So my z390 dark came in on friday and I finally got the chance to install everything in my Evolv X. After a few hours of routing cables neatly and such the system booted up first try. All bios settings were left stock, and the system booted into windows without any issue. It was dinner time so I decided to stream some music on the pc while I went to cook. Halfway through making dinner I hear the music cut out and turn to see the PC shut off.
 
I open up the case panel and check to see if anything fishy was going on inside in terms of cables, but nothing was misplaced/out of the ordinary. I switched the psu off for a minute and then back on. I then attempted to power the pc up with the onboard power switch, i hear my switch on but the pc does not start up. A few seconds later the leds on my ram come on, and thats when i notice the voltage status shows no source for vcore, vdimm, and the other major cpu voltages.
 
Everything was connected properly, nothing was overclocked, nothing in the bios was modded except for disabling fast boot, and the entire pc power wise is on a surge protector. I'll swap the cpu back over to my Aorus Master but I'm fairly confident it's dead. System was running fine since November, and I just had to go and buy the Dark :(. I'll do some more investigating and update the thread as I go, but the only change in system config was the z390 Dark.
 
Specs:
 
8700k
EVGA z390 Dark
2x8GB Trident Z 3600
EVGA G2 750w
Evolv X
970 Evo m.2 (main SSD) 

What were you running for cooling, and what is the GPU?

Thermalright TS140 Direct with MX-4 for cooling
Radeon 7 for a GPU
 
Everything was installed properly, and clearly the system worked (however short lived that was), OS install is likely 99% irrelevant, made sure not to over-tighten any part of the mounting system for the cpu cooler as I always do.
 
Cooked wasn't the proper term, or at least not yet, I'll take a look at the back of the PCB and also check the CPU when I remove it from the socket to swap it to the Aorus Master.
 
And yes I bought an EVGA Dark to not even bother mounting a CPU cooler to it and expecting my cpu to survive...
 
The only indication as of now that it was the board was the fact that I've had the same exact system running without issue for 5 months now. The only change to the system was the Z390 Dark, and about 10 minutes after booting and getting into windows it randomly dies out of nowhere.

Swapped to another memory kit, and trying single sticks/different channels to no avail.
 
Currently I get no power to the status LED for Vcore, Vdimm, VCCIO or VCCPL with the system powered "on" (doesn't boot, post, or show any boot sequence codes, only gives power to dimm LEDs).
 
 

How old was that PSU?

Are you going to be using the same PSU?

PSU is 3 years old I think, was RMA'd for a replacement unit at some point because the fan died.
 
No scorch marks on the PCB or CPU as far as I can see. Calling it a night for now, I'll drop the cpu into my CM5 and Aorus Master setup tomorrow.

Let us know if that CPU is working in another system!

"different pair of PSU cables"?
What Two Power Supplies?

What is a CM5 Maker?

Did you Bench Test the EVGA Motherboard?
That is test the MB not mounted in a Case.

Just to clarify, you did not mix / use the cables for the EVGA PSU with the C5 correct?

Edit:  The answer to the question I was going to ask has already been answered.

Oddly I had this exact thing happen recently on a z370 ftw. Was watching YouTube and it just shut off on its own. My testing found the cpu to be dead (g5500 was able to boot) so I bought an aorus master and 9900k.

I don't trust evga mother boards any more, especially after seeing your similar situation. CPUs statistically don't just randomly die.

On another note I'm really happy with the z390 aorus master/9900k.

In post 14 OP edited his post and said "He put the CPU in another board

Sorry you had issue with your board and CPU. Bad boards are not common, but do happen.
The OP edited his post in post 14 and said " He swapped out the CPU into another board and the CPU was fine"
He is going to RMA the motherboard. It happens with electronics, I bet about 5% go bad.
Always seems 10% of reviews on most all/any computer parts, 10% of the reviews are bad.
 
I have two EVGA z370 FTW boards, two x99 Classified and one x99 FTW, one x79 classified, one Asrock 370 killer, one Asus x99 Strix, five Asus x79 P9 IMPI workstation boards, two Asrock dual socket LGA 2011 They all work fine, no issues at all
One other EVGA x79 I have has issues, but it looks like it has a bent pin or two. Going to try to fix them and see.

Yes. Tested every possible configuration I can without having access to another CPU or PSU on hand. Every piece of hardware works perfectly in my other setup. The Dark will not post; powers ram leds, but voltage indicators show no vcore, vdimm, vccio, or vccpl present (according to onboard indicator leds). I can hear the PSU switch on, but aside from that and the ram leds nothing happens.
 
Ive tried no gpu, 1 dimm (both slots), different set of ram, no fan headers connected, different psu cables, no ssd, both m.2 slots. All result in the same lack of post while all of the hardware works with my Aorus Master.

Did you get any POST code outputs or anything?

That is about what my Z370 FTW MB did with my 1300 G2 PSU, I used a SuperNOVA 1000 G3 and it fired right up.
