What is a DxDiag & how do I send one to Support?
A DxDiag is a utility designed to display the specifications of the user’s hardware, as well as to test DirectX software, including sound and video. If you are asked for this information in an email, it helps the support group relate your gaming issue to your personal computer. To create a dxdiag.txt just go to Start -> Run (or Search in Vista) and enter dxdiag and click OK. Once the program has run its course, click “Save all Information” and it will output a txt file that you can attach to your reply email.
