Micro stuttering, buzzing from pc, and frame drops.

[Dummy]

I just built this pc back in the beginning of March and it’s been working great till about two days ago. It’s started freezing for half a second and stuttering on games that used to run perfectly fine last week. On more demanding games like red dead 2 it used to run smoothly around 90-110 frames but now it’s dropped to 40-60. Even when I set it to medium or low settings these drops still occur(Tho not as severe). Along with all this is a buzzing sound that’s gotten progressively louder over the course of a month when I’m playing a game. I don’t know where it’s coming from and just assumed it was coil whine from the gpu. I’ve checked the temps and nothings overheating when I’m playing. Earlier today I even took everything apart and cleaned it for dust and still the problem consist. This is my first build so I’m still new to all this and any help would be appreciated.

My build
Cpu: Intel core i9-9900k
Gpu: Nvidia GeForce RTX 2080 ti 11gb
Psu: Evga 850w GQ
Mem: CORSAIR Vengeance LPX 16GB (2x8GB) DDR4 DRAM 2400MHz C14
Mobo: Maximus XI Hero Z390 (not sure if motherboard matters but figured I’d add it)

The buzzing is coil whine. There's not much you can do about that and it's not considered a defect under warranty by most sellers.

Make sure drivers, BIOS, and windows are up to date.

Also, you'd get much better frames per second if your RAM was at least 3000 MHz, 2400 MHz is way slower than what you should be running with that CPU+GPU.

Everything's up to date, I checked my temps while playing and my gpu and cpu are in the 40-50c range so I don't think its a heating issue. The games run fine and look great there's just sudden frame drops and stutter happening every couple of seconds that never used to occur.

Get DDR4 3200 CL14

Does having lower mhz make the situation worse over time? What I mean is why did it take two months for these problems to suddenly appear.

No, it just means you're going to get slightly (and I do mean slightly) less performance.

Have a look to see what your temps are, see if you're throttling.
Make sure all heatsinks are clean.

Are you sure all drivers are up-to-date?

Have you tried reinstalling GPU drivers (or DDUing)?

Could you discribe what the buzzing is like? And where in the PC it's coming from?
(You can use a tube from kitchen roll or toilet roll to isolate areas to listen if need be.)

Unless your speakers have a loose connection or a ground loop, or maybe a loose wire that's too close to a fan, buzzing is probably a bad sign.

is the oc stable?
can it pass an hour or more of ibt or prime95 small fft?

I just tried the ib test on maximum and it said it was fully stable, never went above 50c.
