Solution 3: Repair system files

The dxgmms2.sys Blue Screen Error on Windows 10 may be related to system files. When the system files were broken or corrupted, it may cause a Blue screen issue.

There are 2 ways to solve it. Here’s how:

  • Option 1- Automatically (Recommended)
    Use a repair tool to check various areas in your computer to determine the cause of Windows common issues. It will deal with issues related to system errors, critical system files and find the right fix for you.
  • Option 2 – Manually
    System File Checker is a built-in tool to check for corrupt, damaged system files and manage to restore them if there’re any. However, this tool can only diagnose major system files, and won’t deal with damaged DLL, Windows Registry key, etc.

Option 1 – Automatically (Recommended)

  3. Fortect will scan your computer thoroughly. This may take a few minutes.
  4. Once done, you’ll see a detailed report of all the issues on your PC. To fix them automatically, click START REPAIR. This requires you to purchase the full version. But don’t worry. If Fortect doesn’t solve the issue, you can request a refund within 60 days.

Option 2 – Manually

1) On your keyboard, press the Windows logo key and the R key at the same time to invoke the Run box.

2) Type cmd and press Shift+Ctrl+Enter together on your keyboard to open Command Prompt in the administrator mode.

Note: Do NOT click OK or just press the Enter key as that won’t allow you to open Command Prompt in the administrator mode.

3) Type sfc /scannow (or copy-paste) and press Enter. Then wait for the verification is 100% complete.

4) Restart your computer to check the blue screen issue is fixed or not.

If the result indicates there are broken files but SFC can’t fix them, you can turn to Deployment Image Servicing and Management (DISM) Tool for deeper examination and repair.

Solution 4: Reset or reinstall Windows

If all else fails, you may have to reset Windows, or maybe even reinstall it together. We all know reinstalling will delete all the data on your hard drive, you have to back up all your important files before doing it.
However, with Fortect, there’s no need for lengthy back-ups, support phone calls, or risk to your personal data. It can reset Windows to the state exactly when it was just installed without affecting third-party software.

But treat these options as a last resort, because they both take quite a long time.
