I'm a new Linux user and everything has been working very well for me except one small issue. I am getting random stutters infrequently that I cannot diagnose.

The stutters last only 1 second, and if I am playing a game the framerate drops and also the audio stutters. This also happens when I am not playing games, just browsing the web or listening to a podcast. 99.9% of the time the system is very responsive and runs better than windows ever did. The stutter happens maybe once every 2-3 hours it seems, they are rather infrequent.

I have tried watching the system monitor to see if memory or CPU usage is spiking but I haven't noticed anything strange so far. I thought maybe it could be an issue with one of the disks but I don't know how to determine that.

Since I am new to Linux I am not sure where to start to even begin to figure out what the cause is. So any advice or even basic tips would be very much appreciated. Thanks for the great OS!

Hi there, welcome to the forum!
The one below is a very detailed guide. I hope it will help!
