so i'm not sure if i should post this here or not but here i go anyways. i recently built my first computer. everything's working well with one exception. every time i shut down my computer, i get this weird screeching sound for a couple of seconds before it powers down. i changed the speakers and i get the same sound, i even changed the ports from the case to the motherboard audio jack and i get the same noise. i even reinstalled the audio drives for my asus M5A97 R2.0 mobo and i still get it. is the build in audio chip not good? i get fine sound when its on but when it turns off, i get that screeching noise. would buying a sound card fix this? what does it look like the problem is?
 
Solution
A new sound card should fix it

Some of those on-board Auto Switching Sound Cards do stupid things when they power on/off and new plugs plugged it can make all sorts of weird noises.

Is it coming from your speakers or do you not know? I have had case fans make loud noises as they have come to a stop... Might try unplugging them one by one and stopping it to see.

I have also experience something similar to this your options are:

Turn off your speakers first or turn down the volume
Plug your Speakers into a Different Outlet / Power outlet

Some powered speakers are very sensitive to power fluctuations

it comes out the speakers. i even used headphones and i could hear it. im guessing its the built in audio that may be to blame.

i hear it through headphones too from either audio jack. would getting a sound card possible fix the issue?
