PC crashes while playing

[teemuhax]

Hey guys,

I've been having issues with my PC randomly crashing while playing WoW. The crash is similar to just pulling the plug on my computer, it just instantly shuts down.
I feel like this started happening as I installed MSI Afterburner and overclocked my GPU a bit, at first it ran fine for weeks, while all of a sudden I started getting random shut downs.
I figured maybe something was wrong with my overclock so I decided to stress test it more, however nothing happened even though I had it running the whole night.
When I check event viewer it seems to always be the same Event ID 41 Kernel-Power System, google has a ton of random issues causing this and even more ways to fix it, having tried some and still not being able to fix it I come to you.
I feel like I don't get crashes as often if I don't have an overclock on, but today when I tried it without any overclock (aside from a custom fan curve), it crashed a few times during gaming.
Does anybody have any ideas what might actually be causing this? 

 

Also, I've tried to keep an eye on my temperatures while playing, and I don't really reach any high degrees, only on my GPU if I don't have the custom curve on.

Here are some of my specs:

PSU: Corsair 750W 

Mob: Gigabyte Z97P-D3
CPU: i7 4790k
GPU: KFA2 GTX 980
RAM: Corsair 16 GB

OS: Win 10

Does your system restart automatically?

Yes -> most likely a PSU problem

No -> most likely an overheating problem

It does restart itself automatically, is there anyway of monitoring what's going on in my PSU?
I just find it hard to believe that it would be the cause of the problem, since it's fairly new and has been working fine for over a year.

Only very few PSUs support a connection via USB, to directly monitor them.

You could still check the voltage readings from the mainboard with a program like HWiNFO. But voltages alone don't make a working PSU.

Heat can cause this kind of behaviour. Run prime95 and check your CPU temps.

I doubt it's my temps, while running prime95 my cores max at 58 C.
Motherboard max temps are:
TZ00 28 C
TZ01 30 C
TMPIN0 43 C
TMPIN2 49 C

Temps are fine. RAM is what i would test next. If a cluster is corrupt and your system try to use it, the system will crash. But normaly with a bluescreen. To be sure, let memtest run over night. I doubt your PSU is causing this.

 

If you do it, run several instances of memtest, each 512mb big. Run as many instances of it, till you reach your total RAM Amount.

Hey guys! 

I wanted to bring you an update on the issue. I actually managed to recreate the crash, by having furmark and prime95 heavy PSU load on, my computer crashes almost instantly. So it has become near obvious that the problem is my PSU, although I will try and measure it with an ammter just to see what exactly happens with it.

Wanted to say that problem indeed was my PSU, got a new one and everything is working fine.
