String buzzing on electric guitar when playing unplugged?

I got this Jackson King V w/ Floyd Rose on monday 6/20/2011 and I get
this very annoying buzzing noise from the strings when I play
aggressively and unplugged. The noise occurs mainly on the last 3
strings (the thick ones) but also very slightly on the first 3. Also,
after raising the bridge to see if that solves the problem the 5th
string started making even a more annoying noise but for this one it's
coming from the bridge. the 5th is the only one with that problem.
Please help me the guitar came setup perfectly because it's a very
trust worthy website where I bought it from. Dunno what to do with it.
