CPU/GPU bottlenecking when playing games

I have a Ryzen 3700X paired with an X570 gaming edge motherboard and a MSI 4070TI Suprim. Out of nowhere a few days ago most games have been unplayable due to insane lag. My main game I play is Call of Duty BO6. Up until a few days ago I consistently have ran 144 fps and have never experienced a single FPS drop. Now My FPS will go from ~140 down to single digits and then fluxuate from the teens to 100. My CPU is running at nearly 100% and GPU seems to only hover around 50% usage. I've set everything to maximum perfomance settings to try and force it to pull from my GPU. I didn't download anything different. I tried lowering the VRAM in the game and all of my visual settings are set to about as low as they can. I ran MSI afterburner to watch it while I was playing to confirm the numbers. All drivers are up to date and I even tried rolling back and downloading an old driver only to have the same issue. I tried multiple games and am experiencing the same thing across multiple games. I can't help but think its something RAM related, but I was wondering if there was anything else I could try to fix this issue.
