Question How do I fix my frame drops/stutters and also improve performance ?

[LEGENDKMS7]

This is my brand new PC
CASE - Lian Li 011 Dynamic Evo XL
CPU COOLING - Lian Li Galahad II LCD 360 AIO
FANS - Lian Li Uni Fan SL120 V2
MOTHERBOARD - ASUS ROG MAXIMUS Z790 FORMULA
GPU - ASUS ROG STRIX 4090 OC BLACK
CPU - Intel Core i9-14900K
POWER SUPPLY - Dark Power Pro 13 1600W
RAM - CORSAIR Dominator Titanium RGB DDR5 RAM 24x4 7200MHz CL36 (Using 6000MHz)
SSD - Crucial T700 4TB Gen5 NVMe M.2 SSD x3
OS - Microsoft Windows 11 Pro
Monitor - LG 27'' UltraGear OLED Gaming Monitor QHD 240Hz 27GR95QE-B
Mouse - Razer Viper Mini Signature Edition
Keyboard - Wooting 60HE

Every time I game, I get random frame drops and stutters. My PC would drop to 1-5fps and freeze for 1-10 seconds before running normally again. I thought it might be my increased polling, so I lowered it to standard, but I am still experiencing issues. I want to increase my polling rate, but I would rather have a perfectly running PC over polling.

I am running Overwatch, Apex Legends, CS2, Valorant, and COD.

Everything is up to date. I updated my bios and ran stress tests. I ran Cinebench for 2 hours, and The highest temp was 101, the minimum was 36, and the average was 74. My temps look fine, and my resources stay below or around 50%. I tried undervolting, thinking that might help, but it gave me too many issues, so I put everything back to default. Can someone please help me fix this issue? I also want to increase my performance if possible.

Uneven mount pressure is what I was thinking. You can use the Intel XTU program to limit the power the CPU used to 125 watts, which is the base power of the CPU.

I reseated the AIO and reapplied the paste, but there was no change.

Edit - I also replaced the CPU with another 14900k, but I still have issues.

Hello,

You may wanna check my recent troubleshoot (the last message):

That's how I fixed my system struggling with same kind of issues.
And of course, make sure your drivers and BIOS/UEFI is up to date.
Check this too on WIN11 'Optimizations for windowed games' >> disabled.

By the way, insane build, you should be doing great with that.. 😀

I tried to follow your steps, but it did not help. Thanks anyway.
