help My pc shutts down :(

[Zusby]

Hello tech experts!
First thing first i want to aplogize for my bad english and probably bad explanation in this topic, english isn't my first language.

In the last year or so i've experienced many pc crashes that are happening everytime more often, at first i thought that my Enermax liqmax II's liquid reached his liquid usage and losing performance so I replaced with a €30-40 air cooler with about the same temperatures which arent too high and not much changed, I even replaced the thermal compound on CPU and GPU, still, nothing changed.
later on i noticed that my SSD isn't able to reboot anymore, the pc simply doesnt recognize the ssd when it reboots it's like if it is not plugged in at all if i'm rebooting the pc and i tryied to install windows on my HDD and see if the shutting down problem still kept happening, which did. ( At this point i was without hope, I was trying everything)

My temps are not the best in the world but aren't high enough to make the pc go in safe mod and shut down, i'll drag a screenshot of system critical shuts down log

The crash happens when i put the pc to a high stress or just leaving it on for a long period of time (12-14 hours), it just turns off as if i'd unplug it from the wall and plug it back in and restarts normally.

I've been thinking in the last days about the PSU, it could have gotten bad or even the motherboard if you think so what could i do to test if they work properly?

I need help :c
Thank you.

Is this straight crash-reboot or BSOD? If its crash-reboot, then PSU is most likely culprit. CM is bit hit and miss with PSUs, and there's always chance that even good quality unit just dies. If you can, try with another PSU. Do something which would normally result as crash. Another thing would be RAM (Memtest to check that out).

 

About SSD, you mean that Windows doesn't see it or BIOS doesn't see it? Again, if you can, try in another PC or by using SATA-USB adapter to check that it still works. If this is PSU issue, it may have died. You can also try swapping it to another SATA port and SATA power cable.

I did the memtest and everything is fine about the rams, I did try the ssd on another brand new pc and it has the same problem and i dont really care about it.

It is a crash-reboot, i've been fearing the PSU to be dying even because it's slowing getting worse week per week and at the moment i dont have €70 to buy a new one and even if i had them there wouldn't be a sure method to test the psu, (Yes, i dont have another psu to test)

Thanks a lot for the advices! really appreciated
