Now I can say that xbox 360 halo edition is most worst xbox or game console that I have ever used. From starting days it is giving me hard time. From last week I am feeling that DVD player is noisy at all times and producing lot of vibration, fans are also a bit loud. I had done all thing that I can do like I had open the cabinet and clear all the dust from inside I had also changed the fan before. SO now I want to ask from you guys what now I have to do for fixing the problem? Why my xbox 360 halo edition is producing such type of noise and vibration?
