Hello there, I'm wondering if someone can identify the issue I'm having with a "screeching, white noise" sound I'm getting when my computer shuts down or restarts. It seems like the moments after it completely shuts down, but before the power supply has turned off (maybe a full second, prob 1/2sec) I'm getting this crazy screeching, almost scratching sound blaring out my speakers. I have both a HDD and a SSD but suspect the HDD since it spins and what not. Is this sound I'm hearing coming from my hard drive? If so, is that bad? Thanks!
