Warzone inestability

I recently upgraded my motherboard (MSI MAG Tomahawk X870), CPU (Ryzen 7 9800X3D), and RAM (G.Skill Trident Z Neo 6400MT/s CL32, 32GB), paired with a Zotac RTX 4070Ti GPU. Since the upgrade, I’ve unfortunately been unable to play Warzone. My computer completely freezes after some time in a match. I’ve noticed that the FPS in-game spikes to 270 but then drops to 110 almost instantly, making them highly unstable. I suspect this might be causing the freezing, but I’m not sure where the issue lies. I’d appreciate any help.

For context, I don’t have this issue when playing Black Ops 6 multiplayer or any other game. Currently, I’m playing God of War Ragnarok with all settings on Ultra at 1440p without problems.

I hope someone can help me troubleshoot this issue.

Thank you
