You need to get it checked out ASAP.  If you have multiple fans, do they all seem to work ok ?  Is the power supply fans working ?  I have seen/smelled computers in the past where you can smell burning plaster/rubber smell if the power supply is not getting enough ventilation from the fan.... usually this is caused by a bad fan or fan that just doesn't work anymore.  But that smell is a pretty good indicator that (usually) something is overheating.\n\nYou should at least check for hotspots in your case, and verify that airflow is adequate for all areas within your case (i.e. fans still blowing air). Any electronic components that are exposed to overheating for any length of time will likely fail.\n\nAnd yes, it could be potentially dangerous for your PC components to keep your computer running with that smell permeating.

Your cpu fan may not be working. You need to replace it before you computer overheats.\n\nThe CPU fans are not expensive, and easy to install. If your computer is a name brand computer, you can usually search the company's website for instruction on how to replace it.\n\nGood luck

Might be overheating. Do you head a fan running inside? Also make sure that all vents are clear and clean. You may want to carefully take it apart and clean all fans and cooling fins inside.

Check the Processor Fan first.. this is the main thing that creates problem.. If its not working or covered with dust, the processor is getting heated and is not responding.. Clean ur cabinet removing all the parts.. check the cabinet or SMPS(power supply) fans.. if these doesnt work, try reinstalling the operating system, backup all the data into a partition and format the partition having Operating System.. Data wont get lost.. and also restore default settings in BIOS if nothing goes right.. before restoring, write down all the settings..

First: open the box and clean the inside, focusing on the fans.  Use a vacuum cleaner and don't forget the fan that's in the power supply.  DON'T open the power supply (that's dangerous, even if you've disconnected the power cord which you should do before opening your computer), just move the vacuum cleaner over the fan blades.  While you're at it, clean out the rest of your computer as well; be gentle as not to break anything.\n\nThen put the power cord back into the power supply, do NOT close the computer, and switch it on.  Is it more quiet now?  Congratulations!  Shut down your computer, remove the power cord again, close the computer, and plug the power cord back in.  You're done.\n\nIt's NOT quiet [enough] yet?  Listen closely to what is causing the noise.  Replace the culprit, or have it replaced by someone who knows about computers.  Fans aren't terribly expensive, and neither are power supplies.  (If it's a fan, and not the one in the power supply, you could try to put a VERY little bit of WD40 on the axis of that fan.  The axis is usually covered with a tiny sticker, which you'll need to remove.  The fresh oil usually makes it hard to put the sticker back on, and when you don't succeed it usually doesn't take long before the oil dries up.  You'll be back at square one again.  So replacing the fan is probably a better solution.)\n\nGood luck!

In my experience, this usually indicates the CPU fan is not working properly and with Dell machines the issue isn't the fan itself but rather the system board to which the fan is attached to.  you'll have the replace the system board the resolve the issue

Check your Cmos setup, if there is no setting for the fan, then i would not worry about it, it better to be cool than hot....It must be a Dell, just joking.....they have the most complaints....

check if the cooling fans are working properly.\n\nthing is, you might have to get a better cooling fan for your processor, or move your PC to a cooler place.

Did you check the fan? It may be getting overheated for some reason.

If your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

The cooling fan cycles on and off, and can be quite noisy when it is running.  If the noise is on sometimes and off sometimes, that's probably it.

i used to get buzzing noises... they were either from my old 256MB graphics card (2 years old)...or it was my CPU fan... I used to lubricate the fans to shut it up...had to do that every month...

Sounds like your processor is overheating and the laptop is shutting down to save it.  Make sure that the way you sit with your laptop does not block its fans.  If you're not blocking the fans and your laptop is still under warranty, then take it in and ask them to do some stress tests on it.  Tell them there might be a cooling issue on your processor.

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.

Sounds like your processor is over heating...that will definitely shut down your computer.

Possibly your power supply fan.  Check to see if it has a lot of dust in it (at the back of your tower).  If it does, then you need to get some anti-static air spray and blow it out.  My Dell used to do that, but I always believed it was because something may have just been loose, and it was the case--all I had to do was tighten it up.  So, if you're computer savvy you could check out the innards to see if the IDE/SATAs are pluged in properly and if your processor fan is getting dusty--do the same to it, if it dusty.\n\nNow if it is more like a 'beep', then that means your computer has encountered an error.\n\nGood luck.
