because it has fans inside it to keep it cool

First, do you mean that it's beeping over and over or is it giving you a constant tone?  If it's a constant tone, see the last response about the power supply.  If it's beeping over and over, read on.\n\nIs this beep happening during POST or after the OS has loaded (or both).  If it's happening while BIOS is loading, it is most likely not related to your OS.  Replacing your CMOS battery may resolve the problem, but will be most effective if you unplug your system and then change the battery, as this will reset CMOS.  After doing this, you may need to change some BIOS settings.\n\nHow old is your system?  If it is fairly new, and from a known manufacture (HP, Dell...), there may be a FlashBIOS update for your system.  \n\nAre you getting any warning messages during POST?  The beeps are often due to simple keyboard or mouse errors.  You could try switching out your input devices, to see if your BIOS does not like them.  You might edit BIOS to disable the quick POST.  This will allow you to see exactly what is happening during your boot, and may show you some error. \n\nYou say the sound continues after you remove the speaker?  From where is the sound coming after the speaker is removed?  Perhaps your system requires exorcism.

is the fan on the power supply working? The ticking noise could be the hard drive...it may be failing.

Two most likely culprits:\n\nPower & Heat. \n\nFirst clean out your computer. Get rid of the dust, clean off the fans. \n\nIf that doesn't work buy additional system fans.\n\nIf that doesn't work replace your power supply with a larger wattage one.

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.

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

The armature  of your hard drive might not be working properly and this generally leads to this clicking noise. \n\nSuggestion.\nPlease backup your data as your hard drive will stop working as soon as S.M.A.R.T monitoring in bios reports Failed and thisgenerally happens witing 3 to 4 weeks after the noise starts coming from the HDD(It actually depends the way and time for hich you use your computer).\nIf your had drive is in warrenty then give  it to you hardware vendor .. it will be replaced.

Is the noise still there you may have something running in the back ground. Shut down and reboot. If noise is still there call tech support.

This happens to me. It is a radio frequency issue. Ususally if you have some kind of wireless device near your computer, the radio frequency interferes. For me, it is my cell phone near my speakers. I always know when my cell phone is going to ring, because my computer speakers make that same strange buzzing noise before hand. I think this problem is primarily systematic with cheap $20 COMPUSA speakers.

If your processor is making loud noises, you would need to open the case and air blow the dust that's cluttered in your processor.  Dust gets collected in there, and it's good to dust it out often.

Its prob the power supply. Does  the fan turn on ???\nYou might want to replace it ( $ 60 ) . Also make sure that the power button is on . On the back of your computer theres a little button . \n\nAlso check out my free computer articals at http://www.cityredding.com/computerhelp

If you have a motherboard with onboard sound that could be the culprit.

in case of heating up you should hear the fan spinning much faster, long before the laptop is shutting down - do you? it's pretty noisy. If you don't hear that, you should check the fan. Maybe you have a hardware test program delivered with your PC (e.g. Dell laptops have such a test program).\n\nFurther on, check the airflow channel from intake to exhaust in the laptop and remove all the dust in it, this will improve the cooling behaviour remarkable.

Buy a WATER COOLING SYSTEM. it is silent and will fix your problem... or go the cheap route and buy new fans.

It all depends on what is actually making the noise.  See if you can figure it out where it is coming from.\n\nIf it is something like a CPU fan, or the PSU fan, then it could just be that they have some dirt in them and it's wearing down the bearings.  IF it's the HD, then start worrying, coz that could mean that it's on its way out.

If a hard drive is making a lot of clicking noises, it's about to crash!
