[SIZE=2]So two weeks ago I noticed this whinning noise coming from the power strip of my computer. It is odd that my printer's adapter/power strip makes the same very high pitched noise also. Older people are not even able to hear this noise but at points with no background noise it is very annoying.

Any way about a week after noticing the nosie my computer failed to turn on so I figured the power source had a failure so I got a new one, a CORSAIR GS800, so a 800 watt source the same power amount I orignially had but a much better brand and quality at least I think.
The computer runs fine, without any problems. However when the system is shutdown I hear this lite crackling noise, it is hard to explain but it is there. It is an electricty type sound. When I turn the switch from on to off on the back of the computer the noise goes lower. However the noise only shuts off completely when the system is unplugged or the surge protector is turned off.
Any ideas? I heard I should try to unplug different components inside the system and see if the noise stops with one of them off and that could be the problem. However I am not comfortable with unplugging things inside my computer as I have no idea what I am doing with hardeware. If it is some type of componenet such as the video card (man I hope not!) does this need to be replaced? Or can it be something is out of line. I have already dusted the inside and all the vents. Is it difficult to unplug different components I have opened the case and gone into the computer etc.. Just so many different wires etc.. Have no idea what each does.

Thanks for any info. It is just wierd that the orginal power source failed and now this brand new one is making a bit of a strange noise but not the same as the old one.

1. I have heard the whining noise you describe from lots of different power adapters. Young folks such as yourself can hear high pitched noises better so you may just have to live with it until you can collect Social Security. You could try buying other adapters but they may make the same noise.
2. Have you tried it on different outlets or with different power strips? I am no expert on electricity but maybe there is something wrong with one of those.
3. How did you put in a Corsair if you aren't comfortable with hardware?

My parents said the same thing. But today the noise coming from the computer seemed louder and my mother was able to hear it. It is not a high frequency noise this time. I have tried different power strips, power cords, outlets for the power strips and plugging it right in the wall it is the same sound no matter what. And it just does not seem normal.
I did not install the new PSU, I had someone come in and install it for me which was pretty reasonable rates so will probably have him come in again and troubleshoot the system for me to see what needs to be fixed. Maybe watch and learn some more about the hardware of my computer. I am sure it is not too difficult but with the money spent on this machine I do not want to mess something up at least for the next few years until its time for another one

Try using something to stop the CPU fan and other fans and see if the noise stops. A wooden or plastic stick is good.

CAUTION! If you stop the CPU fan don't do it for very long. CPUs will heat up quickly and can fry if the fan is stopped for too long a time.

It won't take but a fraction of a section for you to realize the noise is coming from the CPU fan if you stop it so you shouldn't have a problem.

Well I do not know if the noise is there when the fans are running. However the noise is there when the computer is off and the fans are obviously not running during then. Thats the problem. I have a guy coming over to the house today to help me troubleshoot it to see what is wrong with the computer.
