PC making high pitch when turned off and sometimes when turned on.
1 replies, posted
So i just built a new PC 3 days ago and as soon as i plugged it in i hear a faint high pitch. now i don't really mind that, but when i turn on my PC the sound gets louder and won't go away. If i want it to go away i have to turn it off. wait a few seconds, turn it on and if i'm lucky the sound won't come back. this is really frustrating and the noise is making me go insane! help would really be appreciated!
Coil whine, most likely coming from the PSU.
It doesn't mean anything is broken/will break soon, but yeah it can be pretty annoying, you might even be able to RMA it because of that.
