Remember to back up your important files before making major changes, just to be on the safe side. Let's get to the good stuff – the fixes!

Troubleshooting Steps: Fixing dxgmms1.sys Blue Screen

Now, let's get down to the business of actually fixing the dxgmms1.sys BSOD. We'll start with the simplest solutions and work our way up to more advanced techniques. Follow these steps carefully, and you should be able to get your system stable again. Let's start with the basics.

Step 1: Update Your Graphics Drivers

This is usually the first place to start. Outdated drivers are the most common cause of the dxgmms1.sys error. Here's how to update them:

1. Open Device Manager: You can find this by searching for it in the Windows search bar or by right-clicking on the Start button and selecting "Device Manager."
2. Expand Display Adapters: In Device Manager, click on "Display Adapters" to see your graphics card(s).
3. Update Driver: Right-click on your graphics card (e.g., NVIDIA GeForce RTX 3080) and select "Update driver." Choose "Search automatically for drivers." Windows will search for and install the latest drivers if available.
4. Alternatively, Download Directly: If Windows can't find the latest drivers, go to the website of your graphics card manufacturer (NVIDIA, AMD, or Intel) and download the drivers directly. Install them after downloading.
5. Restart Your PC: After the driver update, restart your computer to apply the changes.

If updating drivers doesn't work, don't worry. We've got more tricks up our sleeves. Moving on!

Step 2: Roll Back Graphics Drivers

Sometimes, the newest drivers aren't the best. If you recently updated your drivers and started experiencing the BSOD, it's possible that the new drivers are causing the problem. Here's how to roll back to a previous version:

1. Open Device Manager: Just like before, find and open Device Manager.
2. Expand Display Adapters: Locate your graphics card under "Display Adapters."
3. Roll Back Driver: Right-click on your graphics card and select "Properties." Go to the "Driver" tab and look for the "Roll Back Driver" button. If the button is available, click it and follow the prompts.
4. Restart Your PC: Restart your computer to apply the changes. If the BSOD is gone, you've found your culprit!

If rolling back the driver isn't an option or doesn't resolve the issue, let's try some other solutions.

Step 3: Check for Hardware Issues

Sometimes the problem isn't the software, but the hardware itself. Here's how to check for hardware issues:

1. Run a Memory Diagnostic: Faulty RAM can cause all sorts of problems, including BSODs.
   • Type "Windows Memory Diagnostic" in the search bar and run the tool.
   • Choose to restart your computer and run the tool. It will check your RAM for errors.
2. Check Your Graphics Card: If you have another graphics card, try swapping them. If the BSOD disappears, your original card might be the problem. If you don't have an extra card, take it to a repair shop for testing.
3. Monitor Temperatures: Overheating can cause system instability. Use monitoring software (like MSI Afterburner or HWMonitor) to check your CPU and GPU temperatures. If they are too high (over 80°C or 176°F), you might need to clean your PC's fans or improve cooling.
4. Inspect Connections: Make sure all the cables inside your PC are properly connected, especially the ones related to your graphics card and power supply.

If you find a hardware problem, you may need to replace the faulty component or get professional help.

Step 4: Run System File Checker (SFC) and DISM

Corrupted system files can also cause the dxgmms1.sys error. The System File Checker (SFC) tool can scan for and repair corrupted system files. The Deployment Image Servicing and Management (DISM) tool can help too. Here's how:

1. Open Command Prompt as Administrator: Search for "cmd" in the search bar, right-click on "Command Prompt," and select "Run as administrator."
2. Run SFC Scan: Type sfc /scannow and press Enter. This will scan your system files and attempt to repair any issues.
3. Run DISM Commands: After the SFC scan is complete (and even if it didn't find any issues), run these DISM commands one by one:
   • DISM /Online /Cleanup-Image /CheckHealth
   • DISM /Online /Cleanup-Image /ScanHealth
   • DISM /Online /Cleanup-Image /RestoreHealth
   • These commands will scan and repair your Windows image.
4. Restart Your PC: After running these commands, restart your computer.

These scans can sometimes fix underlying issues that are causing the BSOD.

Step 5: Check for Software Conflicts

Sometimes, other software or applications can cause conflicts with your graphics drivers or DirectX. Here’s how to check for software conflicts:

1. Clean Boot: Perform a clean boot to start Windows with a minimal set of drivers and startup programs. This helps identify if any third-party software is causing the issue.
   • Type "msconfig" in the search bar and open "System Configuration."
   • Go to the "Services" tab and check "Hide all Microsoft services." Then, click "Disable all."
   • Go to the "Startup" tab and click "Open Task Manager."
   • Disable all startup items.
   • Close Task Manager and click "OK" in the System Configuration window.
   • Restart your computer.
2. Test for Conflicts: After the clean boot, test your system to see if the BSOD still occurs. If it doesn't, start enabling services and startup items one by one (restarting after each one) to identify the problematic software.

This step can be time-consuming, but it can help you pinpoint the conflicting program.

Step 6: Update DirectX

Since dxgmms1.sys is part of DirectX, ensuring you have the latest version is a good idea. However, Windows 10 and 11 usually update DirectX automatically. You can try reinstalling DirectX, but it's not always necessary. Here's how:

1. Download the DirectX End-User Runtime Web Installer: Search for this installer online and download it from a trusted source (like Microsoft's website).
2. Run the Installer: Run the installer and follow the on-screen instructions to reinstall DirectX.
3. Restart Your PC: After the installation, restart your computer.

While this might not always fix the BSOD, it's a good troubleshooting step.

Step 7: Reinstall Windows 11

If all else fails, the problem might be a deeper issue with your Windows installation. Reinstalling Windows is the most drastic solution, but it can often resolve persistent problems. Before you do this, make sure you have backed up all of your important files.

1. Create a Windows 11 Installation Media: You can download the Media Creation Tool from Microsoft's website to create a bootable USB drive or a DVD with the Windows 11 installation files.
2. Boot from the Installation Media: Restart your computer and boot from the USB drive or DVD. You might need to change the boot order in your BIOS settings.
3. Follow the Installation Instructions: Follow the on-screen instructions to reinstall Windows 11. You can choose to keep your files (a clean install) or erase everything (a full clean install). I recommend a full clean install in this situation.
4. Reinstall Drivers: After installing Windows, make sure to reinstall your graphics drivers and other necessary drivers.

This will give you a fresh start, eliminating any software-related conflicts or corruption that may have been causing the dxgmms1.sys BSOD.
