Turned computer on this morning and after a few reboots, I saw this in the logs:
kernel: [ 0.032415] mce: CPU supports 7 MCE banks
kernel: [ 0.044000] mce: [Hardware Error]: Machine check events logged
kernel: [ 0.044000] mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: fe00000000070f0f

Most of the advice says install mcelog, but this isn't available in the repositories any more.

mcelog was removed in Debian 10+ (Buster) and Ubuntu 18.04+
The functionality has been replaced by rasdaemon. Unfortunately the version of rasdaemon in Ubuntu 18.04 is old and is currently missing some functionality (eg: AMD CPU).
