For the past couple of years, my computer has been making a high-pitched hummming noise when it starts up. The computer will not start up for about 3 min then all of the sudden it will boot up and work normally. I'm not sure what this is. I have checked to see if it was the software installed, my RAM, my fan, or my video card. It was none of them. I will try to post a recording of it if I can get it again. Any ideas as to what this may be would be nice.

 

 

Thanks

What's your internet connection? 56 k?

what does that have to do with it?

 

try checking the Processor and it's fan it could be that.

Do you remember the screaching sound that dial up made?

 

Could be processor fan with something stuck or something

True check the processor.Try to remove the fan attached on the top of it and clean up everything from dust and ect. You will sure receive benefits at least from the cleaning as dust is the worst enemy of chips.

yeah but that awful sound wouldn't be from Dial Up not BEFORE the computer is switched on and the connection made.

Well what do you think the sound is?  . Running off a sound isn't very detail and could be any number of things

 

He says it's not the software installed, RAM, fan, or video card

 

Assuming he's right, and he did checks properly.

 

I'm going to guess Floppy or Cd/dvd rom drive has something loose as you can hear those things spinning at start up

Maybe.

Have tried to have your computer opened and stay near it when start to try to indentify where the sound came from?It's just an idea.

my dad who repairs pc says to do what lord of the sith suggests and try and find the location but he says it maybe that your CPU's fan maybe catching something.

Lol, I repair computers for School and library, but really online help isn't the best.

 

Once again you guys, he has said  "I have checked to see if it was the software installed, my RAM, my fan, or my video card"

 

so that cpu fan maybe catching maybe irrelevant because he already checked it.

Ill post my specs, keep in mind that 6 months ago I was given this computer from my dad, and it still had problems then. The wireless has nothing to do with it.

Im not sure how to find my motherboard model or the ammount of voltage my power supply has...

my older computer has problems too, it has an allergic reaction to video games 

Is it even slightly possible to get no spamming from you for once chesse?  ;D

 

SPAM SPAM SPAM SPAM SPAM SPAM SPAM SPAM SPAM SPAM SPAM

 

 

 

FACT: did you know spam is also a fake meat?

 

ALL RIGHT, BACK ON TOPIC!

 

I switched from my integrated sound to my sound card and I havent heard from it since. (at least from what I remember) Could it be that?

it could be... but seriously that was the last thing on my mind to check.

Thats the only software I didn't check (besides xp itself) I mean, seeing that a did a Guttman 35-pass technique to wipe the hard drive, you would think it would be a hardware problem. I'll keep an ear out to see if it does it again. Ill switch between the two drivers for a couple of days to see if it does it anymore. Feedback on other problems it may be would be nice, just in case the audio drivers aren't the case.

Before xp starts it's typically almost all hardware based sounds. It could range from floppy disk to processor fan.  Most sounds are lower pitch because they are spinning parts in say the cd rom, high pitch could just be your computer. However assuming it wasn't like that, it is an error. Good luck

I'm thinking it my be my power supply but I don't know how much voltage it can take...

Erm well there should be a label on the power supply its self saying what it is if not just explore the system tools and see if you can find it.

go to bios to play with powersupply, much safer

ya know what's weird? my walkman does the same thing, when my sister got an ipod she let me have her walkman and for some odd reason it makes this whiiiiiiiiiiring noise for about 5-8 seconds then it will turn on and work normally, The same thing happens when I turn it off too, it goes whhhhhhhhhhhiiiiiiiiiiiiiiiiiirrrrrrrrrrrrrrrrrrrrrrrrrrr.... then it turns off......weird

do you leave the disc in the disc drive when you have the pc turned off? it could be that?

where do you live exactly? I was thinking about my car in the winter and it makes a similar "whirr"type sound before the engine heats up. Could be just your enviroment

How do you do that?

Sometimes, but it has been doing it for 3 years, long before I started the habit of leaving it in.

I live on the west coast around Portland, Oregon.

Sorry for double posting...

 

I tried to record it when I started up my computer today but it was to high-pitched and the recorder wasn't close enough so I will try again :'(

enviorment shouldn't effect much, especially computers and walkmans. Unless of course you keep your computer outside 

 

When there is a problem with my computer I ask my dad who knows just about everything to do with computers and math stuff
