Question Windows is too laggy ?

[xDeluxers]

I have a problem with my PC.
Every now and then while I play GTA, randomly my PC starts to lag and the game starts to run at 2-5 FPS and the GPU only uses 10%, if I go back to the desktop, Windows it goes jerky, watch the video at the bottom.
I tried reinstalling the GPU drivers with a clean install via DDU, but the problem persists.
Would anyone be able to help me please?

Check cpu/gpu temperatures.
Use MSI afterburner.

What cpu cooler are you using?

In the video you can see the temperatures in the upper left corner, however the temperatures are approximately 72ºC for the GPU and 53ºC for the CPU

I use the stock cpu cooler of the Ryzen 7 2700x (AMD Wraith Prism RGB)
