[quote name="Mark420" post="86021" timestamp="1156753117"] I get an anooying rattle every now and again from my big tower its normally dust and cat hair built up on the fans.. One thing I do to stop a build up of dust is too get my vacuum cleaner tuen the PC off!!! take out the power cord..start the pc so it drains any power left in the capacitors in the PSU. I literally hoover the PSU out-make the fans spin round and use a brush for cleaning the floor to dislodge the dust a bit..Also I hoover my CPU and graphics card fans out and make sure that theres no loose dust and fluff lying around the case. This normally solves the problem for a few months. Good Luck!![/quote] [quote name="Mark420" post="86021" timestamp="1156753117"] I get an anooying rattle every now and again from my big tower its normally dust and cat hair built up on the fans..

hey my computer make that whir rr r r r r r .. Sound when I start my computer. When I kick or shake the CPU it stop and start again in aonther 30seconds ,I hav clean all the hardware but it only work for a day and goes back to that normal sound

The fan makes a grinding noise if the barrings are dirty or if the fan itself is shot.

My computer's power supply fan long ago was making that sound whir rr r r r r r ..

It did that for a while then one day the noise was gone...

I thought oh cool it resolved itself..

Umm no...What did happen..

I was using the computer and poof it turned itself off like someone pulled out the plug out..

I booted it back up and it kept turning off all by itself..

itTurns up the power supply cooling fan had died.. The computer has aFinal fail safe system that shuts the computer off if the computerOverheats due to a blocked or dead cooling fan.. (hey!! good info toKnow you all think?? and that info should be in BIG LETTERS in allComputer instruction books because how the heck are we suppose to knowThat other wise???? it took me 3 months to find out what was wrong withMy computer.. Its no fun to be in the middle of something say like whatWe are doing here and suddenly the computer just shuts off!) IReplaced the fan and everything returned to normal.. No more noise.. NoMore shutting off

replace YOUR fan!

problem will be solved... Period... They don't cost much and are very easy to replace. Radio shack should have them..

Fan noisePc Making A Strange Noise

My PC made a grinding noise too. Turns out it was the little fan on the graphics card. I never thought to clean it, I just moved it back and forth until the noise stopped. The card ended up dying because of overheating, the new card I got has the same problem, but just lightly touching the fan fixes it, I think I'm gonna clean it out sometime.

If it is not a hard drive going bad, your fans might need to be replaced. It could be your dustys lint filled fans. Fan's typically have a long life. But there are times when too much fine dust, dirty, smoke, or other airborne contaminents can affect the noise output by fans.

Also on a side note if you pc is full of lint and dust, it may tend to run hotter because of less clean surface area to expel the heat. This will lead to the cpu, chassis, and other system fans to run faster and therefore louder than normal. They might run from a 50% speed to as much as 110% the fan's maximum rated speed.

Overclocking also has this negative effect.

Last time my computer made a grinding sound my hard drive died x_x

I faced this "grinding" problem till a few days ago - and then I opened up everything and cleaned them out. For the first few days everything was alright. Then the noise returned, although muffled a bit - so I opened everything again and was surprised to see dust again - I guess proper air circulation is necessary to stop the dust and that is something I didn't have earlier. Anyway I'm glad I'm not the only one who faces these grinding noises - everyone who used to hear them said "Your PC is one of a kind!"

I'm guessing that you are using to much energy.

My PC is noisier than standard computers since I use a rack system to hold the hard disk in the computer (i.e. the rack system allows me to change hard disks easily so I can use multiple sets of hard disks on the same computer). The rack system annoyingly includes integrated fans which makes very loud noise even though there isn't much dust in the fan.

@HellFire121,
Have you checked out the power supply fan? On my old computer, there was a small design fault in the power supply that caused it to produce strange grinding noises from within the computer. It would usually get worse in cold weather and make much louder grinding noises.

You should try opening up your computer case while it is running and try to identify the source of the noise, although you will need to be careful not to touch any moving parts e.g. fans.

Ive cleaned out my pc the fans and everything a few times am it was fine for a day but got even louder so I looked in my case to see anything wrong but nothing seems wrong I cant see any thing but dust so I clean the whole thing out and nothing it still makes louder noisesUnless I hit the side of my tower really hard then it gets quieter but I cam still hear hummingThanks :)

whoa thanks for the replies, anyway it definatly wasn't the hard drive (which is at the front, the noise was comming from the far back).
so the next time i hear this noise i'll just get all the dust out with a compressed air can.

thanks
