Sorry for poor english I hope you understand what I mention below: Here it comes:
There is a continous high pitched noise coming from my own-built desktop PC. The noise starts just after 5 seconds when the computer posts and it never stops. The noise is independent from any action... it is always there if I play games, use windows or when it is idle... it is always there. The noise is not in extreme but it is still disturbing and I worry that it damages my ears because it leaves clanging in my ears after using computer. When I sit in front of the computer for a long time I forget about the noise especially if I use headphones. But I know it is there and it is giving my ears some pain.
Please help me identify which component is causing this high pitched noise
These are the components and how old they are:
MOBO: GA-965P-DQ6 http://www.gigabyte.com/products/product-page.aspx?pid=2453#sp (4-5 years old)
CPU: Core Duo E6600 (4-5 years old)
Rams: Corsair 2x1 GB (4-5 years old)
GPU: HD 5770 (2 years old)
PSU: 460 W Feel Hurricane http://img.cimri.com/pictures/wm/300x300/573/573586_300-300.jpg (PSU is eldest, 6 years old)
In order to find out from which component the noise is coming I disabled or removed some parts... I shut down all case fans... I removed GPU... Disconnected power and sata cable of HDD... I even disconnected CPU fan power... And just motherboard and PSU stayed active... The noise was still there...
So I guess it left me only 2 components to suspect... Motherboard and PSU... cleaned both parts from their dusts a day ago and nothing changed... I opened PSU case and checked inside to see if anything was wrong but I don't understand well from it... it only seemed to me that the two huge capacitors in it had a little bit bulge on their tops... But maybe they are normally so because their tops were plastic. PSU seems to have low quality....And it is really 6 years old... But computer seems to be running fine with it... and like I said I disconnected almost all parts and only CPU was running on MOBO and noise was still there.. and this cpu is only 65 W component which draws just couple of Watts in idle mode.
I suspect more from the motherboard somehow. I get my ears close to it in order to identify the exact source of the noise but I can't.. it is like as if coming from everywhere from this huge motherboard not from a certain point...
I connected 3 systems to this same PSU just some days ago.. One system was its original.. A p4 system.. There was no such noise in this pentium 4 system.. Then I connected AM3 socket ati with x3 455 athlon triple core there was no noise again.. and before this one I connected a 1155 socket with sandy bridge pentium g620 and there was a similar noise but less than this one....
Is it the motherboard or PSU ? What do you think ? given these facts...
The computer seems to work fine once it launches. Only somehow yesterday it did not post and restarted itself. I powercycled couple of times and it started to run again. During this ordeal GPU was disconnected which actually draws lots of power...
Today full system is working but with that high pitched noise... but it is killing my ears seriously....
I have a tight budget... I plan on changing the PSU first because I am happy with the system itself. I can play every game with max details in 1680x1050... But if it is the motherboard well I ll replace it too...
