Loud buzzing noise

Buzzing is a cue that the transformer windings are loose. Time to replace it if you want silence.

This is do to an electrical component on the Power Supply board oscillating. This is not an issue, only an annoyance. You can send it in to get it fixed, but it is not a hazard.

try downloading the game from disc to harddrive and playing from the harddrive

Seems like the fan should be cleaned. If it is making a loud buzzing noise it usually means the fan is working extra hard. Hope I helped.

i had this problem too. if you bought the xbox 360 when it first came out the power box is the first version of the 360 and it will be loud if it isnt hurting your games this isnt a problem i can understand it is annoying though. the reason it does this is that the 360 is computer software so it will be loud like a computer but they made improvements in them if you buy a new power box it will decrease sound greatly i have done this with my own xbox. i hope this helps

Mine is loud also when playing games. When playing DVD's it is not. I think it is a factory defect on some of the systems. I would not attempt to pull apart the DVD drive and try and fix it. It is working and on an XBOX 360 you should feel lucky that it is.

the loud buzzing noise isnt the xbox its the powerbox the one tht you plug the power cord into b4 u plug it into the back of the xbox when the buzzing happened to me i just shook it and it went away

From what i understand, the dvd drive can spin wonky allowing the disks to foul and cause large scratches
