First of all - hi, guys. This is my first post, I have browsed the forum a while to see other users' experiences, but decided to ask a question in here, I hope you can help. I have carefuly read Tomcat's rules and I hope I am doing everything right.
The board is a Gigabyte GA-8IPE1000-G, rev.4.0). OK, I know this board is quite old for these modern day PCs, but I use this PC for everyday use, not much for gaming, some work, and all I need for it is to work fine and reliably.
OK, here is the potential problem.
A few weeks ago, I have noticed a strange "whine-like" noise coming from the PC housing. These are the conditions when it happens:
1) When PC is turned ON, everything is fine, BIOS POSTs normally, Windows starts to load, and just when the screen with Windows loading logo is to disappear and a blue Welcome screen to appear - then the niose starts. It last maybe half a second, but is a highly pitched one and it can be heard very clearly. It happens everytime at the point right before a Welcome screen is to be displayed. The PC loads after that normally most of the time (though it happened several times it simply shut the monitor off saying "No signal" and I could clearly hear that Windows continued to load - I can hear the login sound and all the HD activity), but the screen remains blank. Sometimes it simply restarts on its own.
2) If the computer has started normally and did not freeze or halt, then there is a new possibility for that same noise to be heard; when HD is doing some certain task (I do not know what they are, could be a self-defragmenting thing or Windows doing something). Anyway, when that "state" is achieved the noise is heard and it follows the blinking ot the HD Activity LED (when the LED is ON and HD is doing somethin, the sqeeling noise is heard).
So, I opened the case to inspect what is going on in there. A few days ago, I bought a new PSU and it is a SeaSonic SS-660KM. I thought that the noise was triggerd by a faulty or a failing PSU (the previous PSU was really old and not that much of a quality), but the noise is still present. I have also tried two different graphic cards and the noise is still there. I was thinking the noise might be coming from the GPU because it regulary happend when Windows was loading, switching from DOS's (Windows loading screen)resolution to the Desktop one (Welcome screen), but clearly it is not that.
By listening carefuly every time the PC booted up, I narrowed the area down around the CPU socket as a source of the noise. My GA-8IPE1000-G board has two Nichicon 6.3v 1500uF (HM)M caps sorrounding two very small caps in between them, which are yellow and so small I can't read the data on them. Anyway, neither cap looks deformed nor bulged. The board is exactly like the one on the posted image.
PC is clean and very well taken care of. There are no dirt or dust deposits, that is regulary being cleaned off. I relly have no idea what else could it be, but the board serve(d/s) me well and now I feel like it is a time bomb, waiting for something to blow.
Could the failing cap be the source of this noise which apparently is a bad thing because PC doesn't boot normally from time to time?
Thanks in advance for any reply, guys. I hope I (we) will get to the bottom of this "mistery".
