I hope it is not my power supply, in a way a fan would be better, although nothing at all would be perfect
I have a filefront account and can upload the files there, if it would help someone to help me to convince this computer chappy of mine to take it in and fix it......the sound is very fine and at times quite subtle, to hear it you have to look past the motor sound of the PC.
I have named the two recordings: bearing noise and Sunday boot, the boot one has what might sound like Thunder in the background, but I think it must be the air thats being blown out the back of the case......as the Sun was out all day here
If anyone would be willing to have a listen to these two files I would appreciate it.
If anyone would'nt mind listening to them and giving me their verdict then please PM me as its probably best not to put the link here, afterall who wants to listen to someone elses Computer making weird noises
This niggle has been driving me nuts and I hear this all the time the PC is on and when the guy came he said he could hardly hear it at first and suggested it was the HD and then changed his mind and said its nothing to worry about, probably just a bearing, but its convincing my bloke to have it in and repair it because he seems reluctant to do it (he is a really nice guy though, and has helped me alot, I just don't want to rub him up the wrong way. I just can't bear to listen to this anymore.

A loose plate at the back could do it make sure all the blanking plates are tight. If you have an external microphone then putting it near each fan and see if the noise level goes up on one

It's dangerous to put your ear next to the guts of a live PC.
Having said that, I have an ancient (about 7 years old) PC that I use as a print server which sometimes sounds like a washing machine (and sometimes not).
It's possible that you have a rough bearing - or just that the mounting screws are a bit loose on a fan or hard disk and things are resonating a bit. Try tightening a few mounting screws internally, if the tubing trick doesn't work.

I tried once to connect a new HD to my PC and nearly wiped 40 gigs off it........and that was after being told what to do......so I dare not go near it again for any reason

That can be disastrous if not fixed as some things can very easily overheat and die.

Have you tried putting your ear close to the suspect fan (with the case closed)?

It seems to be a noise that when you listen from all angles it sounds like its there, if you know what I mean........noise problems are the worst for me, as most people think I am making it up, I have a tiny room I am in and so the noise is much louder than say it would be in this guys shop! I just want it fixed, otherwise I am going to get quite angry with this guy, July last year this was built and already a problem, ok so fans don't last forever, but is 9 months a fans lifespan?

Some fans have their speed controlled by software - possibly linked to temperature sensors.
So you might need to adjust speeds whilst monitoring temperatures...
It's very risky to attempt any lubrication and pausing the fan on top of the CPU is a big gamble!
Actually, large fans are probably not the primary suspects (they rotate more slowly than small fans).

I do have something called ABit Guru, but my bloke told me not to install it as for someone like me it would be of no use too.
Last time I checked that Uguru utility, it said all fans were ok, and that was with the noise, so...........?

Unless you have a super high speed/games PC I'd suggest that you try it on about 1/4 - 1/3 speed.
If you have any software that gives temperature readings I would run it, although the figures are notoriously untrustworthy.
Compare temperature readings between "just switched on" and after running an intensive CPU program (such as a CPU test program).
Absolute readings are not to be trusted - but relative ones may be.
All this may allow you to control your fan setting a little more precisely.
That Abit Guru probably gives your temperature readings + a lot more.
Read the instructions and if they are understandable (and safe) then you might decide to go ahead.

Specs:
Intel Core 2 Duo @2.40Ghz
GeForce 8800GTX 768MB
4 Gig DDR2
250 Gig Barracuda HD (XP 32-Bit)
500 Gig Barracuda HD (Vista 64-Bit)
AW9D MotherBoard Socket 775
OnBoard Sound
I have the fan while I surf down to the lowest the gadget allows, and the noise is the same, so no matter how fast they go the noise is the same

The only thing that might save my bacon is the two sound files I have, and I'll send them to him tonight if its still quiet, but I fear that he won't be able to do anything and then (I'd put all my money on it) it starts up again when I get it back.
Don't you just hate hese kinds of problems with PC's? so frustrating

Try leaving the PC off for a while and see if the problem returns.

Is it at all possible that the noise may well have stopped for good? or is it best to let him look at it regardless of the noise not being there now? is there anyway he could detect a fan being at fault without hearing it? or is that just not possible
