I am having problems with Linux on my PC. I am facing issues with CPU usage I believe. The issue persists with short CPU spikes causing my PC to freeze for short periods of time, around 1 second. And this happens pretty randomly. Watching YouTube or a movie using VLC, using a code editor such as VS Code, or doing any small task while nothing else intensive is happening in the background causes these short CPU spikes. This also happens on the latest Ubuntu LTS release, same exact issue. If you look at the CPU History of the image below, where ever there is a bigger difference in the workload of the CPUs, that is when the PC freeze kicks in enter image description here

Here is a inxi -Fxz dump of my system:

I have no clue what could it be except for driver issues.
