Noise coming from CPU

qitian92
My cpu makes this constant clicking noise sort of like the sound made when you click a pen repeatedly. The noise starts when i turn it on and only stops when i turn it off.

Aside from it being very irritating, my cpu is functioning perfectly fine.

Whats happening?

    If that is the case look at the Keyboard as you have a sticking key.

    If it is coming from inside the case either a fan is hitting something like a loose cable or there is a build up of dust and other crud on the Heatsink and the fan is hitting that.

    If it's the keyboard you might be able to fix it by raising it 4"-6" from a flat surface, turning it over so that the Keys are facing down and letting it go. If that does'nt work replace it.

    If it is a cable inside the PC that is hitting a Fan, shut the PC down and turn off the Power at the oulet and remove the Power cable. Remove the cover from the Case and remembering to ground yourself by placing the back of your hand on the Power Supply Unit and not moving your feet. By not taking this precaution it is possible that you could inadvertantly cause damage to the PC from an electrostatic discharge.

    Do a physical check of Cables around the Fans to make sure that they are not touching. If they are they can be held out of the way by using plastic Cable Ties. <b>Do not use Glue, BlueTac, Paper Clips, Paper covered Wire strips or Elasic bands.</b>

    While you are there I would give the inside of the case a blowout with compressed air and use a small soft bristled paint brush for the stubborn stuff. When blowing air through the fans make sure that you physically stop them from spinning, as they may generate power and **** something up.

    When you are using the compressed air for cleaning out all the dust and crud, be careful to keep the CAN of compressed air UPRIGHT, unless you have bought a can that states on the label that it can be tilted or inverted.

    The reason for this word of caution is that when the can tilts beyond the upright, the propellant can suddenly squirt out of the nozzle / plastic straw, in liquid form.

    As with all computer components - liquid, particularly under extreme pressure, is not a good idea.

    Because your computer would shutdown before this. The noise is coming from somewhere else, so open up your case and find out, it will usually be the heatsink fan bearings going that will be clicking, replace your fan on top of your heatsink.

    Please post back if you have any more problems or questions.

    The sound is distinctively coming from the cpu and not the speakers and the cpu is about a few weeks old so i dont think there would be any dust build up.

    I checked the cables and they are not in the way of the fan. Could it be the hard disk that is making this clicking sound? If it is, what should i do?

    If that clicking sound is coming from the Hard Drive it could fail at any time. Return it to the Supplier under your Warranty Agreement and they will give you a replacement. Unfortunately you will be without a PC until the problem is fixed.

    Let us know how you get on.

    Well i wont be without a pc as the hard disk i was referring to is from an old computer that i added on top of the new one and another old one. So i think the warranty would have expired by now.

    Do you have any advice on how i can try to fix it myself? Another problem with this hard disk is that my pc cant seem to detect it. It can detect the other additional one just fine. We'll i lose all my data from the old hard disk?

    all that you can do is recheck your Cables and Jumpers. If its still not detected it has gone to Silicone Heaven. If it is detected try this.
