Ive gone through 4 xboxes.
it could be alot of problems.
ive encountered 2 of them and fixed them both.
if your xbox is making noise it could be your dvd drive.
and it can be easily fixed. theres how-to vids on youtube.
its a magnet that comes loose on units that have a hitachi dvd drive.
another could be some components could not be fully wired to the motherboard. if you want you can go inside your xbox(voiding the warranty of course) shut off the fan, run your xbox and let the solder heat up, let it cool and the components wil be connected again.
this could fry your motherboard so only let your xbox run without the fan on for around 10mins. ive done this twice. once it worked for only a couple months after and the second time its lasted 5 months and still going.
your best bet is going to the xbox website and look for instructions for exchanging yours.
i heard its lengthy process(a couple months.)
ive never done it rather i just go on kijiji or craigslist and buy cheap used ones.
