Thumbs down Our new PC really RATTLES/VIBRATES : (

Only had it since Xmas Eve but it really rattles/vibrates

Taken the lid off (or rather the "side panel" and the noise seems to be coming from the CPU area on the mobo, or it could be the fans - or even the hard drive....

... but how can we be certin please ?

It really is annoying, and we wish we could record this noise somehow to upload on here for your expert diagnosis...

could be fans, carefully stop each one in turn, just put your finger on the central boss until it stops, it should start again on its own, if not just help it

do it carefully!!!

if you stop them for a few seconds you will do no harm to the system, even the cpu one

if it is non of those, then the one in the power supply is a bit more difficult, easiest way is to put a pencil through the fan before you start the system up, that way it wil stop it turning, again no problem to stop it for a few seconds

if you suspect the hard drive, then with the power off remove the 4 pin plug from the rear of the drive and power up, the drive will not spin up so windows will not start

once you have done that, power down again and re-fit the plug to the rear of the drive,

if non of that works then ear muffs

A bamboo cane or something of a similar nature can be utilised as a "stethoscope" to pinpoint noise sources.
Don't use anything that is electrically conductive and be careful where you poke it!
As the actress said to the bishop.

Certainly serious MT. The "stethoscope" trick is used in many situations - From motor mechanics to electronic equipment.

Thanks.

Slowly stopped the main fan, noise continued.

Did same to the CPU fan, noise hasn't come back so far... touch wood.

Did get a bloody big static shock when I touched the light switch afterwards to turn the light off !!!!

If you are extremely careful, a short blast of WD40 at the middle of the fan sometimes works wonders.

This is my first post, so hello to everyone.

Another possibility is that the metal clip that holds the fan/heatsink to the CPU is loose/not seated properly and the fan/heatsink is vibrating, causing the clip to rattle.

Just go buy a new fan, you can get one for about 6 quid!

M T look at the fan closely and check that all the fins are intaked, I had a new cpu fan only 2 weeks when one of the fins(blade) broke off and made the computer vibrate and become really noise.

Could just be some of the the case parts rattling, seen that on some cases, try tightening screws that hold the drive bays or even (keep that static away) try bending bits of the case case slightly while its running, just push a few bits to see if two parts are almost touching.

I personally, like the 'bamboo' method, it may not help, but the notion is amusing. I think I will try it. The idea of checking an advanced technology with a 'primative' technique, is to irrisistable.

That said, if the suggestions made don't work, then get it checked by an accredited engineer.

Hi all. Thanks for the replies

Touch wood, but since loosening all the outer screws on the casing then re-tightening them up, things are nice and quiet - with the exception of the CPU fan but I guess I can live with that

Cheers all the same
