It sounds like it has died and blown up (last time that happened to me it smelled bad too.)

    When I read this post again I have noticed you said "I have a high pitch noise coming from speakers" this is most likely the BIOS. Record the beeps and BIOS version and type (eg. Phoenix) then look it up online.

High pitch screeching on my pc cannot fix thru speakers check ok


Unusual noises coming from your computer can mean anything from serious trouble to no problems at all. The uncertainty, together with the expense of computer hardware components -- not to mention the risk of losing data and being without your computer -- make it important for you to investigate any unusual sounds as soon as they come to your attention.

Normal Sounds
Not every high-pitched sound coming from your computer suggests a problem. Computers also generate a variety of sounds as part of their normal operation. In particular, anything that spins can easily make noise. This includes cooling fans and the hard drive. In the case of fans, their sound sometimes grows louder when the computer works harder because it needs to run the fans at a faster speed in order to dissipate the extra heat from the higher level of operation. You probably don't need to concern yourself with an unknown high-pitched sound unless you have used the computer for a while and the sound is new. b> Capacitors Capacitors sometimes make a high-pitched buzzing sound, either when under a high load or when defective. In the latter case, faulty construction can cause gas to build up inside the capacitor, which then vents under pressure and sometimes creates an audible noise. Defective capacitors can damage or destroy other hardware. f you suspect a bad capacitor, or don't know what else it might be, give your computer an inspection. b> Capacitors Inspection b> Your computer has capacitors all over it, including on the motherboard and on nearly everything that plugs into the motherboard, so tracking down a bad capacitor can take some time -- especially if you don't know whether a capacitor is actually causing the problem. Many capacitors look like tiny little soda cans and smaller ones look like squat cylinders. Failed capacitors usually bulge out at the top or have crusty residue around them. Be sure to check not just the motherboard but also any other hardware components with visible capacitors on them. If you find a bad capacitor, keep looking in case you find more. Afterward, don't use your computer again until you repair or replace the faulty hardware. Fans b> The bearings and motors on fans sometimes go bad. If this happens then the fan may begin to whine, whether or not it stops working. If feasible, open the side panel of your computer tower with the system running and try to pinpoint the exact source of the sound. If you can determine that the noise is coming from a fan, power down the computer and replace that fan. b> Power Supply Unit b> Power supply units sometimes make a high-pitched whining or droning sound; it can happen continuously, when you perform certain tasks on the computer or when you take the power load high enough. This can happen either because of cheap construction or because the unit is too close to maximum capacity. As you would do to check the fans, open the side panel while the computer is running and put your ear up to the PSU. If this is where the noise is coming from, replace the unit with a high-quality model and upgrade to a higher power output if you need to do so. Hope this helps.

My Acer Aspire 5100 laptop makes a loud high pitched consistent noise when I try to turn it on. then the noise stops, then a black screen comes up with writing, but when i hit resume, the computer restarts...


The problem might be the power supply charger that plugs into the laptop, unplug the charger and run the laptop on battery power, is the high pitch sound there when you power up? if this solves the problem, it is the power supply charger that is the cause.

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


Hi,
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.


Regards.

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.

I have an Intel PC that has suddenly picked up lots of static


Forget the magnet. Noises like the ones you describe are usually because of a few things: 1) the hard drive is going bad, 2) a fan going bad, or 3) the CD drive is making noise. I'd like to know what the error message reads. And yes, you are correct that restarting the computer with the power button will sooner or later harm your computer.

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.

High Pitched Sound


I am to believe that your static sensor on the playing head is touching the the head and it sould not. just bend it up "slightly" and the noise should disappear
