Bounty: 100

I recently installed ubuntu desktop 20.04 on my machine which is otherwise running Windows 10 without a problem.

On Ubuntu it would randomly hang after minutes / hours. My first instinct was a memory issue, I currently have 48GB of memory installed (2x8GB and 1x32GB), what I noticed was that even the memtest would hang at 11% memtest

I then removed all combinations of memory sticks, but the only difference was that it would hang at a different test percentage. I also installed ubuntu server 20.04 but it seems to have the same issue.

I also installed new NVIDIA drivers, as I heard that this can be an issue, even though it seems weird that this would influence the memtest. No change.

How would I debug this ?

I found something about a crash in /var/log/syslog but I am not sure if this means anything.
