Do you have anything attached to the "door"?

ih8bills · #17 11-22-2007

Could be a heat-build up -- when the side panel or door is on the case the internal temp rises just enough to cause the failing part to become noisier.
A failing bearing in a fan-motor or harddrive could be this sensitive to temp-fluxes.
I would suggest you download HD tune:
HD Tune
it will confirm or eliminate the drive issue-- if it eliminates it-- great-- if not-- you'll want to backup files right away.

Thanks, the hard drive is ok and healthy, what do you think is the problem?

ih8bills · #19 11-25-2007

Did you run the error-checker tool in HD-tune ? Run the normal version-- it takes a while-- but it's more thorough
Or are you just going by the normal temp-display ?

Cooling fan-- could be case fan/CPU fan/ Video card fan/ Power supply fan--

I ran the error checker

what temperature is the harddrive running at? and what are the results of the test?

OK good that pretty much eliminates the drives- It will probably take some detective work to find which fan it is

Speedfan--http://www.almico.com/sfdownload.php

is a good little free temp monitor-- however -- it is not perfect-- nor are the sensors they build into motherboards-- if you see some really ludicrous temps-- the sensor is bad -or incompatible with speedfan.

if you go into your BIOS-- there maybe a "hardware monitor" tool ... you could check your CPU temp and be pretty sure it's accurate

One odd thing I would suggest is to find a stethoscope-- that way you could try to figure out where it's coming from--- some auto mechanics use them to pinpoint/diagnose burnt bearings.bad pushrods etc. Those have a solid metal rod where the doctors chilly pad would be

thanks for your replies, i have used speedfan before and have found that the nvidia control panel i got with my gpu is better for analysing temps, the noise is not present at this time but when it starts i shall get the temp monitor on the go and shall report back

Derekjerry · #24 12-29-2007

Hey, at this present time, the noise is audible, cpu is 27 degrees, system 33 and gpu 54, all relatively cool temps, cpu fan is low rpm- around 1600. i really think its the Power supply, when the pc is off (but not when the power supply is off) it makes a buzzing noise, i would appreciate further input to my problem, thanks

If you think it's the Power Supply Unit-- at this point I'd tend to agree... especially if it makes noise when the system's powered down.
Fortunately decent Power Supply Unit's can be bought fairly cheaply.
Newgg now offers a free Power Supply Unit calculator...but they don't ship to UK

Newegg - Power Supply Calculator

or there is Extreme's...
eXtreme Power Supply Calculator v2.5

I generally add at least 100 watts for a safe margin.
Be sure to add in all your hardware-- including peripherals (USB draws some power)

Please do yourself a favor-- buy a good-quality brand-name...there's a lot of junk out there

well i thaught that antec were good, i dont know if this is linked but the last couple of days the pc has been turning on, while i was in bed, it turns on without me pressing the power button, so i have to turn off the Power Supply Unit power button so it wont start up.

Geekgirl · #27 12-29-2007

I would say the Power Supply Unit also, when you disconnect the power cord to the back of the PSU that noise should go away. I have seen this before and it is the PSU that is at fault.

I use Antec Power Supply Unit also, never had any issues with them. I also use this little ATX which has great reviews.
