[solved] unwanted power off, requires hard restart, good PSU & MB & HDD [PSU]
my k8 desktop system has recently started to power off after less than a minute of power on.
I have checked and cleaned the MB & fans.
I run memtest+ RAM weekly & it is good.
I always enable smartdrive and SSD remains good
I have booted from USB sticks and system will power off in less than a minute.
I have reset the BIOS and tested optimized & failsafe modes, power off still happens.
BIOS reports PSU is good, no fluctuations or over voltage.
I removed SSD, video card, optical drive. still have problems.
MB is Gigabyte GA78LMT, an ultra-stable MB they claim
what else ?
kernel is always kept up to date, 4.15.0-45
is it possible kernel or worm infected BIOS even after reset?

Hi galen,
Sounds more to me like a CPU temperature issue than a software infection of some kind. You've already done some good hardware and BIOS troubleshooting - have you looked into the temperature thing ? Even though your fans check out OK, maybe it's a heatsink-thermal paste-CPU based problem.
There are utilities out there (memory fails me as to their names ... *sigh*) to look into this. If you choose to do so and can't find them, feel free to return for more help.
Oops I forgot to mention BIOS diags reports CPU temp 42-51c.
I also checked for shorts, screwdrivers, screws, wires etc.. nothing.
checked for AC on PSU outputs, none found
