computer speakers making a weird buzzing

hey yall. i recently copped my sisters old optiplex tower (p3, dell, POS) and i hooked the dayton bookshelves w/ the pyramid subwoofer up to it. it is being run through a vintage hitachi amp seen here:

problem is, the audio that comes out is kinda distorted. whenever there is like a peak in audio (loud sound like a crash) there is a buzz. i think that it is the amp since it isn't very good in the first place, but it didn't buzz THAT bad when i just ran my ipod through it. any suggestions? going high level inputs through amp > miniplug/RCA>RCAs>speaker out on computer. what should i be doin besides a new amp?

How close are the speakers to the computer?

quite close to the monitor, but a good 3 ft from the actual comp itself. u think i'm getting interference and should shield 'em?

it could be line noise, try running the speaker wire away from the power wires.
