Discussion Weird Noises when booting up pc

[Monster.]

Hey so last night when I turned off my computer by just unplugging it since I was in a rush,it suddenly made weird noises when I boot it up the next day and one of my case fans started to spin very slow im not sure if its that or my hdd or I need to clean my pc since Ive been using it nonstop during quarantine.The sound it makes is like a hdd starting up but continous and loud,Im really worried about this.Thanks in advance

Well you have to check every part of your systems then. Never turn off computer by unplugging it.

I know it was my mistake but the solution i found was cleaning my case fan which stopped the noise but now when I try to boot it up it turns off and on witht the case and cpu fans

Do they are all not spinning on boot ? try check your psu first using paper clip. Your can find the tutorial on youtube.
