I. What is Dxgmms2.sys?

Dxgmms2.sys is an important file in Windows responsible for the computer's graphics rendering capabilities. If it can't handle the rendering, it will stop all computer operations and display a blue screen. Then the computer needs to be restarted to fix the problem.

Some causes of dxgmms2.sys error:

1. RAM, hard drive failure
2. Firmware is not compatible
3. Outdated, corrupted drivers
4. Unable to respond to hardware accelerator
5. BIOS is corrupted

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Outdated or corrupted drivers can also be the cause of the computer configuration not being able to operate at maximum efficiency.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.

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.
