PC crashes with no bluescreen.

[Tonayen]

Hey all. Been having some relative recent issues with my PC that i'm hoping you guys could try help me resolve.

 

The PC is from summer 2018

Specs;

8700K, overclocked 4.7-5Ghz through the motherboard option

Asus rog strix Z370-f

Corsair Dominator DDR4 3200

970 1TB M.2 ( windows located on this one)

860 1TB SSD

1060 3GB GPU

HX750i PSU

 

 

Things have been working perfectly well up untill August 24th. I moved my PC over to a new case and delidded my CPU with conductonaut in the process. Ever since, I have had random crashes,  1-3 times per day. The PC instantly turns off and reboots itself with no error or bluescreen. I havent been able to recreate the crashes on will, running stresstests with Prime95 or gaming, however I do feel it happens more frequently when streaming my desktop through Chrome>chromecast to my TV at bedtime.

 

I havent decided to venture back in my case mainly because I can't replicate the crash and therefor have nowhere to start looking really. Also been busy playing WoW classic so havent had the time, especially since DCing won't put me back into queue.

 

Any ideas what could cause this?

It might be the PSU going bad. Do you have a spare one lying around perhaps to swap with for a bit? I feel like it should be more reproducible with stress tests in that case though.

Unfortunately I do not have a spare PSU to test with. But I came to the same conclusion that if it was the PSU, I should be able to reproduce it more.
