Afternoon for weeks now there has been a high pitched noise coming from my PC. It is like a dog whistle and has caused ringing in my ear. It occurs when windows is loading not before and then remains in idle or full load.

I have removed all graphics cards, ram, hard drives one by one testing for the noise. Changed all case fans / cpu fans for silent ones. PSU when removed from case and used doesnt make the noise. I was in the process of rma for the motherboard, used my friends spare and still the noise would occur as it seems to be coming from the cpu chip (i have changed the heat sink and fan but still the same noise)

Ive tried turning off all cpu bios settings to do with energy saving / efficiency - still the same noise. I'm pretty much left with only the cpu chip left to change which will need a rma but can a cpu chip make a high pitched noise that is so damaging i cant keep it on for more than 5 minutes ?!?!



Model Name : GA-Z68A-D3-B3(rev. 1.0)
--------------------------
M/B Rev : 1.0

Antec ultra silent 650W power supply.
 
Yeah sorry I've got another PSU coming to replace it as a last desperate move, but I did turn on the PC with the power supply connected up but outside of the case and the noise still appeared to come from within the case !

I always assumes that a cpu chip itself cant make noise right but the noise can be an intermittent high pitched within a continuous general ring ?

But then the noise has caused ringing in my left ear for days now so it isnt easy to tell but Ill see if another PSU works .. the original one only being 2 months old :( Ive read about coil whine which is my only hope now but the fan on the PSU is silent.
 
ahhhhh the high pitched noise at idle oh how i use to love that on my old system

if it is what i am thinking it is try disabling c-state and C1E in the motherboard bios

from what i have been told its doggy capacitors on the motherboard

I've noticed since getting my passive watercooling setup that intel's chipset is rather loud when ever there's any hdd activity, I've also upgraded my motherboard since as well from a p67 to a z68 and that's no different so yep some chip designs out there are rather poor for acoustics. It's just like fixing a rattle in a car, you'll be able to hear a slightly quieter but just as irritating different one :D

I suspect if its quite loud though it's more likely to be a capacitor on the motherboard as smithy83 said or in the psu but unless its just taking a moment to start doing it after powering on from cold I wouldn't have thought it's the psu because it wouldn't be affected by windows loading, if you restart windows does it stop doing it after windows has shut down but before it loads again?

tried clean install of windows? its either psu/gpu related and it interferes with the poswer saving of the mb,use latest bios aswell

can be driver problem too
 
Noise is the same on two motherboards so definitely not that. Tried the disable C states on the new motherboard etc. Reinstalled windows twice on different hard drives ... removed gpu and used only igpu off chip and still sound.

I really dont think its the psu but i will replace it next but the only other component is the cpu as ive changed the cooler and heatsink. Thanks for replies and will see what happens with psu change but ive never had any thing like this in 15 years of pc's and if it is the cpu i will be livid with all the other components ive changed.
 
99% of the time its psu,it can be gpu but psu is more likely,top end and el cheapo psu's all can produce the noise so its a bit of a lottery to which ones dont make the noise

its very common issue,i went through it on my x58 gigabyte board,changed psu and noise went

EDIT: are you running gigabytes dymanic power saver or easytune? ifso try turning them off and see if noise goes away

im now on a newer asus board (last 2 days - Asus P8Z68-V/GEN3 S1155 Intel Z68 DDR3 ATX) which hasnt made a difference even though the bios had a lot more settings to disable cpu power saving options - still same noise. I think maybe i just dont want to accept the 70 quid PSU after 2 months is a duffer !

But before on the gigabyte board easy tune was installed although it was all on stock settings / default.
 
well im on a z68 asus v pro(nongen) using a 5870 and no noise at all,its silent

cant mention psu make as its a mid level competitors brand

Click to expand...

I did a build for an office pc at work with a corsair builder series psu and that did it horrible :mad:
 
Right lads im in real trouble ... got a new cheap psu and a silent cheap gpu with heatsink only off my mate and it is still making a high pitched noise !!!

the only item i havent changed is the cpu chip now which it has to be, this is insane !
