SOURCE: dell dimension 8400 fan runs at high speed upon power on

Check if the capasitors on the motherboard are "swollen" which would mean the motheroard is KAPUT. Check if there is a modem in the PCI slots which often shorts the motherboard (when it has become faulty) ... remove the modem. Try booting again. If not succesfull make sure the POWER SUPPLY workls correctly by replacing it with another working one..... If no joy... there are still one or two other options. Let me know If you still have a problem and I will give you more options to check on

SOURCE: dell dimension 8400 fan runs at high speed upon

Your fan speeds up and slows down in response to temperature inside the computer. More so the CPU.

I would suggest getting a can of compressed air made for computers

take it outside, take of the side and blow all the gunk out of there, Really go to town around the fan (you might want to wear eye protection)
While you are in there just check that the CPU cooler itself is not loose

If it is it will have to be re-seated.

If it needs re-seating don't just take it off and put it back on as that might make things worse with your temperature problem they have to be cleaned and new thermal grease put on ($2-5)

DON'T remove the CPU just the fan/cooler assembly.

You must clean both the surfaces without scraping anything off. Use isopropynol alcohol and cotton bud sticks until both surfaces are clean, you can use your finger nail to scrape harder residue if you wish but nothing else.

DON'T pour the alcohol over the CPU

Now apply some new thermal grease (most computer shops have it)

Be careful about how much you put on

Here are
some basic instructions


Once you have re-assembled your cooler and re-connected it check everything is OK and power up the computer.

If everything went to plan you should now be back in business

SOURCE: medion desktop does not boot up, screen blank.

Had same sounding problem with a Medion PC myself. I don't know the cause exactly but the fix I have is this:
Switch off PC, switch off PSU and unplug the power cable from the PC. Then press the power button on your PC. You may see lights and fans start up for just a brief second. This is because there was still charge in the PSU's capacitors which we needed to clear out.

You can now plug the power cable back in, switch on the PSU and turn your PC on.

(I realise this is too late for the original poster's uses but others may find it useful when searching for a problem!)

SOURCE: Desktop computer fan runs constantly

Hi,

Desktop fans do run constantly, you cannot avoid this.

The reason they get loud is because there will be a build up of dust on the fan blades.

To rectify this problem turn off the computer and remove the power cord from the rear. Then you need to remove the side panel from the base unit to expose the motherboard.

You will see that inside the case it is full of dust. Look at the CPU fan (the fan on the motherboard) also take notice of any case fans too, they are at the back.

To clean the fans and the case you can use a clean dry paintbrush or compressed air.

Once the inside of the case is cleaned you will see a noticeable drop in noise.


Regards.

SOURCE: Dell optiplex GX620 loud processor fan noise

I don't think you can install 8gb of ram into that desktop. If the processor fan is too loud check it for dust or any other obstructions. If there aren't any try replacing the fan - it could be a bearing in the fan.

This is short false-alert of the time gap during start-up, and it happens on Intel based boards. Just take care of fan controls in BIOS, and try to locate missplaced fan connectors viewing the board layout. I know the lunatic who plugged a processor fan into system fan connector, and everything works fine, but monitoring is too bad, got it?

DELL 8400 MAKES A LOUD FAN NOISE AND WONT BOOT


There are 2 basic fans in Dell tower one for the power supply and the other for the Processor. If your computer is not booting then the Processor fan is most likely to be the culprit. What could be happening is that the Processor fan is no longer turning fast enough to cool the processor, so normal the processor when it over heats there is either protection to switch off the computer automatically or the computer won't boot. The best thing is to change the fan and make sure it is working properly but checking on the cables that they won't entangle on top of the fan to impede it's movement. You can easily damage your processor if the fan is not working properly.

I ve a compaq cq60-220us.. when i switch it on. it shows compaq display then it starts shouting a loud beep sound... wat do i do....... pls help...


this beep can mean anything as they are warning tones while bios checks up your system while booting. So there must be something wrong with your system hardware and in different systems different kind of beeps means different hardware problem. So 1 way is to contact lenovo customer support or take it to lenovo repair centre.
You can't do anything on your own.

Dell optiplex gx280 makes loud fan sound at startup and enters windows screen, but will not finish booting and freezes up.


You may have a problem with your power supply(the loud fan noise) and eventually it may get too hot and will cause problems like not fully booting.

Loud whirring noise when mains switched on but PC still off


Most likely worn bearings in the fans.

If that's the case, replace the fan/s.
