Well Tzu I have actually had this happen to me it lead to the death of my Xbox its starts with only having to eject and what not a couple times and the game would work but as time progressed it only got worse to the point where it would take me like 15 minutes of ejecting and closing before the game would work then I would play for five minutes and the game would red ring also I did try everything I got the second external fans to try and keep the xbox cool I use 2 cans of air to try and clean the lesn as well as a Cd lens cleaner to no avail I hope you have better suggestions then what I have said tho cause for me it means your xbox is fried
