I am extremely sensitive to high pitched noises, and my computer has started making one that is driving me insane. It is very slight, and i can only hear it from certain angles, but it is defiantly there and It will not go away.

What I have tried:

restarting the machine (the sound went away when it turned off)
blocking every fan for a few seconds to see if they were making the noise (they are not)
Tried listening for the sound with a tube to isolate the part making it (didn't help since tubes don't bounce sound very well) Though i did find which area the component is in.

I believe it is a part on the board making this noise, and that is making me even angrier since i do not understand how or why a part on the board can generate such a sound.

Can anyone assist me in fixing this, I know there was another person who had this issue before, but his went away magically. Hopefully mine does too, but I wouldn't count on it.

if it matters, I am using a Foxconn Blackops board.
 
Now the issue has slightly changed. I removed 2 small fans on some racks for hard drives and the high pitched whine has stopped. But now there is a similar and possibly related problem.

now i hear a slightly quieter, very rapid series of beeps.

I cannot make this stop and it is literally causing me pain.
 
i have no clue what the beeping sound would be from.. but you are better off buying a completely insulated case.. should stop most of the noises from being heard..
 
I don't want to have to rebuild my entire machine to get rid of this noise. There has to be something causing it and there has to be a way to stop it.
 
If you could give the spec on the whole system we might could advise better. There are know issues with certain powersupplies and SLI setups and also certain dual gpu cards causing whine/beeps.
 
It is probably a fan on your motherboard. I have had a similar issue before the fan died.
 
Check each fan. Stop the fan by slowing it down with your finger or something (push against the center of the fan, instead of trying to impede the blades) to help narrow it down. If its electrical noise, try to listen to where its coming from (typically the UPS, but could be something else).
 
Ok, i believe the issue has been solved by foxconn tech support.

apparently there is an alarm that goes through the on board speaker to notify me if the fan speeds get too low. I shut that off and it seems to have stopped the noise, but i am not entirely sure.
 
yea, my best guess is something is causing your video cards to over heat, causing there fans to sound like that. I had a similar problem on my old rig, I just installed a couple more case fans, which greatly reduced the noise output.
