I just moved from Windows 10 to Ubuntu 22.10 on my HP Notebook - 15-ay542tu laptop which has
CPU: Intel i3-6006U CPU @ 2.00GHz
RAM: 12GB RAM
400 GB SSD (ubuntu installed here)
1TB storage disk
Problem
The system freezes randomly for a minute or two and comes back online.
- It used to happen even on windows (but there were so many bloated softwares running, therefore I thought high CPU usage was the problem).
- The frequency of freezing increased on Ubuntu than on windows (contrary to my expectations). On windows, it used to be 2-3 times in an hour. On Ubuntu it became 8-10 times in an hour while I only just webbrowswer with 7-8 open tabs.
My conclusions so far
- I think its not high CPU usage or insufficient RAM/Swap:

- I think its not SSD or storage disk
What is it then? I am clueless. I don't know how to zero-in on the cause of these freezes.
No. of freezes are more on ubuntu than on windows
EDIT: Now that I've been using Ubuntu for 2 days. I noticed that no. of freezes have increased phenomenally on Ubuntu. I have no clue why. System resources are consumed less on Ubuntu but freezes are more when compared to windows.
I don't know if its relevant but at the time of booting i get this message before login screen is shown
Also today morning system crashed and showed this error
EDIT 2: When I run from live usb there are no freezes
I tried running Ubuntu live from USB (without installing) then there are no freezes. This immediately makes me think that the SSD on which ubuntu was installed is at fault. But I don't see any errors in SMART data.
What could be the issue? Is it the SSD that might be causing these freezes? What should I do now. The disk is still under warranty

for very long. Do you have a lot of USB devices (particularly USB storage devices) that are active at the same time?iotop
should give you the basics to identify what your system is spending so many resources on 👍🏻
