My Wii.... it's dying.

[DaSimkin]

My Wii seems to be dying. 

First, the cdrom has started making a lot of noise, it's pretty much as noisy as an xbox 360.... before a few days ago it was silent.

Then last night the wii wouldn't even turn on.

So has any of you had to send your wii in for repairs, get it replaced, etc?  What should I do to prepare, is there any decent way to backup everything?  Do i risk losing all my purchased/downloaded games?  How quick does nintendo repair and replace the wii?  I was planning on calling them this weekend.

Also.. is it possible it's just dusty/dirty?  Is there a way to clean it that may fix these issues?  I've had many nintendo products and never had a problem with them, so i'm a little surprised, but I have used the wii pretty much every day since launch day so i'm not very surprised.
