Hi

as long as there is no issues with normal operations -- nothing to worry about .
That high pitched whirring sound is likely the hard disk drive ... if it's a low rpm drive (ie: 5400 RPM) it is working overtime to catch up to the demand in multitasking-- that whirring sound is actually the spindle or disk inside the hard drive spinning

HOWEVER, it appears as though (depending on the exact part # of the computer) , you have eithet 160G or 200G hard disk drive, which runs at 7200 RPM.. one or both of the models has the Seagate quiet drive .. you may have the other which is obviously not so quiet

nothing to worry about, but to prevent any issues --

make sure that your system is frequently de-dusted,, especially the power supply fan and the CPU heatsink fan. DO NOT BLOW ANY AIR into the fans without placing a small instrument to prevent the "fins" from spinning., insert something in bewteen the fins before blowing air into the fans to release all the dust.

extra cleaning measures prevents issues and extends the life of the systems peripherals.

hope this helped you !

Yes, open the side cover and determine where the noise is coming from - Harddrive, fans, DVD/CD player, etc.. If it's the harddrive, start backing up your important data asap before it goes out completely. If it's a fan, power down the computer and clean the fan. If it's t DVD/CD drive, replace the drive.

I have just replaced the carbon brushes on my Bosch classic 6 washing machine and wasn't convinced that I put one of them the right way round. The motor is now working ok but it is making a highish pitched...


I would not think putting the brush in the wrong way round would make a high pitched noise. I would look for something rubbing against the drum or check the bearings of the drum or armature of the motor.

Time to replace the pulley, you can test it by pulling off the belt and spinning the pully with your hand or some compressed air, if it makes noise then its time to replace.

Loud buzz/whirring noise, need help diag and fix


If Samsung the color wheel (part number BP96-01579A) is suspect number 1.

Wheel turns at over 8,000 rpm and commonly fails= High pitched sound or fan like sound---and when it fails (shatters) you will have a grinding sound and set should shut down.

There is an easy way to know---with owner manual remove the lamp unit (its a cartridge) and look where the lamp faces--if pieces of the wheel are missing etc the wheel is gone.

Most of the wheels are customer replaceable if you are handy. You Tube even has video instructions for most models for this repair--most sources that sell the part also provide instructions--for a first time person doing this it takes around a hour.

see attached photo of typical color wheel.

2000 Beetle Loud Whirring at start up


its your secondary air pump. it turns on in the cold morning to inject more air into your exhaust, something about emission. its normal to be high pitched. once on my car it was way loud, i looked and the hose had disconnected. either way its normal if its not super loud. but if its everyone is looking at me loud then check for loose hoses!

97 4runner making a low whirring noise/whine from engine.


Could be a possible break down of the plug wires. Seems that I remember hearing if your plug wires are breaking down inside and if its up against the motor you can hear something that sounds like interference in your radio. Just a thought, might want to check it out.

Probs with 2001 elantra h/back. Noise from r/side when driving.


Sounds like a bearing packing up. Could be a siezing alternator, which would put enough of a strain on the engine to make it cut out. Does the pitch of the noise increase with speed?
