| 862675 | 2010-03-01 06:39:00 | Hi I recently built a computer for a mate and he's told me that every so often it would make this high pitched squealing noise for a few minutes then stop. Just needing to know what this noise could be? Any Ideas??? Thanks |

You can (carefully) try to stop the fan spinning with the use of a pencil and see if the noise immediately stops. | Jen (38) | ||

| 862679 | 2010-03-01 07:40:00 | It's not the video card fan as this stopped working and replaced it. Video card has no extra PCI-E power connector. I just googled it and found this : if its not mechanical, it could be a capacitor or inductor squealing, this can happen as they overload or heat. and could be anything from psu, mb or vga. I'm so hoping it's not the Mobo. |

| 862681 | 2010-03-01 07:44:00 | Is it under any particular conditions that it does it? I know when i stress test my graphics it sorta whistles, could be under load when it does it? | hueybot3000 (3646) | ||
| 862682 | 2010-03-01 09:03:00 | most likly power supply. they typically squeal a high pitch when going out of spec (ie starting to go faulty). | tweak'e (69) | ||
| 862683 | 2010-03-01 09:08:00 | Is the sound coming from the monitor or the system case? I've had old CRT monitors make a very high pitched squealing sound at times. Most annoying too! :) | Rod J (451) | ||
| 862684 | 2010-03-01 09:15:00 | if its not mechanical, it could be a capacitor [or inductor] squealing, this can happen as they overload or heat . Don't know where they got that from . :confused: Inductors/transformers are a common noise source through magneto-restrictive effect, which makes them whistle, squeal or sing . They often do this even in the absence of any fault, especially if the winding is not secure or the core is cracked . However, capacitors do not squeal . In well over 40 years in electronics I've heard capacitors sizzle, and I've heard them hiss, and those sound effects are usually followed by a loud pop or bang, but I've never heard one squeal . Once a cap starts making noises it usually dies within a few minutes . Cheers Billy 8-{) |
