I have been using a company computer running Ubuntu 22.04. There are frequent and unexplained problems, like segmentation faults, stack errors, files disappearing, computer freezing or not booting, or turning off immediately after I turn it on. I don’t know what to do. The IT staff came to my office to check the computer and said “it was all good.” I am not allowed to boot from a USB stick or enter BIOS or open the case. I ran a command line memory check several times with no errors. There is an NVIDIA card, but it’s running X.org and usually headless. I mostly set up tasks via SSH.
What would you do?
You could download stressapptest and run that memory benchmark in the normal system.
I’m not sure how well the current version of Memtest does, but when I was overclocking I was told not to use it as it couldn’t reliably get memory to crash. (Funny problem to have). The two recommended tools are Windows only, so I found stressapptest as the best alternative.
I did run a similar test and there were no errors detected. Thanks anyway!
