System keeps freezing

Hey. I have this problem where EndevaourOS keeps freezing after a while of playing. I’m on the LTS kernel (a topic on here suggests using the LTS kernel to prevent freezes, but guess what) with the GNOME DE suite (means that I fully use the GNOME suite that is the GNOME DE, GDM is my display manager et cetera).

What do I do?

Swap undefined?
