The Microsoft XBox 360 was released in 2005 and it was almost immediately apparent that all was not well in the the gaming world.   Although the Xbox 360 was one of the best gaming consoles ever released, few owners escaped without having some kind of technical problem, ranging from extremely minor to fatal.  This led to a rash of information appearing on the Internet but unfortunately not all this information was reliable or correct, so if you had a problem and didn't have warranty you were in for a lot of time on the net attempting to validate any and all the information you could get or the loss of your system for 4 to 6 weeks and a large repair bill at the end of it all.

The most common cause of xbox problems is overheating often exacerbated by today's modern gamers frequently having  sessions lasting well over an hour.  Without a sound knowledge of how to troubleshoot your console you will be sure an expensive repair is on the horizon unless the console is still in warranty, and even then you know it's going to be away for at least a few weeks.

So, knowledge is required, but where to get from, we have already established that trolling through the internet could be a minefield of conflicting information.  There are several repair guides out there but not many offer a full refund for failure, full online support, instant delivery, and simple instructions with step by step videos.
