Buzzing and Humming

My Spider IV 15w started makeing a buzzing sound when cable is i splugged in.  When I touch the amp with my hand it seems to quiet the buzz.  In addition when I touch the ground part of the plug on the other end of the guitar cable it stops.  Does this sound like a bad cable?  I bought a monster cable thinking it was a good quality cable but not sure which is the problem.  Also, when I play for a bit it will go away.

    That sounds like a grounding problem.   The electrical circuit you have the amp plugged into may not be properly grounded - try plugging into a different outlet.

      I tried that also.  Plugged it in to several outlets and it did the same thing.  I am pretty fluent on how grounding works and all just not that much as to the internals of the amp itself.  What baffles me is eventually it fades away but really makes a loud buzzing sound at the beginning for about 5 min or so.
