PC Shutting down by itself

Wootperson · January 31, 2019

So once i finished my new PC build i started downloading stuff first i played Sea of Thives for about 3 hours and everything was fine

Then i played some CSGO and 30 minutes into game pc just shut down it didnt go thru shutting down faze it just turned itself off

so after my 30min ban was up in competitive i went back in and tried again same thing happened around 25min in this time

Today i tried running CPU and GPU stress together just to see if system would hold and PC shut itself down exactly same way

after shutdown it boots back up normally tho

Can this be a issue because of overheating? or some other bigger problem i dont know

I have new cooler coming in tomorrow and new bigger case for better airflow also different thermal paste

i am thinking it might be from overheating but i dont know really

My case is H340 from Nzxt back Fan space is used for H80i fan/radiator top fan is missing i couldnt install it because of H80i tubes and i have two Fans in front

i thinks its because of air flow when PC was making noise and trying to keep up with heat i checked and there was Hot air like from hair dryer coming from top small holes (where missing fan should be)

Also my motherboard has 8pin plus 4pin for CPU power i have only 8 pin plugged in can that be a issue?

Move the radiator to the upper front slot(push intake) and move one of your intake fans to act as exhaust at the back where the radiator used to be. You will get lower temps for cpu.

What psu are you using? Can you try to plug that 8+4?

It should be enough and that psu has 2x 8pin(4+4) EPS (CPU). So try plugging both of those in.

Moving the radiator will drop temperatures quite a lot. You will no longer cool the cpu with air heated by your gpu and you will exhaust a lot more air as there is no resistance from the radiator. I would also enable xmp for memory if you are not running those sticks 2133MHz on purpose.
