How to Gather Diagnostics
Microsoft included a convenient little diagnostic utility with their multimedia technology software drivers known as DirectX. With the diagnostic utility, you can gather information about your computer hardware and even troubleshoot hardware problems. If you are having problems with some hardware in your computer or if you just want to gather more information about it, run the DirectX diagnostic utility.
