Author Topic: [solved] continuously cycling noise on one computer but not on others.  (Read 1551 times)

I am running VL 6 KDE Classic on 3 computers in my home.
It works just great on all of them but this computer has an annoying noise that is continuously recycling every second.
The sound is like a rising falling buzzy tone.
This is not happening on my other computers and so very annoying.
This computer is an HP Pavillion AMD triple core with 2 320 gig hard drives and 3 gigs of ram.
One other that is quiet is an HP dual core with 4 gigs ram and 320 gig HD.
And the other one is an AMD Athlon with 1 gig ram and 100 gig HD.
I notice that the HD lite is close in sequence to this noise. In other words the HD lite shows in similar relationship to the noise.
I tried shutting down the swap but that made no difference.
This same type of noise is prevalent during boot up as the HD lite is mostly constant during boot.
The noise is not from the fans or power supply.
What othe rinfo do you need to help me?
I don't want to use a different Linux OS.
P.S. this noise seems to happen with all the Vector 6 versions.

Edited to indicate [solved].

If the noise is associated with hard drive access, I would recommend running a diagnostic on the drive. I use the "Ultimate Boot CD" (http://www.ultimatebootcd.com/). Find out what brand your hard drive is and run the appropriate test from the boot menu.

If it's what I'm imagining, I keep thinking it's some kind of electrical "noise" that's coming through the speakers. I have "noise" come through my HP laptop (old model) when plugged directly into the outlet. I end up plugging the three-pronged power adapter plug into a 3-to-2 prong grounded adapter and the noise disappears. Although not a perfect solution, it works for me, but it may not work for you. If you have an adapter then it might be worth a shot (note: I don't actually do anything with the screw hole).

Well; there are few more things I know now.
This sound is not coming through the speakers.
It is not from the drives either as I have removed these drives and installed an old 80 gig ATA drive and installed VL 6 kde classic.
the noise is still here.
The HD lite is still flickering on and off. Not perfectly in time to the noise cycling.
I have a hearing problem and use two hearing aids so am not able to focus on the noise source.
Trying very hard I think it might be coming from the CD/DVD drive.
Odd! I think I will try swapping it out for another one and see if I get any closer.
Thanks for the responses and ideas.

OK! I have removed the CD/DVD drive and the noise is gone.
I don't have a replacement as it is a SATA drive. 
Guess I will have to go get another one tomorrow.
Thanks for the help.

Excellent troubleshooting.  Smiley

At this point, it is a good idea to edit the original post, adding [solved] to the title.

Actually it is not solved. I bought a new CD/DVD burner and after running it a few days the noise started up again and it is even a bit louder with the new CD/DVD burner.
Since then I have gone back to VL-6 GOLD and with either CD/DVD drive there is no noise.
The noise does not happen when I run any other Linux distribution. It only appears when I run VL-6 KDE Classic.
I am now sticking with VL-6 GOLD but am curious about the reason for the noise on VL-6 KDE Classic.
P.S. I loaded KDE into VL-6 GOLD so it is almost the same as VL-6 KDE Classic. Still no noise!

All I can think of is that there is a polling daemon (like HAL) involved when the noise is present.

I guess it is not HAL.
I reinstalled VL-6 KDE without using hal and that changed nothing.
The other thing is that this only happens on this computer. Not my HP laptop or my older pc my wife uses.
All are using AMD cpus.
This on has 3 cpu the laptop has 2 and my wifes has single.
Those last two both have VL-6 KDE Classic installed and running {quietly} .

Thanks for the reply.
