.

Step 1: Press the Windows + R combination to open the Run dialog box, then type dxdiag and Enter.

Step 2: When the tool launches, switch to the Display tab and check if the 3 features in DirectX (DirectX Features) have been enabled (Enabled) or not?

If you see this feature as Disabled, then you must reinstall DirectX on your PC. Download DirectX and install it.

4. Reset BIOS

Misconfigured BIOS can also lead to blue screen on PC. Therefore, if the above doesn't solve the problem, try reinstalling your entire BIOS settings.

First, you need to access your computer's BIOS using one of the ways in this article.

Then, go to 'Reset BIOS', 'Load Optimized Defaults' or 'Restore Defaults' (depending on different BIOS). Usually you will find it on the Save & Exit page or the Security page.

Select Yes in the question to reset the settings.

III. Increase tdrdelay time

TdrDelay is the GPU delay before processing scheduled tasks. This value is in seconds and by default its value is 2. You can change this number through Registry Editor, here's how.

Before doing so, you should back up the Registry Editor, because any mistake in making changes to the Registry can affect system functionality.

Now, press the Windows + R combination to open the Run dialog box, then type regedit and press Enter.

Open the folder sequentially with the following path, or simply copy-paste it into the address bar:

Computer/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/GraphicsDrivers

Now right click on GraphicsDrivers in the left pane >> New >> DWORD (32-bit) Value.

Name this new DWORD TdrDelay.

Once created, double click on TdrDelay and set the Value Data to 10 and then OK. The system will need to reboot for the change to take effect.

Turn off hardware acceleration

The purpose of hardware acceleration is to provide better performance, while consuming less power. However, sometimes it causes Dxgmms2.sys blue screen. So you need to disable it and check if the problem is resolved or not?

To disable hardware acceleration, you need to launch Registry Editor again and access the path: Computer/HKEY_CURRENT_USER/SOFTWARE/Microsoft/Avalon.Graphics

Right click on the upper right area in the right pane >> New >> DWORD (32-bit) Value.

Now name the DWORD as DisableHWAcceleration.

Once the new key has been created, double click to open it, set the Value data to 1 and click OK.

Please restart the computer for the changes to take effect.
