its called ground loop... very common with computers
To get rid of it, try connecting the powercord to a powersupply without ground
Or get a ground loop eliminator from your local radio store

if your power cord looks like 3 circles in a triangle (the part that plugs into notebooks powersupply)
you can use 2circle (wire) whitch is normally used for radio or shaving-machines
you just have to cut it with the knife in the middle in order to enable it to stretch a little and fit
into the bottom 2 holes in your power supply. This solved my ground loop problems
your new power cord should look like this

the side which you plug into wall is probably different than show on the pictures ..

Ground loop eliminators are cheap. $15 here in the U.S. You could probably get a 3 prong ->2prong adapter for $2.
I'd recommend either of those solutions over performing surgery on your power cord.
Here is a ground loop isolator $16.99: http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=270-054 This exact unit solved my groundloop noise problems.
And here is a 3 prong ->2prong adapter for the power cord that might do the trick, too. $2.99 for two. This might not fit your particular style of plug, but should give you and idea of what to look for as well as a clue to the price. http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=61-2720

or you could just get a power extention cable, that does NOT have ground, and connect pc to that...

Get a 2 prong adapter witch converts a 3 prong to a 2 prong. It will ground it for you. they cost about 3 or for dollars
