Key notes

  • If you’re installing drivers manually, download the driver files from the Official manufacturer's website.
  • Avoid overloading your PC with complex tasks to prevent it from experiencing the BSOD.
  • You should only consider reinstalling Windows after all troubleshooting efforts have proven futile.

Dxgmms1.sys is a Microsoft DirectX Graphics MMS system driver file, but sometimes, this harmless file can trigger a BSoD error. In this article, we will explain its functions and provide the necessary steps to help you disable or fix it.

What is dxgmms1.sys, and why does it cause BSoD?

As we’ve mentioned above, dxgmms1.sys is a DirectX-related file that Windows deploy to manage the graphics of your PC. The file is completely safe and isn’t a threat to your computer.

However, apparently out of the blue, the system crashes into a BSoD pointing directly at dxmms1.sys. Here are some potential reasons:

  • Outdated or corrupted graphics driver – BSoDs and this particular dxgmms1.sys file crashes are mostly due to graphics driver problems. Updating the graphics driver will fix the problem.
  • Graphics card conflict – If you have a discrete graphics card, it may conflict with the existing Intel integrated GPU and crash the system. Disabling the integrated GPU will solve the issue.
  • System file corruption – System file corruption is one of the other possible reasons, and some dedicated scans might fix the problem quickly.

Now that we know what causes the problems with dxgmms1.sys, let’s try to fix o disable it.
