Solve : Strange Noises on Start Up?

Answer»

I bought my computer new in early August, 2008. I've had it eight months. It's an HP Pavilion desktop with an AMD Phenom 9500 Quad-Core Processor. It has two 350 GB hard drives. The operating system is Windows Vista. It has worked very well until just recently. The last couple of days the computer has been making some strange noises. It only happens when the computer boots up or when it wakes up after being asleep. Otherwise, it's as quiet as ever. What can be the problem? It's under warranty. Do I need to take it in for repair? The noises are pretty loud. Kind of like a rumbling. They stop after the computer gets going.

Thanks for your help!
VickiHi! have you cleaned your system..... shut the system down and pull the side cover off your case....look at the CPU cooler for dust on the fan and heat sink....also check to see if dust is on any fan(s).... if so.... purchase a can of air (follow directions)..... use the air to clean all I mentioned.... also could a bad fan.... so start up the system when cool and listen and look to see all fans how the fan or fans are working..... good luck!!! Does it sound like its coming from the disk drive?Sounds like a flaky hard drive...download HDD HEALTH and scan your drives ....you may want to start backing up anything important.

http://www.panterasoft.com/Karnac, as far as I can see, HDD Health has no options for scanning a hard drive, plus it's a beta program, a poor choice for recommendation.

Vicki, your hard drive is probably fine. Dying hard drives tend to click, not rumble. What you're describing actually sounds like a fan that is dirty, and not a failing hard drive. Let's try to locate where exactly the sound is coming from before we make any more assumptions.

Remove the side cover of the computer and sit in a position so you can see inside the computer when you turn it on. DON'T TOUCH any of the internal components when it's plugged in or turned on. Just get familiar with the location of any fans in the computer. There should be one on the motherboard attached to a piece of metal (processor heat sink) and one at the rear of the case at least. There also might be one in the side cover you removed, the video card, or even in the lower front of the case. Once you've FOUND them all turn it on and listen for the sound.

Once you've located the sound, shut down the computer, then replace the cover. Let us know what you find.

Can't believe I forgot to mention there might be one on the video card. I don't recommend you stick your finger into any of them either.My graphics card fan used to do that, make a growling noise at start up then settle down.
I opened the side up and gently touched it, that's how i found out what it was.
Stopped doing it now.

Lol^

I think that your rumbling noise is coming from a fan that's spinning too fast or too slow at startup.It was new, my mate had the exact MODEL i had and his did the same, it was as though it needed to 'balance' itself.Quaxo, thought I said this on the first post...... Good to see we are on the same track.....I forgot the Vidcard fan too.... hope LouisiannaGirl gets back to us Thanks so much for reading my post and writing all your comments. I really appreciate your willingness to help. I know it's important to give as much information as possible when asking for help. I forgot to mention that I know how to use a computer, but I do not know how to remove the case and look inside. I'm afraid my PC would really be in bad shape if I attempted that! I know my limitations.

Today, when I started up my computer, it was really quiet. I was amazed because I had been worrying about it. It has been running now for about 30 minutes and is almost totally silent. If I get close to the tower, I hear a faint noise like any working machine might make.

Thanks again for your replies. I will keep you posted if it goes back to making that noise.

This is not a forum just for advanced computer users, is it? I sometimes need help with my computer, and I am thankful for all those people in cyberland who have the experience and knowledge to help!

Have a great rest of the week!

Happy to hear from you..... This site is for all LEVELS of computer know-how..... As far as knowing about your case.... just take the left side panel off.... sometimes thumb screws or a latch...whatever!.... look inside.... you can't messup anything as long as you DO NOT TOUCH THE INNER WORKINGS... static and all that.... It sounds like your system needs a good cleaning.... dust is a system killer.... over heatting etc.... you'll do just fine..... Good Luck!! Quote from: LouisianaGirl on April 08, 2009, 05:33:14 PM

Both! members can both seek help, and if they believe they can offer advice to others they can do that as well!

Everybody is welcome.


Robit, If she's not comfortable removing the case then we really shouldn't be pushing her to do so; although it does sound like a possible dust issue.Hi PC_Programmer: your point is well taken, however she should know if nothing is done a bigger problem could ac-cure..... perhaps it will be a learning experience and all participants in this forum know that these are suggestions.......LouisianaGirl, it's understandable if you're not comfortable opening the side of your computer. Honestly, there's not much damage you can do in just opening the side, so long as you don't start poking your finger or screwdriver into things.

However, if you're not comfortable doing so, is there someone you know who might be able to check for you should the problem occur again? It might be a good idea to do it and also have the innards cleaned of dust. A buildup of dust can cause heat issues over time. Some computer repair shops can do this for you as well.
