Clicking sound on my computer windows 10 volume off still hear the sound how to get rid of it?

Oh oh ... that's not a good sound.

Put your ear close to the computer case ... does it seem like the sound is coming from inside the case? If so, you'll need to act quickly.

If you're lucky, some dirt has gotten caught in one of the cooling fans. You can take care of that by opening the case and blowing out the dust and debris that has collected there, paying special attention to the fans. A can of compressed air will be helpful.

Another possible source for that clicking is the case fan (or fans.) The case fan is built into the side or the top of the case. Computer manufacturers usually put in the cheapest case fans they can find, and after several years the lubrication goes away and the fan makes a rubbing sound that may be what you are hearing. Fortunately, replacing a case fan is easy (and they're just a few bucks.) Simply unscrew the old fan and screw in the new fan. The only 'trick' is to buy a new case fan that is the same diagonal measurement - measured screw to screw - as the existing fan.

The scariest reason for a clicking sound that comes from inside the computer case comes from a hard drive. A clicking sound that comes from the hard drive means that the actuator arms are starting to fail. You'll need to replace the hard drive immediately. In the meantime, backup often!
