The computer in my sig. is emmiting a high pitched hum. It starts when the computer is on put sometimes studders or starts and stops frequently. I have listened to it and it seems to becomming from the I/O port/processor area, not the HDD. Does any one know what this is or what could cause this type of thing? Should I be worried about this? Thank you.

Thats what I thought/hoped it would be, but I stopped each fan one at a time and the noise was still going on.
:confused:
 
You don't say what type of motherboard you have.

I'll tell you this: I've experienced this on Asus motherboards primarily. The motherboard (CPU area especially) will emit a high pitched electrical sound, which can be heard when scrolling up and down web pages, or when the CPU is under load. It almost sounds like it's coming from the capacitors.

I'd also like to know if this is a problem. I've heard it was due to having a low quality PSU, but I've heard it even on systems that have high grade PSUs.
 
It could be the PSU. Did you eliminate that possibility? Just throwing that into the mix.

Yes, I do have a Asus mobo, a OEM Asus A8M2N-LA. (AM2) So has the Asus mobos yuo have had experiencing this sound have any related problems. Thanks

Also, the smartpower psu seems to not be the cause, but I am aware of the problems that Antec has had with them.
 
Have you done something to verify that the smartpower is not the problem? Just last week as a matter of fact, my computer started to make a high pitched whine; I switch ed the smartpower II-500 in it out for a TruePower 350 and voila, no whine.
 
If the sound is coming from the MOBO, chances are it is the voltage regulator inductors close to the CPU. If you have a hot melt glue stick gun, applying hot melt glue to the inductors usually solves the problem.
 
Thanks for the replies, I will switch the PSU,s and report back, but I am pretty sure the sound is coming from the motherboard.

Frank4d,
Once I get my usb ports working I will post a pic of my board and could you circle which inductors or all of them I should hotglue. Thanks
 
Maybe check the capacitors, see if any of them are bulging or otherwise looking like they're going bad?
 
I know this seems obvious, but my asus mobo has the worst chipset cooler imaginable. Make sure you check your chipset fan, if your chipset has active cooling.
