Well to tell you the truth about HPs and their makers, they use junk parts to save money to help rip off those who don't know any better.
I have owned and have had many given to me to fix, and let me tell you, they are the most problematic computers I have ever worked on in my life. I hope you'll reconsider about getting another HP and maybe go with a DELL or a Sony if you want a pre-built computer from a corporation. But to be seriously honest with you, if you learn how to build them, you'll save about $500. In my life time alone dealing with HPs, I've went through a good 15 of them in 8 years. And I still have my old IBM from 1992! and it still works! :D If this one dies on ya, buddy, my suggestion to you is to quit buying them... I did.
