A DxDiag is a diagnostic tool used to test DirectX functionality and troubleshoot video or sound related hardware problems. DirectX Diagnostic can save text files with the scan results. Looking at this file will help you get a better idea of the PC you're using in case the issue is due to a hardware failure or incompatibility.
To create a DxDiag file simply follow these instructions:
- Launch your computer's SEARCH (this will vary depending on the version of Windows you are using).
- In the Search field type: dxdiag and hit the ENTER
- The report will begin to run (usually there is a pop up window where this happens, or a prompt where you allow it to run)
- Once the progress bar in the lower left hand corner disappears, Click SAVE ALL INFORMATION.
- In the Save As window verify the following:
A) File Name field should read "DxDiag"
B) Save as type field should read "Text File (*txt)."
C) Save in field should be "Desktop."
- Click SAVE and then EXIT.
You can review the report yourself, to see if you need to update your video card driver, correct DirectX, or see what your resolution settings are.
