PC made weird rattling noise, now everything is stuttering

[trini]

Alienware prebuilt PC, RTX 3090 with an i9 11900.

The only way I can describe the noise is that it sounded like a rattlesnake, one of those bugs you hear at night time, or the sound you get when you wind up a wind-up toy. Nothing out of the ordinary is visible when I opened up the PC, but now all my games are stuttering and some won’t even open. When I went to shut it down, Windows forced me to update it so I don’t know if the stuttering is a result of the forced Windows update or a result of the rattling noise. I’ve tried Googling and can’t find anyone who had a similar problem.

What the heck happened?
