Update Your Graphics Drivers

Keeping your drivers up-to-date is crucial for the smooth functioning of your computer’s hardware and software. Outdated graphics drivers can often lead to system errors like the dxgmms2.sys error.

  3. Select ‘Search automatically for updated driver software’ and follow the on-screen instructions.

Updating your graphics drivers can resolve compatibility issues and fix bugs that might be causing the dxgmms2.sys error. The downside is that sometimes new drivers can introduce their own set of bugs, but these cases are relatively rare.

Run Windows Update

Windows Update not only provides fresh features but also delivers crucial bug fixes and security patches that could resolve the dxgmms2.sys error.


  1. Click on the Start menu and go to ‘Settings’.
  2. In the Settings menu, select ‘Update & Security’.
  3. Click on ‘Windows Update’ and then ‘Check for updates’. If updates are available, install them.

This method is generally beneficial as it ensures your system is up to date with the latest patches that can prevent or fix the dxgmms2.sys error. However, on certain occasions, a new update might conflict with existing software on your system.

Check for Hardware Issues

Faulty or incompatible hardware can sometimes cause system errors, so it’s essential to check if your hardware is functioning correctly.


  1. Shutdown your computer and unplug it from the power source.
  2. If comfortable, open your PC case and check for any loose connections.
  3. Make sure all components are seated correctly and that there’s no visible damage.
  4. If you’ve recently added new hardware, remove it to see if the error resolves.

Checking for hardware issues can be a free and effective way to resolve the dxgmms2.sys error. On the flip side, it may require advanced knowledge to diagnose hardware problems safely.

Perform a Disk Check

Corrupted files on your hard drive can lead to various issues, including the dxgmms2.sys error. Running a disk check can help spot and repair these issues.


  1. Press the Windows key and type ‘cmd’.
  2. Right-click on ‘Command Prompt’ and select ‘Run as administrator’.
  3. Type chkdsk /f and press Enter. Agree to schedule the check at the next system reboot by typing ‘Y’ when prompted.
  4. Restart your PC to let the disk check run.

A disk check can efficiently resolve issues caused by file corruption that might be causing the dxgmms2.sys error. However, in rare cases, it might incorrectly mark some files as corrupt and quarantine them.

Use the Windows Memory Diagnostic Tool

Defective RAM could be the root of the dxgmms2.sys error. Windows has a built-in tool to check for memory problems.


  1. Press the Windows key and type ‘Windows Memory Diagnostic’, and open it.
  2. Click on ‘Restart now and check for problems’. Your computer will reboot and the tool will check your RAM.

This tool can help determine if memory issues are at play and is a straightforward approach. If it finds a problem, you may need to replace your RAM, which is an additional cost.

Revert Recent Changes

If you started seeing the dxgmms2.sys error after installing new software or hardware, reversing those changes could solve the problem.


  1. Uninstall any recently added programs by going to ‘Settings’ > ‘Apps’ > ‘Apps & features’.
  2. If you installed new hardware, power down your PC, remove the hardware, and restart your computer.

Undoing recent changes can resolve the dxgmms2.sys error if those changes were the cause. However, you may lose the benefits of the new software or hardware.

System Restore

If you have a system restore point set up before the error started occurring, you can revert your system back to that configuration.


  1. Search for ‘Create a restore point’ in the Start menu and select it.
  2. Go to the ‘System Protection’ tab and click ‘System Restore’.
  3. Follow the on-screen instructions to select a restore point and restore your system.

System Restore can effectively undo recent system changes that may have caused the dxgmms2.sys error. The downside is that you may lose any data or programs installed after the restore point.

Reset Windows 11

As a last resort, resetting Windows 11 can refresh your system files and potentially fix the dxgmms2.sys error.


  1. Go to ‘Settings’ > ‘Update & Security’ > ‘Recovery’.
  2. Under ‘Reset this PC’, click ‘Get started’.
  3. Choose to keep or remove your files and follow the prompts to reset your PC.

Resetting Windows 11 can resolve stubborn system errors but at the cost of reinstalling all your software. It’s a drastic step but also a clean slate.
