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

[shiv1]

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…

How to provide good information

Welcome to Manjaro! To allow all of us helpful gurus on this forum TO HELP YOU, we need some basic information about your system. This probably means you described the symptoms of your problem, but now we need some more information to know where the origin of your issue is exactly. Someone probably linked you to this tutorial, so if you’re reading this in response to a question, please click the green link above this text to bring you to the full and unabridged text of the tutorial…

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

Hi, I’ve been with manjaro for 5 days, approximately, I like the distribution and its ease, I am one of the people who likes to save resources to use them in a certain place to the maximum benefit and I realize that manjaro always needs to use 100% of the CPU of two cores, I don’t know why that happens or is it necessary to always consume 100% of two cores.

Open up htop and look for what process is eating your CPU time.

Hello again, thank you very much for the welcome :), because if that I always see with the naked eye and kill programs that I know, but some processes I don’t know how to identify them and I better not touch them, I already spent several times to end processes I had problems in the future, I prefer to leave it to software I recommend, and that is what I did; download auto-cpufreq and install it, then restart it and now everything normal I gave it the same use as before but this time the processors are not going crazy going up to 100%.
