Online Support for Xbox 360 Fix?

I am a certified geek in the sense that I normally tinker on many stuff over at the Internet for many things that interest me.  I try to learn things for the sake of satisfying my curiosity.  Being a geek, it naturally follows that I am also a gamer.  I play games all the time over at the Xbox 360.  The only problem I have with that console is that it requires me to look for online support in order to find ways for Xbox 360 fix.  It is such a hassle to be able to look for ways on how to counter the failures that are inherent on Xbox 360.  I think I have to learn more about how to fix Xbox failures myself.
