Unresponsive or freezing during usage

Hi guys, I have been using manjaro gnome for close to 2 years now. Love the platform and support. Generally speaking I manage to get by small issues by googling the solution but I have been stumped lately. As of like past 4 months my laptop keeps freezing and becomes unresponsive forcing me to restart. I mostly use this for browsing light text editing work. I am currently using firefox as my browser an another problem is playing videos while streaming the video will get stuck and having read a small fix which is to use the volume key which somehow makes the video keep rolling. But the main issue is every 2 hours or so no specifically my laptop will fully freeze.

Below is my system details:

Ok guys i noticed that my report above showed that my swap was not active, and tried to turn it on following the wiki.manjaro guide and added the following codes on my terminal

sudo swapon /dev/sda2


sudo bash -c “echo UUID=$(lsblk -no UUID /dev/sda2) none swap defaults 0 0 >> /etc/fstab”

Now i have a new problem. Takes almost like 2 mins to log in and just before i get logged in I get the following errors

Timed out waiting for device /dev/disk/by-uuid
Dependency failed for /dev/disk/by-uuid
Dependancy failed for swap
