How long have you had it?
Where'd you buy it from?
I'd take it back to the shop if it does die, rather than send it to MS.
Take to shop = nice new replacement*.
Send to MS = get given a refurb.
Have a read of this, regarding your statutory rights as a consumer under the Sale of Goods Act 1979 (as amended)

* Unless the shop is arsey / staffed by idiots & they refuse to abide by consumer law etc. In which case, you contact Trading Standards & Consumer Direct, get advice from them, then contact the shop's head office, mention all the advice, plus the *law*, & threaten them with action via the County Court (Small Claims Track).
