PC a bit unstable

English Hardware
1

What happens.

I move my mouse, and I see the mouse pointer freezing. Then the only way forward is to hold the on off button for 5 seconds, and start over again.
If music is playing it keeps on playing, also if a vid is running it keeps running.

First question, Is there a way to see in logs what is going on ?

Second question , should I get different ram ?

Now why do I suspect the ram ?

This pc was never as stable as my previous PC’s on Linux, although on previous pc, I was running leap, not Tumbleweed.

When this pc was only days old, a dutch computer forum told me to increase the memory speed in the bios to the advertised speed of the memory.
( so my mobo does not recognize this memory at its advertised speed)
This how ever made my pc quite unstable. Leaving the memory speed at what the mobo came up with was already a big improvement.

The problem never went away 100% though, although it sometimes does not happen for days.

Looking at current ram prices does not make me happy though.

Mouse Logitech G203.
Ram: G skill

Any suggestions ? :slight_smile:

Do check your RAM if you believe it is involved. Use PCMemtest or similar applications for RAM test. Check if some applications or processes are spiking when your computer freezes. Use top or htop or similar programs for that. Look in your journal if you find some strange entries…

Many ways to investigate this…

Don’t forget to take a look for the right ram as specified in your pc’s specification.
A bit of a mistake will not give you a positive result.

I will try PCMemtest. :slight_smile:

But looking in journals? I can only do this after I restarted my pc.
The keyboard also does not respond anymore when this happens.

Could it be related to this ?

My PC:
openSUSE Tumbleweed 20221105
KDE Plasma-versie: 5.26.2
Versie van KDE-Frameworks: 5.99.0
Qt-versie: 5.15.7
Kernel-versie: 6.0.6-1-default (64-bits)
Grafisch platform: X11
CPU: 12 × AMD Ryzen 5 2600 Six-Core Processor
Geheugen: 15,5 GiB RAM
Grafische processor: AMD Radeon RX 570 Series

So I should not be affected by that bug, because I have a 2000 series cpu. The bug is about 3000 and 5000 series cpu.

Based on what you write, music/video keeps on running, something with the USB subsystem could explain what you see.

But looking in journals? I can only do this after I restarted my pc.

Yes, but that is not problem, right? If there are USB problems, it is very likely the journal will show them.

If you really suspect memory, you can also try second-hand, I did upgrade my machine to 32GB for a good price using memory bought on marktplaats.

Its a weird issue, it sometimes does not happen for days, but I am typing this for the second time, because it just happened again.
But that was the first time since my post here.

Think I will try different memory.

Maybe ask at tweakers for advice on what memory to get. (for the non dutch here tweakers is like Toms hardware)
