You do NOT need to run the Recovery. I don't know why people immediately go to that rather than attempting to fix the problem? It would help to have more details about your system & exactly what your son did.
Computer Makes High Pitched Noise When Turned On Tv
Were any plugs removed from the PC to connect the DS or was it just connected to an unused USB port? Did he just yank the plug out without using the 'Safely Remove Hardware' option? Did you check to make sure no other cables were disturbed? Are there any error messages on the screen or just the continuous tone? I assume the tone coming from within the computer case rather than thru the external speakers? More than likely what you're hearing is a BIOS Beep Code although it may be something simple like a stuck key on the keyboard. The BIOS beeps are unique to the BIOS used by the motherboard, so we would need to know the make/model of your system to be able to look up the code. Here's the list for Compaq, but there are other codes listed in the right side column:

Under normal use, motherboards should be silent: the only noises a motherboard should make are optional boot message beeps and ambient noise from any fans attached to devices that connect to the motherboard. High-pitched noises coming from a computer motherboard can indicate a failing component. Very high-pitched noises that are higher than what a person could emulate with their voice indicate hardware problems. It can be difficult to be sure the motherboard is making the sound because other parts like the power supply unit make similar noises when failing.
Motherboard Code Beeps![]()
A single, split-second high-pitched beep is normal for some motherboard models: the sound indicates that the system is ready to boot. Other motherboard beeps, which vary in pitch within the human singing voice range, are used to identify hardware problems with the device. If the motherboard won't turn on correctly, there's no way to view the error code on the screen, so the beep sound functions to tell someone trying to fix the computer what the problem is. Motherboard beeps are clearly audible and frequently use syncopated pulsing patterns. The beeps will stop if the computer is able to load the operating system.
Loose Inductor![]()
A loose inductor can create a very high-pitched noise that's difficult for many people to even hear. Indicators are usually anchored on the motherboard and create micro-vibrations as a part of their normal use. However, if the inductor comes loose from the motherboard it may start vibrating ever so slightly -- but incredibly quickly -- such that it produces a high-pitched noised similar to the ringing someone hears in their ears following a very loud noise. Inductors are used on the motherboard to prevent irregularities in the electrical current from damaging other hardware components. A loose capacitor won't damage the system, but people who can hear it might find it annoying.
Failing Capacitor
Failing capacitors make an indistinguishably similar noise to loose inductors: an extremely high-pitched ringing noise. Unlike loose inductors, failing capacitors are a serious problem for motherboards: if they go, the motherboard will have a difficult, if not impossible, time operating. If you open the computer and look at the motherboard, failing capacitors may appear to be bulging out of place. The motherboard will need to be repaired or replaced if a capacitor fails; it's usually a wash with the price because of the cost of labor to repair the device.
Fan Failure![]()
When a fan starts to fail, it makes a high-pitched squealing noise. Some motherboards with built-in graphics cards and high-end northbridge chips come with installed fans. However, the majority of the fans in the computer are not connected to the motherboard and are more likely to be the cause of the high-pitched noise: many are so close to the motherboard it may be difficult to pin down the exact source of the noise. If a motherboard fan is failing, it should be replaced as soon as possible to prevent the part it cools from overheating and breaking.

I noticed a high pitched noise in my daughter's room a few nights ago and thought it was coming from an R/C Transmitter.
Last night I noticed it again when the transmitter was clearly off. So I investigated and noticed that her computer (which was shut down, but the PSU was still active) was the cause of the noise. I flipped the pwr switch on the back of the PSU (Antec SL400) and the noise slowly attenuated away. When I flipped the switch back on, I didn't hear the noise again. My first guess is that something is up with the PSU..but also thought that it could be something on the motherboard (Asus A7N8X). I haven't used her machine much of late, nor I have I heard any issues from my daughter about the machine actually being unstable. Anyone have any idea what could be causing this high pitched tone?

Sounds play an important role in troubleshooting a computer. Computers have pre-programmed beeps and sounds that notify you of clear hardware issues. Then there are the subtler sounds: a high-pitched whine or squeal that starts one day is a sign that something isn’t working exactly correctly. If you’re willing to take one of the computers in your office apart, you can identify the source of the sound precisely.
About Working Inside a Computer
Computers are full of moving parts and electrical pulses, so working inside of a computer is a delicate process. There aren’t any exposed electrical currents, so you needn’t worry about the risk of shocking yourself, though you may have to worry about the risk of shocking your computer with static electricity. But if all you want to do is identify the exactly cause of the noise, taking the case off of your desktop PC isn’t going to cause any problems. You can't do this on a laptop, however. A laptop's construction and layout, with the connectors between the power button on the outside and the motherboard on the inside, means you can’t work inside a laptop while it's on. There's no way to have the laptop taken apart and to turn it on at the same time.
Finding the Noise
With the case off of the PC, disconnect all the peripherals -- printer, mouse, keyboard, monitor and any USB devices you have connected to your computer and turn the computer on. Wait for the high-pitched sound to begin and then listen carefully, moving your ear around near (but not touching) the motherboard to find the source. It’s more likely that the noise will be coming from the fan or the hard drive than any of the electrical components, but it’s best to identify it with the case off before continuing troubleshooting.
Motherboard or Not?
If you’ve taken the computer apart and still can’t identify the source of the sound as something directly on the motherboard, try temporarily disconnecting the CPU fan and the hard drive to eliminate those as the source of the sound. Turn the computer off and then unplug the red, black, white and yellow cord from the back of the hard drive. Turn the computer on and see if the sound has stopped. If not, turn it back off, reconnect the hard drive, and remove the red, black, white and yellow cord from beside the fan over your CPU. Turn the computer on again and see if the noise has stopped. Both of these devices can produce high-pitched whirring sounds when they begin to malfunction, though the sound isn’t a harbinger of compete device failure.
Electrical Sounds
Occasionally, high-pitched sounds coming from the motherboard are from electrical components in the system experiencing a strong charge or malfunctioning. The power supply can emit a high-pitched sound if it experiences a surge. “Squeals,” according to Tecca’s Matt Jessell, can be ominous signs, indicating the chips and capacitors on the motherboard are failing. When you start to hear a high-pitched sound that you can’t identify, consider replacing the computer in your office.

A friend just gave me an old E-Machine T1842 that he had had laying around for quite a while (maybe a year since it had been used). He said that it was working the last time he tried it, but when I went to turn it on for the first time, it didn't power up. It didn't do anything, except it does make a high pitched buzzing sound as soon as I plug in the power cable.I'm really a novice when it comes to diagnosing computer problems, so any suggestions as to where to start would be appreciated. Thanks for your time. Comments are closed.
