How would you troubleshoot if your computer had sudden instant shut downs?

I am probably not alone in saying that we have all experienced sudden shutdowns in our computers. Moreover, I am curious how you troubleshoot your sudden shut downs.

What precautions do you take to avoid it from happening again in the future? Make any changes in BIOS when your computer gets old (total runtime of 3 years+)?

First thing check temps.

Next, test at least 4 alternate kernels.

Mostly if youre running a stable system youre computer would not instant shutdown suddenly.

Got this sometimes if i overclocked to heavily and have done prime benchmarks 6hrs +.

If the computer still starts:
Reset BIOS Settings to default and disable secure boot.
Also you can enable the XMP Profile if you got one.

If computer not starts:

Check every cable in your pc, reset your cmos, ..

And check your Temps, since it most systems will freeze if overheat.

Overheating, sudden electricity jumps, BIOS/UEFI bug, faulty hardware (like broken HDD/SSD/CPU/GPU etc.) and then there are the journals in your OS.
