Solve : High pitch humming from computer?

1.	Solve : High pitch humming from computer?
Answer» Hi.. i got a problem and I've been checking online to find a solution to this problem and I haven't been able to. There is a high PITCH hum coming from my computer, and it also flows through my speakers so the higher the volume, the higher the high pitch sound gets.. and its GIVING me a headache. I unplugged the videocard/moniter and speakers yet the hum sound is still there. Even when i shut down my computer, I can still hear it, and when I unplug the cable from the power box to my motherboard the sound went away, also if i move the cords from that plug it stops/turns back on, so I'm figuring it has something to do with that but got no idea what to actually do, thank you.How old is the machine ? ? What make and model ? ? It sounds to me like that power supply COOLING fan is getting ready to go South. Give us more info and we can advise furthreI don't know the details of my computer but..its around 5 or so years old, I had to get a new power supply box a few years ago though. mother board is, Intel® Desktop Board D845BG - pentium 4, 1.6 Radeon 9600pro 512 RAM Intel 82801BA ATA hard drive Killer NIC Its a VPR Matrix, I think they sell them at best buy, or use to. its the 1620 model. I don't think its the fan because, when i turn the power off, the fan isn't on but it still MAKES the the humming sound. Also I dont understand why my speakers are transmitting the sound and I don't even want to raise the volume because its almost unbareable. I also had advice to put oil in for the fan, which I have never done but I don't think thats the cause either.. but then again you guys know more about this then me, thank you. If no fans are running and you still hear a humming sound you either have a short somewhere or that PSU is failing... Have you tried swapping in another one to see if the noise goes away ? ? If in fact it does turn out to be the PSU do yourself a favor and spend more than 20 bucks on it's replacement.

Patio < possible short somewhere ? Are you using the PC speakers or a 2.1 speaker system or larger ? Are your wires & speakers shielded ? Is everything plugged into the same SOCKET area or possibly a ups ? my bass is not shielded and had it running thru my ups with everything else, I simply unplugged the speakers from everything else and plugged in across room away from the computer. Try spreading things out first...maybe ?well the thing is, even if my speakers are unplugged, I hear the sound in my computer, its just my speakers are somehow picking up the sound and its coming out them, I figure since its probably the power supply, its picking it up from that. If the sound stopped after I unplugged the speakers I woulda figured it was the speakers, which is the first thing I did try to fix. My brother has a computer he dosn't use.. I guess I could use his power supply, I guess I could try using his. ThanksI don't think it is my PSU.. when I unplug the power cord from the PSU to my motherboard, while in shutdown mode, the humming stops, but my PSU isn't dependant on the motherboard so should be still on yet not humming and also, when I plug it back in the humming stops until windows is booted up and I open something.

Try another and see if it stops.I definitely have been given great advice and I appreciate it all, it's just with a problem like this it can be any number of things causing it, and I would like to do the most I can without having to buy or get new parts to replace things. Especially when your poor like me, I don't have money to go out and buy luxury things even if they are only 20 dollars.. and if I had to buy a new power supply I would want a good one because I bought a new one not to long ago and it was cheap.. and well look where I am now.

It sounds to me like that power supply COOLING fan is getting ready to go South.

Give us more info and we can advise furthreI don't know the details of my computer but..its around 5 or so years old, I had to get a new power supply box a few years ago though.

mother board is, Intel® Desktop Board D845BG - pentium 4, 1.6
Radeon 9600pro
512 RAM
Intel 82801BA ATA hard drive
Killer NIC
Its a VPR Matrix, I think they sell them at best buy, or use to. its the 1620 model.

I don't think its the fan because, when i turn the power off, the fan isn't on but it still MAKES the the humming sound. Also I dont understand why my speakers are transmitting the sound and I don't even want to raise the volume because its almost unbareable.
