To avoid going in great length, for this is very benign matter.

General rule is always to isolate the problem source, you obviously know yours.

Unless you made to general description and failed to mention there is (always is) also prior power on on your machine as well?

Machine alone if in overloaded socket might create such anomaly.

PC is really office machine, not purist, dedicated audio machine.

Isolate power socket where you have your computer hardware and remove all audio on different ones, if you can dedicate single dedicated sockets specially for audio even better.

Or simply, take one long cable with enough sockets from different room that is not already compromised with load from PC.

Or you could simply purchase better audio power conditioner like one of these :

This is just example you can go much cheaper or for High-End much higher.

But power conditioner is something to be inside any responsible (if quality of signal is important) studio or home setup.

You also said nothing about size or model of your screen?

There could be in cheaper models poor isolation and too close near (I doubt) speakers, still capable of creating such delicate but still enough to be heard higher frequency noise.
 
Try moving the monitor away from the speakers, and see if that helps. My 19" CRT-monitor doesn't affect my speakers, but my 15' Flat Screen makes a noticeable hum in my speakers. Be sure to seperate and isolate all power, audio, and PC cables, to reduce interference (Obviously if wires need to come near each other they should cross at 90 degrees). Also be sure that none of the wires are coiled up. Keep them as straight as possible, coiled wires act like an antenna. And definately consider buying a power conditioner for your most sensitive equipment (Mixer, Preamps, Speakers, Computer, etc.).
 
One more point,

Many * Tour De Force* landmark products such as SSL,Euphonix,Neve…use regulated almost hospital grade power supplies that are designed with power conditioners by deafult.

This be all to maintain absolute zero compromise in signal domain and to guarantee that condition from every I/O.

So, I cannot stress enough how important is Power conditioner for any decent setup.

There is also very cheap trick, (I admit in contradiction to sense presented here) you could also synchronize common ground of both LCD and Amp that loads your 8’s.

No, forget about that, go healthy way :)
 
thank you so much everyone who replied, my set up is in transit right now(on sight stuff)...however i will definately try this...thanks again
