Hum in an audio system is almost always a ground issue.  The ground problem can be at any point in the signal path.  \n\nTo help locate the source of the hum you should begin unplugging audio cables beginning at the monitors and then replacing them. If you unplug a cable and the hum stops then you know that the source of the hum is caused by a device or cable somewhere before that point in the path. Keep going until you unplug a cable and the hum is still there. This will tell you which device is causing the hum.\n\nHint: If you have a mixer plugged into your monitors and the hum gets louder or softer as you adjust levels, then the hum is either in the mixer or in a device attached to the mixer.\n\nAfter you locate the source of the hum there are a few things that you can try to eliminate the hum. First try removing the device (assuming that it is not necessary for signal to get to the speakers - i.e. amp, etc) from the signal path.  If the hum is still there then it is not that device that is causing the hum.  Second you can try removing the ground (third prong) with a cheap adapter that can be purchased at most stores.  Finally you can try plugging all of your equipment into a power conditioner. However, these are expensive and a last resort solution. \n\nIf none of this helps then you should begin checking your cables to make sure they arethe right type and are not shorted.

try turning off the sound. If you continue to hear noises listen to  the computer itself. It might be a noise that is cause by the computer or monitor. Also don't hesitate to ask a mechanic or a computer fixxer it might be something wrong with it. It could be a virus. Or it might be a website.\n\nGoodLuck

Of course it goes without saying that your speakers need to be turned on.  But really, it may be something as simple as checking you connections, making sure your speakers are plugged in in the back.  They may have just shimmied loose somehow.Beyond that, perhaps checking with your local computer store.  Have a great day and take care.

set up a better ground of some sort or make sure your speakers are plugged in all the way

Are you running some media program (like WinAmp) or some sound recording program that is currently using your microphone and speakers ?\n\nIf so, you will need to stop those.

Could be because the room was full.  This is typicaly the cause, so wait a bit and try again.  There are other technical issues that could interfere, but they are less common and would require more information to diagnose.

You might be plugged into the Mike place or there might be an inline switch on the headphone set that needs adjusting.  Or they dont work.  Can you try another computer?\nE

it sounds like a broken wire.  i assume this speaker is on your computer.  in that case, if it's only one of them it could be the wiring, or the sound card output, but i'd put my money on the wire.  check that it has not been bent real hard and creased, or yanked apart just inside the speaker casing, that's typical

Try upgrading your audio card drivers. If that doesn't help, get a new sound card.

Yes, try swapping the monitors out.  The one producing the loud ringing noise makes me think that the CRT in your monitor has died.  The 50,000 volt capicator gives out and sometimes produces that noise.  It may be time to buy a new one.  But like the other fellow said, looks at the pins.  Try another monitor on your computer and see if it works--if it does not, it is your video card.

Check your sound card and video card via the device manager to make sure they isn't a problem with that.

Check your sound card software.if you are using intel motherboard then "soundmax" may be the culprit.

The monitor's high-voltage power supply is going bad.  There is nothing that you can do to stop this except replace the monitor.  Depending on the age of the teacher in the class they may not be able to hear this noise.  Your only choice is to complain to the teacher and convince them that it is making a noise.  Good luck!

try changing your refresh rate to stop that, sounds like you have the monitor plugged into a power strip so its not saving the settings
