Question about Dell Dimension 1100 PC Desktop

Power supply fan is loud!

I would like to know what type of power supply I need for a Dell 1100 desktop. I called Dell and they told me the part # was H2678 and that it was a 250 watt power supply. I see plenty of power supplies available at many different locations, but I really don't know which ones are compatible.

I think that with a system as old as that is you should find one that has a 20 pin and the form factor should be ATX. I found one that should work here it isn't bad for the price.

It looks like you need an ATX power supply. You could go higher than 250 watts, but don't go lower. 300 to 400 watts should be a sufficient replacement. Any bigger would be overkill.

The PSU will fit an ATX case. Therefore you will look for yet another PSU that will fit an ATX case. However, make sure the motherboard connector pins are 20 or 20+4. Since this PSU only has a 20 pin connector for the motherboard you will need one that matches, otherwise your computer won't be turning on. ;-)

You can find some great PSUs online here. Simply go to Computer Hardware>Power Supplies. Then on the left select: Power Supplies.

Have fun, let us know what you find so we can ensure it will work.

Essentially any Standard ATX power supply with a rating of 250 Watts or higher will work

Fan makes noise on my Dell Inspiron One 19


Usually there is a fan on the CPU heatsink and a fan in the power supply.
Open the case and turn on the computer and use a small timber stick and poke it into the CPU fan to stop it spinning and if the noise stops then this fan needs replacing.
If it is OK the the fan in the power supply is faulty. I recommend you replace the power supply because there are dangerous voltages inside this power supply.

Dell 370 fan runs loud and won't start


If the fan is failing the most times the computer will not start because it will overheat. There are two fans inside the system, one inside the Power Supply and one that sits on the motherboard.

Remove the Power Cord, Open the case, Remove the cover and with a can of compressed air blow out the dust inside the computer. Clean the dust away from the Fans, Vents, CPU and Heat Sink are that sits under the Fan on the motherboard.

Dell XPS 410 power supply fan loud and computer is running slow


Hi,

This issue happens when your computer is using or requiring a large amount of power source or the power supply is simply dying out already. You may want to update the BIOS. If the problem perists, replace power supply.

I hope this works for you. Good Luck!

Thought it was the western digital harddrive,bought a new harddrive and the problem is the same. The computer when running gets very loud. Now I am wondering if the problem is actually the power supply....


Your P.C. may need cleaning inside, Dust may of gathered in Fans, HeatSink, etc. When you connect things to your P.C. normally extra power is needed from help run the process. Hence why your P.C. gets more noisier and things get hotter needing the fans to cool them. Or your Power Supply Unit (PSU) replacing for more Watts.

My computer fan speeds up whenever I'm on the


Nothing ... probably ... your fan speeds up when the processor temp goes up ... the more you are doing, the more cooling you need. The processor is calling for more cooling so the fan runs faster.

If this is a concern for you, you may wish to consider adding another fan to your case. In any event, make sure your power supply fan is clean. Use a vacuum or canned air to clean.

The fan of dell gx280 producing a loud sound, how I fix it ?


Sometimes something is stuck in the grill and the blades keep touching it, other times the bearings have worn down and the fan or entire power supply needs replacing.  I used to hit my PCs noisy fan with the palm of my hand and the loud noise stopped!

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 Dell desktop


Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine.
If you have any other questions let me know.

XPS 600 serious Boot up Problems!


sounds to me like the fan is on the way out ,and if the cpu gets too hot the pc will shut down.
check that the fan is not obstructed,clean it if it is full of dust, replace it if it is not working as it should.

also listen to the power supply fan, is it working ok,this could cause the same type of problem but for different reasons.

good luck

can you be more specific when describing the computer 'struggling to restart'? Does it beep? Does it take several attempts to restart?
