Hi there.

First my pc specs:

i7-4790k H100i
MSI z97 gaming 5
AMD r9 280x crossfire
16gb ADATA 2400mhz (running at 1600mhz 1.5v)
Corsair ax850 PSU
2x SSD 2x HDD
Sound Blaster z

So my pc is just switching off at random times with no errors regardless of load on the system. It's like some protection is taking effect. it's doing this like every 1-3 weeks+ but very strange. How would I go about testing it.

I did test with aida64 by stressing the memory, gpu, fpu, cpu, etc at the same time and checked voltages with hwinfo and everything looks just fine. So can anyone tell me how I would test this further? This looks like either a motherboard issue or psu issue. This all started a month ago. So far I only experiencing this issue when idle. I can play bf4, black ops 2, GTA 5, project cars, etc and no power issues.

Hope any of you can help me. Just tell me if you need more info please
 
First thing I'd do is swap PCU with one that you know works 100% with no issues.

Run your system for about a month on that and see if problem persists.

THEN start fiddling with settings and other hardware.

I don't have one and to get a decent one is expensive
 
Have you overclocked your setup ?
Have you tried stripping the PC to the barebones eg. one ram dimm no GPU, sound card and one drive?
My bet would be on the MOBO or PSU.

I was also thinking either mobo, psu. Now I can strip it down to 1 stick of ram and no gpu but here comes the BIG issue. I don't get this all the time but at random times. So not sure how I can go with just 1 stick of ram and no gpu for a very long time. I did overclock my cpu.

I have it on 4.6ghz @ 1.26V and memory is set to xmp profile. What is the chance that memory or the cpu memory controller could be unstable when set to xmp profiles. I also checked my power settings and by running cmd as administrator then run powercfg -h off to make sure it's not that but how can it be that. The problem is that when I get the issue it's like someone unplugged the pc from the wall.

The is one funny issue as I don't know how I will test this cause it's happening at random times. Maybe I should wait for the problem to get bigger before I do something. The bigger the problem the easier it is to solve it.

Oh ffs just shut the fsck up, you have no proof that it's the MB. It might be the MB but it also might be related to any of the other components.

The only way to solve this problem is through a process of elimination, it could be the MB, it could be the PSU or it could be something else.
 
I prefer MSI to really expensive ASUS's (I own multiple mobos and MSI just tend to be better and less gimmicky to really expensive ASUS's....)
 
OP,

you said you overclocked the CPU.
Try maybe set to OC halfway between what you changed, and where it was originally.

And after that (contrary to the popular belief...) Try change your GPU or run onboard, taking out the gpu. (yes, you might have to give up a game or two, or have low graphic settings.

You could also clean the RAM chip contacts with a soft white eraser.

Should I have mentioned it was my opinion?

Thanks for the info FFS you always come to derail a thread. You speak like the typical Asus fanboy. If you don't have anything to contribute then rather not say anything. What if I change my motherboard to ASUS and still have the same issues. Can I come to your house and give you a PK in the face...lol?

You did it in the past with one of my threads

Any proof that it's my motherboard?

Thanks for the info. Will try the memory thing. Wow having to play bf4 on low at 24fps so cinematic..lol. I guess onboard intel hd4600 won't be able to run my qnix qx2710 and thus games even on low

Is your m/b flashed with the latest bios version?

So your PC shuts down after awhile when you're not using it? Have you checked the Win Event Viewer?

My PC did that - wasn't a hardware problem. It was Win shutting down the computer, as if Win was powering down due to a Power Options setting or at times after installing an update. I reinstalled Win and the problem went away.

But there could be any number of reasons why your PC is shutting down - cannot exclude hardware.

The same symptom as pulling out the plug. In event viewer it states that my pc recovered from a unexpected shutdown. I also logged aticket with MSI support and they said I must try disabling c1e. I also have spread spectrum enabled and when overclocking it must be disabled.

Like I said I have my cpu at 4.6GHz at 1.26V. i added voltage just to be on the safe side for now. So I will try what MSI suggested
