Hi,
Yesterday my (1 month old) PC started making a sort of whirring resonance sound. It's not extremely loud, but fairly audible coming from the case.
The sound stops if I: open the case (it's the type the side of which can be easily opened without screws) or lift the case off the ground, or tap it gently, or gently touch a component like the graphics card. It's not consistent. The sound *can* start again with the case open. Sometimes simply moving the case door causes it to start or stop.
I don't think it's a capacitor, since if it was, I don't think moving the case door would cause it to stop (or would it).
It was difficult to diagnose, since as I said it was not consistent, and opening the case often stopped it. I did the following however:
_ Completely removed graphics card (it was my first guess since touching it often caused the sound to stop). I connected to mobo's graphics adapter. Sound still there.
_ Once I managed to get the sound on with the case open, I tried all the fans. I would quickly stop each one with a q-tip. Did that with the all the case fans and the CPU fan (I made sure CPU load was 0 and temperatures were below before doing this). Stopping those fans had no effect on the noise. I couldn't do this to the PSU fan, because that's at the bottom of the case, and as soon as I put the case sideways, the noise stopped.
_ I unplugged the PSU, did a quick look at it, but didn't notice anything out of the ordinary. Put it back. The sound was gone for a few hours, so I thought that did the trick, but it came back again this evening.
_ I did a sanity check on loose wires, etc... but there doesn't seem to be anything particularly wrong.
Any idea what could be the issue? Other than the PSU, the only thing I can think of is the HDD (I have an SSD and an HDD).
Any suggestions on how to proceed. The problem is it's difficult to diagnso because it's not consistent.
Thanks.
