Hello.
I have built a Linux workstation recently, with an AMD Ryzen 3700X processor and an Asus Prime X570-P mainboard (plus a Geforce RTX graphics card, m.2 SSD, 64 GB of RAM).
The system worked well with OpenSUSE 15.1 for about three months, apart from some instances when it slowed down considerably due to kernel activity apparently related to the graphics card.
Last week it suddenly rebooted, reached the login screen for a few seconds, and rebooted again repeatedly until I turned off the power.
I tried booting Windows, but the boot process stopped without even reaching the desktop.
I replaced the graphics card, but the problem remained.
I tried booting to runlevel 1, but this also gave me just a few seconds in a root shell before the system rebooted again.
I ran memtest86, and it worked without any problems and reported no memory errors.
Finally I replaced the mainboard with an Asus Prime X570-PRO, but this just gives me a few more seconds before the system reboots itself again.
Is there a way to find out what is happening, despite the fact that I cannot boot an operating system to, e.g., run diagnostics or even read log files?
Is there a way to boot just a minimal Linux system from a flash drive to let me access the log files?
What could be the reason for the system suddenly rebooting under Linux, failing to boot at all under Windows, and working without problems with memtest86?
Any suggestions?
Best regards,
Steffen
