PC shutdowns randomly after SSD install (Samsung 850 Pro)(Solved)

hi all, very strange thing I've been experiencing lately, my computer shutdowns randomly.

Complete shutdown, not reboot, usually after a few hours of being on.

It started occurring just after I installed my Samsung SSD (850 PRO 512Gb) and a new install of windows 8.1..

At first I thought it could be overheating, so I opened the case, running temperature logs all the time.
I caught a few reboots happening on the logs and it's definitely not temperature related (cpu is around 31°C, GPU is at ~40°C, all other sensor are perfectly within range). Also it usually happens (90% of the time) when I'm not even in front of the PC and the it's not really doing anything.

I also thoroughly checked Windows' event viewer, but there's absolutely nothing in there indicating a problem, except when I finally start the computer after a crash I see a "The previous system shutdown at 6:13:14 PM on ‎2016-‎03-‎14 was unexpected." but that's about it.

A few other things I've done so far: swapped my GPU on a different rail of the PSU, tried with each of my DDR sticks individually, updated firmware of SSD.

At this point I'm kind of suspecting a PSU failure, but it's odd that it would start happening right after a fresh windows 8.1 install on a brand new SSD, no?

I'm at bit of a loss here, any possible feedback appreciated!

Here's my full config:
- MB: ASUS MAXIMUS VII HERO (Z97)
- CPU: Intel Core i7 4790K (with Cooler Master Nepton 240M)
- SSD1: Samsung 850 Pro 512GB
- SSD2: Samsung 840 Evo 250GB
- DDR: 8Gx2|GSKILL F3-2400C10D-16GTX R
- GPU: EVGA GTX 970
- PSU: Corsair HX1050

That motherboard has two different SATA controllers:

Intel® Z97 chipset :
6 x SATA 6Gb/s port(s), red
Support Raid 0, 1, 5, 10
Supports Intel® Smart Response Technology, Intel® Rapid Start Technology, Intel® Smart Connect Technology *3
1 x M.2 Socket 3, black, with M Key, type 2260/2280 storage devices support (PCIE mode)
ASMedia® PCIe SATA controller : *4
2 x SATA 6Gb/s port(s), red

With the following footnotes:

*3: The supported functions depends on the CPU installed.
*4: These SATA ports are for data hard drivers only. ATAPI devices are not supported.

Double-check the SATA ports with the manual and make sure you are using the Intel SATA ports. Make sure you've installed the correct chipset drivers as well.

If you used the latest Nvidia drivers during install, either 364.47 or 364.51. Both have numerous instability issues reported, and the .47 release was pulled by Nvidia over it. the 362 were the last really solid drivers, here is a link http://www.nvidia.com/download/driverResults.aspx/99202/en-us

Make certain to thoroughly remove the others first, if you are indeed using them. Do not simply do an express install.

That the system is shutting down and not rebooting points elsewhere. But as the logs show nothing detailed, try http://www.resplendence.com/whocrashed May be it will find the culprit.

If it is the psu; very odd. Your setup is nowhere near taxing it. Of course if you are overclocking that K model, and did not mention it. Obviously put everything back to stock until the stability issues have been resolved. And judging by your initial post, you knew better than to do a OS install while overclocked too. :)

Also not a bad idea to update to latest mainboard bios if stability issues occur after new hardware install. Provided you do not have the latest already.

And as an aside: I could see holding out on going win 10 if you were on 7, but 8.1? Your reasons are your own, I just see little point in avoiding 10 in that situation.

Could be a flaky PSU, which can cause all sorts of weird and hard to nail down problems. But the issue with possibly not using the Intel SATA ports makes a lot of sense.

The issue AnonymouseUser pointed out has been seen multiple times in the forums, so it should be the first place to check before guessing at other culprits.

Thanks for the feedback guys, here's what I did since last post:

- Changed the sata port (it wasn't on an ASMedia port though..), changed bios settings for that port to "not hotplug" (it was on before, never know..)
- updated intel chipset drivers
- before, all my components were powered by the "default" cables of the PSU that are not modular. I've now switched the GPU on a separate slot (hopefully a different rail?? no idea..) and the SSD has now it's dedicated psu slot as well.

So far, no crashes to report, which is a good sign, but sometimes it wouldn't happen for 2-3 days, so I'll just let the pc running and see..

If it turns out that didn't work, then I'll look into maybe installing "whocrashed".

Just for precision, my cpu is currently not overclocked (first thing I turned off when it started shutting down).

And for the windows 8.1 thing :).. honestly, I have windows 10 on my laptop and my HTPC and I like it less than 8.1.. hated windows 8 when it came out, but 8.1 and a couple things like classic shell make it quite usable.
Probably just a preference thing (I really don't like how windows 10 forces stuff down your throat (cortana, bing search associated with it, no way to easily turn updates off on the Home version, how you have to dig in the settings to get acceptable privacy settings, etc..) maybe that's just me though :D

Well... definitely not fixed, just had it happen twice (once last night, and once 5 minutes ago while I was just browsing).

Since it's a complete shutdown and not a reboot I'm more and more inclined to suspect a hardware failure of some sort (PSU? MB?) the weird thing is that in my BIOS I've setup the PC to boot itself after loss of power, so technically if it was PSU related, shouldn't it still restart after?

At a bit of a loss.. any other ideas welcome!

HI John., did you ever get this fixed ? I am experiencing the same issue after installing my Samsung 850 Pro last week. Thanks !

Going back to John's last post, if it's the power supply, and it shut off the computer due to overload, then no, it would not restart the computer immediately after without intervention.

caruser25, welcome to AT Forums. Please start a new thread so that we can assist with your individual issue, and not get it mixed up with any other input that John may have.

Why would he need to start a new thread? He's hoping to flag down John's experience specifically as the last post was March 21.

Right, I did not start a new post as I have exactly the same symptoms as John had. My environment is a desktop system, ASUS P8B75-M system board which has been working excellent with my old OCZ 128GB SSD for a few years. I upgraded this SSD to Samsung 850 Pro last week and since then I am experiencing these spontaneous power downs after about 20-30 minutes. Immediate restart is possible, not temperature problems, I am running W10 latest update, BIOS is also latest version (although from 2014 but no newer version is available).

Even with it being 2016, he's hoping to flag down John's experience specifically.

I think what escapes people that want to bark at folks to make a new post, is that OFTEN times a Google search is what brought them to a specific thread in the first place. If google turned up only a handful of items to look at, and you happen to be a member to one of the items that were brought up, you post hoping for the resolution that the OP of that thread came up with.

Well maybe after being gone for almost 13 months, John7452 will log back in and share if he found a way to fix it.

Caruser25: Asus last listed a SSD compatibility list in 2015, and the only Samsung SSD they list is one 850 EVO model. Try contacting their tech support via email to see if there is any known compatibility issues with the 850 PRO. It's not very common, but I have seen a few cases where a particular SSD would not work correctly with some motherboards. If they are unable to help, please create a current help thread for your situation, as I have a feeling the author of this post is not coming back any time soon.

A quick look around shows a number of reports of random shutdowns with your board. Some went on for quite a few months ending in a dead board. Having added the 850 pro may be simply a case of coincidence and not causation.

What a CF.
Both OPs have spontaneous power downs and in all this time, neither has checked the power supply?
I have land for sale.

Hi All,

Just posting the end result here:
After testing with Linux, Bios only and even putting my old disk back, the spontaneous power down remained in all situations so it was deemed a hardware error on the system board. After testing power supply, memory and processor which all reported fine, I replaced the system board and the issue is now solved.

Tks for your suggestions.
