i7-10510U was launched nearly 4 years ago, so is clearly old enough for mature

This failure description suggests to me to do what follows expediently with
expectation it needs to be returned for exchange or refund due to hardware defect:

1-check if a BIOS update is available
2-make sure applicable firmware is installed
3-If it has only one RAM stick installed, try it in a different slot, and install
a matching second. If 2 or more, swap them around.
4-run memtest at least 4 full passes. 1 only is inconclusive.
5-check whether grub linu line addition
	nomce
had any effect.
6-Check with live media of some other distro, e.g. TW.
