I know I've made one or two xbox threads lately but I'll stop after this one hopefully. I got my xbox for christmas so it's not that old. When I turn it on or start a disk up it will make a buzz noise for like, one to two seconds and then stop. It doesn't damage the disks or anything and the fan is still going. What's on-screen isn't effected either. Is this just it starting up and nothing to be worried about? (I hope.)
EDIT: It's now doing it in the middle of a game for much longer. I need advice/help. :c
Thanks,
Ok, final, final questions.
This is where and how my xbox is placed.

It's a cold room with a bit of dust. (It's an old house.) This will change by Feb 16th when I get my new room. By then it will be on a nice cold desk in the open air along with my wii. But for now, does this look ok?
