Question I think my CPU is causing the GPU to drop frames to between 0-5 frames while gaming or video editing ?

[gamerNoVisual]

Just recently my PC started experiencing lags and stutters. I tried playing a game and started experiencing massive frame drops after an hour or so.
The CPU and GPU temperatures look good so I'm just wondering what else could be causing it?

MotherBoard: Asus TUF Gaming Z690-PLUS WIFI D4
CPU: 12th Gen Intel Core i7-12700K, 3600 Mhz,
GPU - Nividia Geforce RTX 3090
RAM: Neo Forza Faye 32GB (2 x 16GB) DDR4-3200 PC4-25600 CL16 Dual Channel
PSU: got a new one this year which has been working well.
