What does it mean and how do I get rid of it?

What kind of noise does it make? My moniter makes siren like noises sometimes, I always thought it was because of overheating.

Monitor's model and technical specifications?

window xp, the moniter sounds like a heater..making those sounds

I think there's been a misunderstanding. I was asking for the brand and model of monitor you are using, as well as its settings; if anything to make sure it is running according to its technical specs.

lol heaters make lots of different noises.
