Having computer performance problems and especially a "failed to start because d3dx9_36.dll was not found" error can happen to anyone. It always appears when you never expect it, just as you are about to shut down your pc, and by now you probably find yourself trying to figure out how to get rid of it. Read my review and i'll show you a quick way how you can easily fix it.
First of all, there is no need to be worried - with windows systems with today's technology it is much easier to identify and repair various system malfunctions. First you need to know what dll files are. Dll (dynamic-link library) files are part of any program; they include data which is critical for your installed programs to be able to run. Errors caused by these files usually happen after installing a new version of software over an 'older' version, and also after uninstalling programs. When an improper installation/un-install process takes place, then this is most probably the reason why you start having these concerning red popup messages.
Surprisingly or not, the majority of these errors can be easily fixed even if you know nothing about fixing computers - you can easily repair a "failed to start because d3dx9_36.dll was not found" error by installing a recommended Windows registry fixing application. These tools focus on examining your Windows and repairing dozens of windows errors including 'broken' DLLs. The quickest way to try and eliminate these errors can be done by installing one of these utilities and letting it scan your pc - you'll quickly find out that most of them offer free pc scans.
A little tip before you start spending hours on web searches, or paying hundreds for a technician to remove this "failed to start because d3dx9_36.dll was not found" error, I would advise you to simply download one of these registry repairing applications and let it quickly scan all your dlls, identify and eliminate the problem(s) that you've encountered (keep in mind that there are hundreds and even thousands of these files on your pc). Don't miss this opportunity - a wide range of of these applications not only offer free pc scan, but free of charge fixes (limited in most cases), so you might be able to fix this problem in just two minutes from now.
