If I don't fix this, what will happen? Will my computer have other problems?
If you choose not to fix this, any applications that access this file simply will stop functioning for you. Error messages of this sort are often only the first indicators that your PC's operating system is in need of some attention. Every time you install or remove an application from your computer, important files and registry entries are altered. In time, these small changes compound and Windows has difficulty making sense of the data. Unfortunately, correctly identifiying and remedying issues with a computer's operating system is a task usually far beyond the average user's skill level. If you are experiencing a “d3dx9_30.dll missing” error, we highly recommend a file scan of your computer to look for other issues that may also be contributing computer's problems and go from there. If you're experiencing issues getting certain hardware peripherals to run, you might want to take a look at Device Doctor driver updates.
