Fix #2: Disable the Hardware Acceleration Feature
Like third-party PC repair tools, your Windows computer has a feature that can be used to optimize and maximize its performance. It’s called the hardware acceleration feature.
While handy at times, this feature can trigger errors, including the dxgmms2.sys BSOD. So, you can try to disable it and check if it’s causing the problem.
To disable hardware acceleration, follow these steps:
- Press the Windows + R keys simultaneously to launch the Run dialog box.
- Into the text field, input regedit and hit OK.
- Next, navigate to HKEY_CURRENT_USER > Software > Microsoft > Avalon.Graphics.
- Locate DisableAcceleration and double-click on it. If you can’t find this feature, create one by right-click on any blank area on the right pane. Select New and click DWORD (32-bit) Value. Rename it to DisableHWAcceleration.
- Set the value to 1. This will disable the feature.
- Hit OK to save the changes.
- Restart your computer and check if the BSOD error still shows.
Fix #3. Use the Registry Editor
If you suspect that a broken registry entry associated with the dxgmms2.sys file is causing the BSOD error, then here’s what you should do:
- Press the Windows + R keys simultaneously to open the Run dialog box.
- Into the text field, enter regedit and press OK.
- Once the Registry Editor opens, go to this destination folder:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers - Right-click onto the right pane and select New. And then, click DWORD (32-bit) Value.
- Rename the new DWORD to TdrDelay.
- Double-click on this new DWORD and set its value to 10. Doing this will set the GPU’s response time to 10 seconds.
- Exit the Registry Editor.
- Reboot your computer.
