Computer keeps shuting down and restarting

[Semi_di_Girasole]

Hi all,

I noticed this issue a week ago but was very random, happend 1 or 2. I needed to update the nvidia drivers and this moring the new windows update also came. 

Today I had 7 crashes already. The computer will just shut down with no error message what so ever and then restart.. Once I saw a C:drive repair but that's all.

It's not the temperature of the cpu (always between 30-50), the view riability shows just a crush of remsh this morning and then only "windows was not properly shot down"

I updated the drivers for nvdia. I restared, did a virus scan. I used the computer normally only few pages of windows and i worked for a while, then I opened overwatch and BOOM crash again.

Is the gpu failing? 

I bought all the parts 6 mouths ago so they all have warrenty. It's a new desktop, specs are :

Mobo B350 asus prime-plus

Ram 2 8gb sticks corsair vengeance 2900

power supply 650w corsair 

CPU ryzen 7 1700 with the stock cooling

GPU gtx 1080

ssd : samsung 500 gb 850evo

hhd : toshiba 2 terabyte 

 

I still can't figure out if it's a software or hardware issue but at this point it might be a hardware going to failure type of situation. Please help.

does it say "windows is shutting down" ? or does it die like the power went out, and then it comes back on or something?

if it dies like the power went out, its most likely hardware, ram is a good place to start if this is the case

Yep just like that no error message. 

I did a ram test and nothing was found. Since the computer didn't start correctly I did a windows repair and just when I was installing stuff is it did it again...

So it's not ram and not the ssd. Might be the power supply or the gpu? How can I test that?

I'm going to say this up front, most hardware testing is useless a lot of the time, it's not always useless, but you will be surprised how often it will say something is working, when it is clearly broken. 

 

More than once, I've run a 24 hour ram test trying to figure out a hardware issue with no problems listed from the test, yet the problem persisted, I replaced the stick of ram that I believed was bad, despite the tests saying it was good, and problem solved.. 

 

Think of it like this, you are asking a broken piece of hardware, to tell you if it's broken.. If the hardware is broken already, how does it know that something is wrong? And how reliable do you think it's answer is going to be if the thing is damaged? 

 

I'm only saying this because I want you to understand that those tests are not very reliable. 

Unless it's a PowerEdge or something with parts dedicated to testing other parts( and not parts doing a sort of self diagnostic), the results won't always be that reliable and can trick you. 

 

With that being said, how are the Temps looking, are they in the higher range like 70-90C, and are all the fans working?

You can check this in bios

 

Do you have another PSU you can replace yours with to see if the problem goes away? 

 

And I still recommend pulling all but one stick of ram and testing it out.

If it occurs again, try a different stick and/or another slot. 

 

Off the top of my head, this sounds like PSU, ram, or maybe motherboard, but hardware diagnostic is always a hit and miss science, your going to have to try everything. (sounds alot like ram though, but try everything) 

 

If nothing above works, you are going to need to pull all the parts out with the exception of the cpu's, ram, gpu(leave it in only if you don't have integrated)  and power to the motherboard

 

Make sure you disconnect all USB devices and power to anything you don't need like CD drives.

 

In this scenario you will need to connect the hard drive to let it boot to windows, seeing as it gets this far on its own usually (at least that's what it sounds like) 

 

You want to try and trigger the by failure doing this. 

If you can't get it to fail, then probably one of the removed parts is broken, and you need to add one back in at a time, testing each time to see if it fails on a specific part.

I sweaped the ram and it will not boot at all now. I don't know what else to do at this point if not calling a service to repair it.

sounds like you are going to need to do this now,

strip it down to bare minimum needed to post

remove all but one stick of ram

remove the gpu, use the integrated video

disconnect power and data to the harddrives and cd drives

remove any usb devices except just the keyboard

 

you just want one stick of ram, the cpu, power to the motherboard and cpu power port

see if the screen comes on and it passes POST

 

Also, do you have a spare psu you can use? maybe from another computer?
