Hi,im not very good at computer. For the past few days my computer has been making this high-pitch sound which is driving me totally insane!. I have no idea what is making this sound and i am definitely sure it is not caused by my fans as i have tested them all, its not my Monitor either. Could it be my PSU?, CPU?, Motherboard?, GPU? i have no idea so please tell me what to do, thanks!

Oh and here are my specs

PSU: Cooler Master UCP 900W
GPU: Nvidia GTX 285
Harddisk: 1TB SATA HDD
RAM:6GB ddr3 1600mhz

More details needed...

Is your computer running fine otherwise when you hear the sound? Is it a continuous high pitched noise? Does it occur as soon as you boot up?

There is usually either a small speaker attached to the case (usually the bottom) or a piezoelectric one on the motherboard. You can easily determine if one of those is the source.

Another possibility is the hard drive, which should also be fairly easy to determine. If you can't tell, it might be necessary to disconnect it temporarily.

Those are just the more common ones (if you're sure it's not any of the fans), but it's hard to say without actually hearing the sound. Post back if you need any further help.

Find it...

Just follow your ear to the source of the noise. Its basically telling you where it is. Remember fans are in the PSU as well. To quickly check that, with power-OFF see if the fan moves easily with a prod to include any other fan(s), don't guess check it out. Now a "squeal" of sorts can be a "electronic component" but its that hard to find if small and such, but again your ear is the best clue. Last, the only other source of noise is the drives as they're constantly ON. If a bearing is starting to go, then with power-OFF unplug a drive and then power-ON and check results. I don't suggest that for a fan as fans are too critical for cooling, but that's up to you. good luck
