Manjaro tends to use one of the core of my dual core CPU to 100% after some time of using the system

Hello everyone,
I am using manjaro xfce on a pretty old computer (Desktop) it is around 10 years old, after using the manjaro for around 1hour my cpu utilization reaches 100% and computer shutsdown.
I am using 64bit manjaro, RAM in my computer is 6 gb.
When I used htop to find out which task is hogging my cpu I got the command written below that was using around 100% of one core

/usr/lib/Xorg :0 -seat seat0 -auth /run/lightdm/root/:0 -noli

Please take the time to read the following post… :arrow_down:

Without the proper information, nobody is going to be able to help you. For instance…

  • Is this a desktop computer or a laptop/notebook?
  • Are you running the 32-bit community version of Manjaro, or the official 64-bit Manjaro?
  • How much RAM does that machine have?
  • Have you checked what is hogging the CPU core with htop or top, or perhaps a graphical system load monitor? (I don’t run XFCE, so I don’t know what it is called there, but in KDE Plasma it’s called System Monitor.)

@Aragorn I have updated my post according to the requirements can you please take a look.

if possible
reboot on USB iso manjaro

open 2 terminals
1 - check with top ( one cpu to 100% ? )

2 - returns inxi -Fxxxza --no-host
