Getting terrible FPS out of the blue.

I'm using a geforce rtx 2080ti. My CPU is an Intel i9 10900f. 350w PSU. 32gb of ram. For some reason today out of nowhere my frames dropped to around 20 today. Usually I get around 100-144 depending on the game. I updated my driver and I'm still getting terrible performance. My resolution hasn't changed I'm still playing on 1080p. I'm so lost on what to do. I've never have had this issue before. Was playing Black ops 6 perfectly fine. I get back on a couple hours later and my performance took a massive hit. Tried playing a different game that has always ran at 144 fps for me. Even that game as well was running at half the speed. I don't even know where to begin to try and fix this issue? Any suggestions would be appreciated. Has my GPU just ran its course or is there anyway to troubleshoot this?
