Every 2-5 minutes, my PC hangs

My PC consistently hangs every 2-5 minutes. It acts like this since 2 days ago. How do I return it to normal?

Can you try rolling back to the earlier kernel and testing if the hanging stops?

How do I do that?

Reboot and when you see your Motherboard Splash Screen, begin tapping either left shift key, tab or esc. I give the "either" option because different users say a different key works.
This should show you the grub menu with Advanced Options for Zorin.
Selecting that will show you the option to Boot Zorin on Specific Kernels. You should see Zorin on 5.13.0-27 listed and Zorin on 5.11.0-46 listed...
Try the 5.11.0-46

It doesn't work. PC suddenly hangs while watching Youtube. I had to force it to shut down because it was repeating the audio, also the screen just hangs. :cry:

Are you saying that it does not work on the 5.11.0-46 kernel?

It did not used to do this, but began two days ago?

Ive installed Virtualbox a few days ago (before this problem).

inxi -G output:

Is this a notebook computer or desktop PC?

First thing I would suspect is over-heating.
During next freeze, try checking system temps with

watch -n 2 sensors

You may also check for errors on next freeze with:

dmesg -w

The output can be long - I recommend using Pastebin to relay that output here.

How do I make the terminal appear when the laptop hangs?

When it hangs, does it stay frozen until rebooted? If so, I would open a terminal and run

watch -n 2 sensors

And actively monitor temps. When it hangs, the last recorded temps should stay frozen on the screen and you can make a note of them.

dmesg -w

after reboot

watch -n 2 sensors output:
Every 2.0s: sensors

Adapter: ACPI interface

Package id 0: +63.0°C (high = 105.0 °C, crit = +105.0°C)

Adapter:ACPI interface
temp1: +63.0°C (crit = +95.0°C)

As soon as I type dmesg -w, it hangs

63 degrees is a bit high. That is 145 degrees F. Mine runs at about 30 degrees C average.
While it is not reaching critical temps, it still is running a bit hot.
I am not saying this is the cause, but it is worth looking into.

Do you still have the USB Installation stick from when you installed Zorin?
You might try booting the LiveUSB and testing to see if it hangs.

A good idea is to buy a can with air to blow your laptop clean from dust.
