Why dose my computer make a noise?

Question

It sounds like a fan working but is so loud. My computer is only 18 months old

Answer 1

You may have dust and dirt build up on the fan(s) inside your computer. With the computer unplugged, open the case and take a can of compressed air (about $2 at Walmart) and blow out an dust on the fan(s), openings, and through the rest of the computer.

That should not only reduce the noise, but keep the air flowing better so that the computer does not overheat and die. Most computers need to be cleaned about every six months.

If the noise continues after that, then the fan has gone bad and you will need to get it replaced.

Answer 2

There are a few reasons why a system would make a loud noise. Only one of those reasons is the fan. A fast spinning hard drive sounds almost the same. Since it is less than 2 years old, it is probably still under warranty. You might want to dig out the paperwork from your purchase and find out where you can bring it for service. Unless you can find a psychic tech on here ... (oooh! That gives me an idea! ), with long distance hearing abilities, you probably won't get a decent diagnosis.

I Do suggest you check the CD drive for a disk! I've seen that happen before.....

Have a great day! :)

Answer 3

It may be that you have dust in the fan, or that a cable inside your computer has moved and is touching the fan.

If it is a laptop computer, try blowing very hard into the fan holes in the case. Close your eyes or you will get dust in them!

If it's a desktop computer, you can try the same. Also if you can, open the case very carefully (switch it off, but don't unplug it) and blow onto the cpu to clear the dust. Check to see if a cable is touching the big fan inside. Also, with the case off you might be able to get a better idea of where the sound is coming from.

Answer 4

There are only few moving parts in your computer that may make noise if becomes faulty.

As you said fans (on Power Units, Processor), Hard disk which have rotating disks are main things from where noise can occur.

If your hard disk is getting wornout (mostly after years of usage) it makes scratching noise. If any of the cables touch the fans - you hear noise.

Answer 5

There could be something wrong with the RAM stick in your computer. I had the same problem. I thought the computer was going to explode at one stage!

Because the RAM isn't working properly the computer is having to work harder to compensate, hence the noise.

Answer 6

i think the fan first. low-priced to change, 20 money or so. different than that, there is not any longer many shifting areas in a gadget to make that noise. that's a threat the tensepersistent is going undesirable, yet commonly isn't a growling sound.

Answer 7

if its under warranty, contact the computer manufacturer, they should replace it for you .. if its not, you might have to get a new power supply for this computer

Answer 8

broken fan. have to be changed as soon as possible (can damage your PC if it stops running)
