Your sound card could be shot. Click on Start, then go to My Computer, and RIGHT click, choose Properties. A box will appear, choose the Hardware Tab, then Device Manager. This will show all the hardware in your computer. If there is a problem with the sound card, the icon will have a exclamation point (!) in a yellow triangle. If your sound device does or doesn't right click on it, and choose Update Drivers, hopefully it will find one if it's a driver problem. Say your having no luck, download this free program called Advanced Windows Care, hopefully that will fix it if it's a software thing. Lastly unplug your speakers and plug a headset in where the speakers are to see if can hear anything, to make sure the speakers aren't toast. Best of luck

I had this same problem! It annoyed me for the longest time, but I found that it was spyware. It was also spyware that made my computer run louder and harder than normal. All you do is download a trusted adware/spyware remover, I used Microsoft BETA http://www.microsoft.com/athome/security/spyware/software/default.mspx) and its free too. Try it.

This is due to microphone feedback. Look at this article for information on how to eliminate it in Windows: http://www.findarticles.com/p/articles/mi_zdpcm/is_200108/ai_ziff10423

You probably have windows update turned on. There is a bad audio driver upgrade out there. Roll back your driver to previous, then go to manual windows update, find the update and exclude it.

No Audio Devices means you do not have a  SOUND CARD. To get any type or white noise you need SOUND CARD. If you can fit SOUND-CARD yourself then buy it from any computer shop and INSTALL it. With Sound-Card you will get DRIVERS TOO. Install that and hey bing you have sound coming out of your system. I hope this might you.

normal. but if your computer is in an encoles space on most sides, it could be overheating. just move it out into a more open area. the noise should die down a bit. but it is normal. the buzzing means that all of the grears are moving properly.

Some noises are normal and some are indicators that certain hardware like the hard drive may have a scratch on it or may be on it's way out. I would suggest backing up your data that you want to keep (Windows has a Backup Wizard found in accessories) and either wait for it to go out or have it looked at by an A+ Technician. Do not take no for an answer when you ask for an A+ Technician also ask for thier CompTia A+ Card.\nJohn\nA+ Certified Professional

Yes, it's probably broken. Try hitting your monitor & see if that helps. If you turn off your monitor & the sound stops, you'll need to get a new monitor.

Next time list the make and model of your computer and speakers, and the OS your running. With out that info all i could suggest is more sound trouble shooting:\nhttp://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=RNWK,RNWK:2005-50,RNWK:en&q=trouble+shooting+sound+issues

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