HI there,

first I would vacuum the case of the computer from dust so that it gets to cool itself properly.

if that doesn't solve the problem, you possibly have too many programs open on the computer, programs can be hidden in the background and use your resources.

Might be best to have the computer restored to factory defaults.

If the problem persists there is most likely a problem with the processor heatsink, might need a little maintenance, cleaning and new thermal paste should do the trick.

but you haven't provided much information, and I have no clue how advanced or how new you are to computers.

I hope it helps.

SOURCE: Fan runs constantly

one reason that a CPU fan may be running constantly is that it may not be able to cool the cpu down. usually this could be due to dust or debri clogging the incoming or outgoing vents or even dust accumulated on the fan itself or the heatsink.

Bad Power Supply.

The blinking green light on the power supply, is a diagnostic light that indicates this.

Suggestion is to;
1) Test the Power Supply voltages
Or
2) Replace the Power Supply with a Known to be good, Compatible unit, for a test.

[Compatible:

A) It is an ATX style of power supply.
The style used by 90 percent, of personal computers out there.

Example: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4975140&CatId=106

The test Power Supply unit should be mounted in the computer, for testing.
The power cables only reach so far, plus it is safer.

B) At least a 250 to 300 Watt unit, for a test unit. More Wattage is okay.

(The power supply that comes with the Pavilion a1310n, is a 300 Watt unit.

The 250 Watt unit stated above is just for a Test.
You are testing to see if the Power Supply is the problem.

More wattage is okay as a computer only uses what it needs.
If you have a 1000 Watt power supply installed, and the computer only needs 100 Watts; the computer only uses 100 watts.

The computer Will Not burn up, by installing a power supply with more Wattage than the original)

C) Correct amount of power cables, and correct kind.

Observe the power cables from the existing power supply, that are plugged into the various hardware components in the computer, and to the motherboard.

The test unit has to have the same power cables, and the correct amount of them.

Need help identifying these power cables, reply in a Comment.

The above may sound funny. Who has a spare power supply laying around, other than someone really committed to computers?

You may find yourself, or someone you may associate with, has a computer sitting in a closet, basement, attic or garage, that has a working power supply, (And is compatible), and can be used for a test unit.

Test the Voltages.

There are three main Voltages, produced by a personal computer power supply.
(DC. Direct Current)

1) 3.3 Volts (Wires that have Orange insulation)
2) 5 Volts (Red wires)
3) 12 Volts (Yellow wires)

(Two D cell flashlight batteries are 3 Volts {DC)

ANY Black wire is a Ground wire.

Use an economical multimeter to test the Voltages, or a power supply tester.

Multimeter:
Power Supply on.
Positive probe lead (Red) connects to the power wire to be tested.
Negative probe lead (Black) touches ANY Black wire.
(Black insulated wires are Ground wires)

This is one example of a power supply tester,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

What causes Power Supply failure?

A) Inside of computer is dirty, as well as the inside of the Power Supply.

Computer unplugged from power, (Computer case open, and anti-static precautions observed), a can of compressed air for computers is used on a regular basis as needed, to help prevent this.

There are two cooling components for a SMPS.
(Switched Mode Power Supply)

1) The internal fan
2) The Heatsink's inside

http://en.wikipedia.org/wiki/Switched-mode_power_supply

A Heatsink, is an object used to draw heat from whatever hardware component, it is placed against.

A Heatsink is generally just a flat, square piece of metal, that has tall, thin fins protruding from it.

The flat metal base absorbs heat, whereby it is absorbed by the tall thin fins, and radiated away.

In the case of a Power Supply, there is an internal fan which draws air in-between the fins, helping to carry the heat away.

Once the fan blades, (Plus center hub, and surrounding cage), become coated with gunk, and the Heatsink fins become coated, the cooling capacity drops tremendously.

Heat = Wasted Energy.
The Power Supply has to produce more power, to keep up with loss of energy.
Eventually hardware components inside the Power Supply fail.

B) Cheap quality components used in the power supply. (Cheap quality power supply)

Awaiting any question you may have regarding this.
Post in a Comment.

Fan runs constantly on hp pavilion a1530n


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


First clean your computer of dust you could use a fine air blower from a compressor or a can of compressed air whatever you use make absolutely sure there is no moisture in the airlines


if the fan in your computer is constantly running to cool down the cpu and it is normal for it to increase it's speed, your fan should run quietly even it increases the rpm.


But if you hear a loud noise in the fan, i think there's something wrong with it.


I suggest for you to check the fan if it's coming in contact with anything. If the fan is visible while your computer is operating, you can observe it to know what is really happening.


I don't know what type of fan hp uses on their computers, maybe something is loose already on the fan so better check it or bring it to an hp service center.

make sure your CPU has thermal paste

your CPU might be getting hot making you computers fan to run consistently


hope this helps

Computer Freeze-HP Pavilion dv9000


I agree about the over heating. I have to take my laptop apart about once a year and clean the dust out of it. When you do this, you have to remove the fan and inspect the shroud (once I had a dust ball that had obviously been rolling around and around in the shroud. It finally got do big that it stopped the fan). Also most of these laptops have an outlet that is vented. After all, if it wasn't a kid would stick something in it or a bug would crawl in it or whatever. The last time I cleaned mine, a layer of dust had formed over this out-vent. It formed so neat and perfect that at first I didn't know what I was looking at. It looked exactly like a manufactured filter. And then it hit me - "THERE AINT NO FILTERS, ANYWHERE!" lol........ There are in-vents all around. But only one outvent. If it gets stopped up, it doesn't matter what kind of fan you have. Your computer is going to overheat.

If you find that your out-vent is not stopped up, a good experiment would be to find four things to use as spacers and open up your computer. Block the top half (keypad-screen) up and watch what it does when running open.

Another thing that just came to mind - If your computer is overheating, you should hear your fan laboring (running hard and fast) way too much. If it isn't, maybe it's the fan control circuit/program. Under normal conditions, after start-up, it should slow down and become almost inaudible.

I hope you'll let me know what you discover.

Our fan is constantly running now for the last last 3 days when our computer is on. We have the computer on all day and shut it down at night. It is louder than normal. Why is this and can it be fixed. ...


Its not a problem if you have the computer running all day long. Get an additional fan for your computer. An additional fan will reduce the noise as more fans running at low speed produce low sound that a single fan at high speeds. Make sure that the CPU is free from dust. More the DUST, higher the heat and higher the noise.

Hello, I have a problem with my widescreen. I have a laptop (HP Pavilion dv2418ca, Windows Vista, Memory 2,00 GB, Processor Intel (R) Core (TM) Duo CPU, 32-bit Operating System) and my widescreen...


It may be caused by overheating. Overheating is the main problem with HP portables. Use a fan to cool down the computer and check how long it last working. If blowing air with a fan "Appears to fix the problem" stop using the computer and get maintenance service for it. The processor area needs to be cleaned.

My cooling fan has stopped working - laptop is a hp pavilion, model tx2000


If you unplug the fan, you can test the connector to make sure the fan is bad and the problem isn't with the power getting to the fan.

You can get a new fan and heat sink assembly here (make sure the model number is the same as your computer):

http://www.sparepartswarehouse.com/HP,Pavilion,tx2000,KX531AV,Laptop,Fans.aspx

But in the meantime, you shouldn't run the computer much because it can easily overheat without the fan.

Display and Boot problem with HP Pavilion DV2125NR


It is normal for the bottom to get hot. The fan should keep it cool enough to run, but it sounds like perhaps your fan is not working very well anymore and should be replaced.

Does the computer act up at all when cool? If not, the first thing I would try is replacing the fan and examining the fan and heatsink assembly for proper installation, perhaps replace the heatsink compound with some Arctic Silver while you have it open.

Loud fan noise


hmm, it's very possible that the new fan is unable to spin fast enough to draw enough heat away fast enough. I'm guessing that this a separate video card and not the onboard video of the motherboard? and, is it the video card fan that is making all the noise?
