The red ring of death gives many customers a good amount of frustration and hardship. It's likewise given Microsoft a few problems too...to the tune of about a billion dollars or so in repairing consoles under warrantee. Now the first inquiry that needs asking is why?

What exactly are the causes for the three red lights or the ring of death? The main reason is heat. The Xbox becomes overheated when it's used continually over a period of time.

Now, why does the console overheat? There are two parts to the answer here. Firstly, the graphics chip had been designed very cheaply by Microsoft.

Instead of going to an experienced vendor for its chip design (ASIC vendor), Microsoft decided to do the graphics chip design in house, in other words, on it's own. They did this in order to save a few tens of millions of dollars in the cost of the design. We all know that to do the job right, you have to hire a professional.

It's well known that our "home made" efforts just will not work as well as work done by the pro's. Microsoft's in house job is inefficient in that it dissipates too much waste heat. The other part of the overheating problem is that the cooling system is only marginally capable of dispersing the tremendous heat put out by the home designed graphics chip.

It really doesn't take a lot to make it get too hot. Try running the unit for any length of time, particularly in a warm room with no air conditioning and it'll get too hot. The console doesn't deal well with partial blockage of its cooling vent-holes either.

For example, it is very easy to allow cables and cords to become really clumped up at the back end of the console. This by itself can induce the console to get over heated. Thinking of running it in that cluttered up recess where the midday sunlight will hit it inside that room without air conditioning?

Not a great idea in any case. Of course, you may not normally treat your "electronic toys" this way, but what I'm saying here is that a well designed product is supposed to be able to take some customer abuse and continue functioning. One question that I don't have an answer to is what happened to Microsoft's quality control process?

There must be some sort of product testing program in place to protect the customer from defective products. Maybe it was deficient in that it didn't simulate typical customer use of the Xbox. Or possibly it was ok, but management shipped it out the door anyway?

All conjectures aside, the great news is that Microsoft has already gone to a US based ASIC vendor and got the graphics chip redesigned. Maybe someday, your ordinary Xbox gamer won't know what you're speaking about when you mention: red ring of death.
