You need to goto the HP website and look for the tech manual for the exact model number of your PC. You will need an appropriate size screw driver and make sure you remember where all the screws go! You can lay them out on paper just like you removed them. A noisy fan may just need the dust blown off with compressed air. Most new PC's have software based fan management which may auto-control the fan RPM based on what level of enery or stress the CPU is under while performing an application so the racing up and down may in fact be normal. You should investigate the fan RPM feature of your PC / OS.

My Explorer is demonstrating a high pitch noise and feels like the engine is racing with acceleration, but no check engines lights are on


I really need the year but here is what might be the cause, the engine cooling fan clutch may be defective, if it locks up you will hear a roaring noise that gets louder as the engine speed increases. Open The hood and rev up the engine does the fan make allot of noise, like an airplane propeller?

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.

Kenmore refrigerator making high pitch noise top front


could be the ice maker or the evaporator fan motor.you can try lifting the arm up on the ice maker and see if it stops,this will shut off the ice maker.also when you open the freezer door to lift the arm on the ice maker the evap fan motor should start when you open the door,you should hear it blowing around,is this the noise you hear?these are the two things i can think of that could make a noise up top,if not it could be the compressor or the condenser fan motor but these are down the bottom back of machine but still could be the problem,if the ice maker and evap fan motor both in the freezer are ok pull out the machine and remove the bottom back panel and check to see if the noise is coming from there where the condenser fan motor and compressor are,you're going to have to do some detective work to find the noise,hope this helps you out.

Samsung dlp tv HLP5663W makes loud noise


Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

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.

Hi grade laptop makes high pitched noise and the screen is blank


High pitch noise usually means the inverter board that drives the lamp behind the LCD display. If the rest of the laptop appears to work, for example, hard drive light blinking while booting, try hooking up an external monitor and hit whatever function key that switches you to the external monitor. If everything works, you may want to replace the inverter board yourself. It is not horribly hard if you are very careful. But it is not exactly a walk in the park kind of work.

If the rest of the laptop does not appear to work, the DC-DC step down power circuit is probably shot, which will also make a high pitch noise. In this case, you will have to replace the motherboard. Replacing a motherboard is a major pain in the behind. In most case, it is not worth the trouble if you have an older model.

Freezer section evaporator fan motor bearing are going out. This would be indicted by a high pitched squealing noise. Have the fan motor replaced and it should solve your problem.
