Computer making a creaking noise!

[Jeddy]

Hi guys, my pc, when powered on is making a really weird creaking noise.

I have checked all my fans to ensure cables are kept far away.

I sounds like a fan hitting a cable, but i cannot be sure.

When i turn the case on its side to investigate the sound disapears.

Sorry for my vague discription, but it is all I can think of.

Any ideas? I am planning to take a closer look when i power off the machine for the night.

Thanks jedd.

Can u get a recording dude?

I would just take the side off and make sure there is nothing that looks like a rattle suspect.

I will try and capture a recording of the sound for you jim.

I will also report that when I place the machine on carpet the sound disappears so i think it is a rattleing mounting or similar.

could be vibrations going through the case. Perhaps hard drive or fans

Take the side off and narrow it down

Could it be a cable getting into your PSU fan from inside the PSU? I sometimes have that, a fairly hard pat on the top of my PSU always solves the problem.

How loving I am towards my PSU ^^

check your fans to make sure there no unballenced by dust or that the bearings arnt going

I always do that by just keeping my finger against the center. They will stop rotating, but make sure to help them make speed again if they are not on 12V Especially with your CPU fan *whistle*

Also, have you thought about the fan on your graphics card? *does not know which card/cooler you have*

Fixed the problem, was a cheap pci slot fan i bought to provide a bit of extra cooling across my passive 8500gt. Seems the bearings were not designed to last all that long

I'll be picking up a 4870 fairly soon so its not really an issue

Hmm is the 8500 the lowest card? If so you could put a spare 80/92/120mm fan on a few pieces of packaging material at the bottom of your case blowing up. Did it with an S-flex 800rpm on my overclocked passive EAH3450 and it lowered the temps by quite a few degrees.
