Computer randomly shuts down

[WalkingBread]

so i have a amd A8 based system, with a MSI Greade motherboard. the issue im having with it is it randomly shuts itself off. ive checked temps to see if it was a CPU overheat issue. the idle temp is 16C so that cant be the problem. my first instinct it to say its the motherboard or power supply. any ideas on what i should begin testing?

that can't be right

power supply.

PSU is most likely the issue

PSU 

motherboard

 

that two are your suspect... 

but i would go with psu cause it is the common culprit in that situation...

this is exactly what i was figuring, luckily i came across a gold 750W i can use, thank you guys for confirming my thoughts.

how can idle temp of 16C not be right btw? its a CLC system, both open hardware monitor and cpu temp show the exact same temp

so the PSU is the culprit here? 

is your problem now solved?

im going to be swapping out the PSU in a little bit and i will update with results. interesting thing to add though, when i went to work last night i made sure to shut the pc down buit forgot to flip the power switch on the PSU. when i got hom the pc was on. could the PSU short and cause the system to turn on?

ok so the pc has been running for a while with the new psu in there for a while now, im running prime 95 to try and stress the system. its really slow, i noticed the hdd is running 100%. looks like it may be time to reformatte

spoke too soon, system just shut down

[rheyL]

you might want to sort it more faster

take all parts out of the case and try booting it without the case if you suspect short-circuit. 

 

as to my experience, motherboard standoffs cause short-circuit, to that point i put masking tape on it.

so it wasnt a short circuit or the mother board, for some reason im getting different temp readings accross 3 different programs. the CAm software that works with the pump for the CPU cooler reads 45-60C while idle, the cpu temp and open hardware monitor reads 20-30C. the bios reads about 30 at startup. i think the cpu is "overheating" and triggering a shut down.
