Whining noise from pc tower

The pc has got this annoying high pitched sound. I've checked the HDD by replacing it with another one. I've disconnected the floppy and DVD writers. The only thing I didn't check was the PSU and CPU. A pc technician advised me to remove the stickers from the fans and also the little cap and put a drop of oil on it. No result. The sound is still there. To me it sound like something on the M/B. Is it possible that a transistor on the M/B can make a high pitch sound? This M/B will be a year old in Oct.

    Thank you for your reply. I've replaced the psu, disconnected all my devices and only the motherboard was connected. The sound was still there. The cpu fan is clean from any dust as I clean my pc on a regular basis. I am a technician. This sound sounds like a capasitor or something vibrating just left from my CPU. It is not the CPU as I've disconnected it and the sound continiued. I even removed the ram one by one to no avail. The sound was still there. With only the M/B working and using 2 different psu units, it left me with the only the M/B. What really caught my attention was when I checked the bios setting and used the save and exit option, pressed enter, the sound stopped for a second. This is the only time I ever heard it stop. This sound starts very soon after start-up and the pitch stays the same allllllll the time. Sorry, I am so annoyed by this and doesn't enjoy my pc any more :-(.

    i am facing a similar problem. only difference is tht the whining/rattling noise goes away after a couple of minutes . i suspected the psu initially. but after reading ur experience i don't know where else to look. have any suggestions. the noise is a recent phenomenon. all fans are clean. noise is definately not frm them.

I found the problem about this whining high pitched sound. It came from the "onboard" speaker. Disconnected it and the noise was gone. You disconnect the thin red and black wires coming from the LED connections. Good luck!

I have an asus nct-d with two nocoma cpus and the whining noise drove me nuts.
It was the fans on the cpus. The cpus run hot and the fans gotta haul *** to keep them cool
Hence the noise.
I water cooled the system and have had no noise or any other problems since.

I hope this helps.

No transistor will make such noise... The problem is not in your M/B. The problem might be due to the fan that cools your processor. So clean dust around the fan thoroughly.

SOURCE: cpu fan noisy/chip fan fail error messages

I had tons of problems with these Asus chip fans. I asked Asus to deliver 12 replacements (as I had a lot of pcs at that time with the same problem) It worked well, but placing a tiny heatsink well glued to the chip worked well also, as long as one does not want to overclock the thing. It's true that the temp raised a bit, but it remained pretty much in the tolerance area.

Found the following paragraph on manufacturer's web site.

"The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM. "

Here's a link to Asus support site. It looks like the have a good tool for you to help troubleshoot your board.

Hope this helps and GOOD LUCK!

Loud Continious Alarm noise coming from the Piezo buzzer

You are definitely looking at a hardware problem. Your son did not cause this problem.
On the problem computer, disconnect everything but the video, power supply, memory, CPU, mouse, and keyboard.
Now try to start it up. It should start and tell you there is no boot device. If the noise continues, remove the memory and try to start it.
I'm not sure if you have an integrated video card or not, but if it's an add-on, you could try to remove that to see if you can quiet the system.
Once the system starts, plug things back in one at a time to get it working.

Having replaced my PSU, I now have a new problem. In games or scrolling in IE8, there is a loud buzzing noise coming from the CPU area. What could be done? I'm not sure if it's the CPU or the Northbridge,...

Electrostatic interference may also be the cause, for some reason, I'm not exactly sure of, there are PC's that emit this high-pitch squeal or noise when doing certain tasks on the PC, usually this can be tracked down to the sound system in the machine, but sometimes is not.

Also, some motherboards come with a safety feature that can cause the noise, it's called a voltage regulator, these can sometimes go bad, and while they may still function properly, the circuitry can emit these noises as over or under voltage is being rectified as it is passed through them. I have 3 servers here that used to do it untill i replaced the module, on a desktop motherboard, these are usually built into the motherboard circuitry and cannot be replaced.

Powers up but HDD just clicks. Tried several things...

if the hard drive clicks, there's either a serious problem with the hard drive itself, but since you already tested with a drive that is sure to work, it has to be the motherboard. the other post you read, has probably nothing to do with your own problem. try reinstalling your system board's drivers or replace the system board if unsuccessful

When I turn my computer on, all I get is a high pitched noise from the computer. It is a Cmpaq Presario SR5450F

If this is a desktop computer then chances are that one or more of the capacitors are failing. This will be high pitched sound that you can hear.

If this the case then you are looking at a new motherboard.

If you are talking about a laptop then please post back with more details.

High pitched sound from VGA

Hi there.
If this the on-board VGA that's making the sound then remove the power cord from the back of the tower, remove the side panel and inspect the motherboard for swollen and leaking capacitors, they will look something similar to this >>>>>>
If you find one or more of these capacitors you can replace them by soldering capacitors of the same voltage and ohms but usually people end up purchasing a new motherboard.

Good luck and thanks for using FixYa!!

Hard disk not dectecting

Is your Hard disk running at all ?
Can you hear some spinning noise and vibrations when it starts running?

Check the jumper settings (Master/Slave/Single).

If you have another device connected on the same cable (HDD/CD), check jumper settings on that device too.
You may first try to disconnect other device (if connected).

It is a very old PC, try replacing the data cable of your HDD, and pay attention of the correct connection of cable to the motherboard and HDD, too !
Check BIOS settings if both IDE channels are enabled.

Mother board problem

The noise must be coming from the power supply. The only thing running before you press the power on button is the PSU.
Unplug the power cord on the PSU. Check the back of the PSU for a red slide switch. Make sure it is set for 115v. Than disconnect the main power from the motherboard. Plud in the power cord, (still hear the high pitch noise?). Swap out your power supply.
