Question about HP PC Desktops

1 Answer

Very loud buzzing noise from laptop, underneath - most likely fan but am no expert so could be the drive? Noise starts about 2 minutes after powering it up from having been off all night. Guarantee ran out one month ago (!) I live in Buckinghamshire, I believe it is a hardware problem, the laptop was my daughter's 18th Birthday present last June, she is at college, so I would like an address of a competent HP technician who can provide spare bits.

Hi,

If the notebook is working fine otherthan the noise comming from the notebook, then you can try to download ans install the latest BIOS update for your notebook.

If you contact HP support with your notebook serial and product numbers, they can provide the BIOS update download link.

If the notebook is not working at all, I mean if there is no display on the notebook, then you have to try power drain.

Here are the steps to do power drain:

Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

If there is no display at all even after power drain then you can try remove and reseat the memory module (RAM)of your notebook. You can get manual on how to reseat the manula from HP.

As I said before, if the notebook is working fine otherthan the noise you have to get the BIOS update from HP.

There is free chat support from HP to get the BIOS update.

If you want to check if the sound the comming from the harddrive, then you can check the Harddrive from BIOS.

In BIOS you can find this option. If you want to know how to open the BIOS, then get back to me with the exact model number of your notebook, so that I can help you.

If you want to contact HP authorised service center then,

Please follow the steps listed below for assistance in locating a local HP Authorized Support Provider.

1. Go to the following Web site:
http://hp.infonow.net/bin/findNow?CLIENT_ID=HP_LOC_USA_SRV

This will take you to the find a US local HP authorized service
provider page.
2. In the category menu select the appropriate HP product.
3. After selecting the appropriate category you will get a list of HP products in the Family box. Select the family in which your
product is located.
4. After Selecting the family of the product you will get a list of
products under the product list.
5. Select your product from the list under the product section and click Next.
6. Follow the instructions on the service options page.
If no stores are located, repeat the search using another zip code within your local area.

I tried to provide complete infromation on this.

Dell Dimension E520 Hard drive constantly buzzing


This could be a sign of a failing hard drive - I would backup all of your important documents immediately to an external drive to prevent you from losing any important data.

As you have already cleaned out the dust , there is a chance that one of the system fans (or the CPU fan) may be faulty or some wires inside your system case might be catching on the fan while it is spinning.

Disconnect all the system fans , so just the CPU fan is left plugged in and then switch on the system and see if the noise has stopped. Then plug each fan back in one at a time to identify if any of them are causing the noise.

Katherine,

Many times when a desktop is making a strange buzzing noise - it is due to a fan malfunction of some sort. Other reasons include a power supply that is faulty or possibly a bad internal speaker.

I would first check the fan(s) for the computer. Start by turning the computer off all of the way. Next, unplug the cords from the unit. You'll need to isolate just the computer tower itself. Next, you'll want to get some compressed air or a vaccuum and gently clean out the areas where the system case fan vents are. If you know how to open the case for your desktop, it wouldn't be a bad idea to make a quick visual check inside of the case for things that may be caught in the fans. Some desktops open via screws on the back plane, and some open with a pull tab/lever.

If cleaning out the dust doesn't resolve the buzzing noise - then you'll need to make sure that the noise is not part of the electronics. If you are hearing an actual electrical buzz and not a speaker or fan noise, then there is likely a larger problem with the computer. In that case - I would take the computer to a certified professional for diagnosis.

Another culprit of buzzing noise may be a CD/DVD drive with a disk stuck in it. Make sure that you have ejected the drive to ensure no disk is stuck in the drive.

I hope this information helps!

After im on it for about five minutes it makes a loud roaring noise and freezes. The noise doesnt stop until i turn it off.


Sounds like a bad hard drive or a bad CPU Fan. Try a different hard drive in the machine, and see if the machine boots up without making that sound and locking up. If it does then that means the original hard drive is bad.

If its not the hard drive then, replace the CPU fan and see if the sound goes away, if it does then you know the CPU Fan is bad.

Hello I have a Dell Dimension 3100 desktop. After


Bad Fan... either the CPU Fan or the Power Supply Fan or the Case Fan. If the PC is older than 4 years it is probably the Power Supply.

Acer aspire4920 makes loud noise at start up


This could be caused by the harddrive. There might be a bad bearing or something. Please backup all your data. You will probably have to replace the hard drive sooner or later.

Computer noise


More likely one of the fans, but could be the hard drive. Open the case and listen. Fan on power supply, fan on processor, or hard drive are the most likely sources of the noise. Processor fans and power supplies are both cheap and easy to replace. Hard drive is a bit more expensive and you must back it up (which you already regularly do, right?) if you want to keep your data.

My computer makes a loud noise in the fan


The drive door issue may indicate a virus infection. As to the fan, you would have it replaced. If not under warranty open the case and track which fan the noise is coming from

The only sure way to quiet it down is to replace the hard drives with newer ones, that you have selected based on their noise rating, AND to replace all the fans in the machine with fans that you have selected based on their noise rating. I did this for my self-built machine last year and never regretted spending the money on new drives and new fans. It's SO much quieter! ;)
