Ran openSUSE Tumbleweed KDE 64Bit on a desktop for over a year.
About a week ago, the KDE desktop “KWin” would crash every hour.
I took the SSD drive out of the bad desktop and put it into a known working desktop with similar hardware.
I’ll run that for a few days to see if it still crashes which would eliminate hardware failure.
I would like to repair the broken desktop if it is hardware related.
What can I use to test all hardware on the desktop to see what needs to be replaced?
True hardware testing will be too lengthy and too expensive.You may run memtest86. Every component may fail, even the switches on the front panel. Connectors may oxidize. One of my machines reported all hard disks were missing. The DVD recorder had went bad. Removing it brought back the disks. A few years ago I even bought a used main board (11 € + 4 € shipping) which brought a machine back to useful life.
Moving components to a working machine and testing them there is a practical strategy. Disassembling your hardware and reassembling it step by step may succeed in identifying the defective component.
I ran all diagnostics, everything passed.
I then cleaned the computer and resat the graphics card.
Computer has been running over 21 hours with no crashes.
This is my most favorite computer so am hoping it does not crash anymore…
