My new xbox of less than 2 weeks old makes a buzzing noise on some games I play.

I noticed it on Madden 2004 and Brute Force. It hasnt stopped the games from working nor have I ever had and errors with reading the discs but it does sound like its the cd drive. It must be this because when you invoke it to spin differently the buzzing stops ie) when you change option screens or it loads a different part of a level etc. I was wondering because ive read about something someone else put about a buzzing sound of death, relating to the early xbox machines going faulty shortly after purchase. My manufacture date it 10-04-2003 so surly these dont have the same prob? My machine is UK.

Anyone know if the xbox buzzes sometimes and if its `normal` for it to do so?

I dont mind the normal cd drive type hum of spinning up or down, this sound i have is definatly a buzzing sound, and sometimes its annoying if it goes on a long time.....

Thanks
