Problem with my computer

This passed few days, my computer just shot down itself and I don´t have any idea why. I get irritated because I never experience this kind of problem for almost two (2) years, just this passed few days. Perhaps our computer need to be clean up that´s why I am searching the net about registry cleaners reviews so that I will learn why computer need to be clean up. And I was not disappointed because I found what I was looking for. And hopefully, after registry cleaner, my computer will works like it used to be.
