What are d3dx9_31.dll Error Messages?


Dynamic Link Library d3dx9_31.dll Errors

d3dx9_31.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like d3dx9_31.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 3DMark.exe - to follow. These files were created so that multiple programs (eg. 3DMark Basic Edition) could share the same d3dx9_31.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when d3dx9_31.dll is attempted to be loaded either when 3DMark Basic Edition is starting up, or in some cases already running. Some of the most common d3dx9_31.dll errors include:

Your d3dx9_31.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with 3DMark Basic Edition), or deleted by a malware infection. Furthermore, d3dx9_31.dll file corruption could be caused from a power outage when loading 3DMark Basic Edition, system crash while loading d3dx9_31.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix d3dx9_31.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your d3dx9_31.dll issue. These troubleshooting steps are listed in the recommended order of execution.

  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the d3dx9_31.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If you are not currently backing up your data, you need to do so immediately.

CAUTION : We strongly advise against downloading and copying d3dx9_31.dll to your appropriate Windows system directory. Futuremark Corporation typically does not release 3DMark Basic Edition DLL files for download because they are bundled together inside of a software installer.
