Hello guys, I've been having an issue with my custom PC turning off at irregular intervals.

My build was completed 6/15/2015 and I've used compressed air on a monthly basis to clean out dust.

Specs:
CPU - Intel i5 4590 @ 3.30GHz with a Hyper 212 Evo cooler
Motherboard - MSI Z97 Gaming 5
GPU - AMD Radeon Sapphire R9 290
RAM - G. Skill Ripjaw 2x 8GB
PSU - Thermaltake Toughpower 750w Gold 80 Plus
Storage - 240GB Samsung 850 EVO SSD
Case: Phanteks Enthoo Pro Link to case
OS: Windows 10 Pro 64-bit
Fans: 2x 140mm top exhaust, 1x 200mm intake, 1x 120mm exhaust

Issue:
PC will turn off without warning, without BSOD, and without a Minidump (Minidump is enabled.)
During the loading screen of a CSGO match my PC will intermittently shut down and restart after roughly 30% of the loading bar. The same happens with Fallout 4 during a new save, my PC will shut down and restart during the loading screen.

I've also had the issue while simply streaming YouTube or Netflix with Google Chrome; however this hasn't been an issue after I switched to my Hyper 212 Evo cooler from the stock intel cooler.
PC Temps before Hyper 212 /// PC Temps AFTER Hyper 212 /// Unusual Mobo Temp

Resolutions so far:
I've RMA'd my PSU.
Reseated and rewired all connections and used compressed air on connectors.
Used each RAM stick individually on each of the four slots. (8 variations)
Upgraded my CPU cooler.
Removed my optical drive and HDD as well as their SATA cables.
Used different HDMI cables.
Changed from my surge protector/battery plug in to the outlet at the wall.
Tried using only one of my two monitors.
Reinstalled Windows 10.
Reinstalled the effected games.
Played CSGO using only integrated intel GFX to play (Successfully)

Now at first I thought, okay I need to RMA my GPU.
Yet I was watching Netflix while my GPU was disconnected while waiting to ship it out for the RMA when the PC turned itself off.

This made me uneasy that I had found the issue, although this hasn't happened in the last two days since I've changed my CPU cooler and dropped 50 degrees fahrenheit at full load.

I've ran MemTest 86 (RAM stress test) successfully, Prime95 (CPU stress test) sucessfully, as well as FurMark (GPU stress test) successfully.

Possible faulty RAM / Mobo / GPU?

Any suggestions would be highly appreciated. I haven't been able to play in four months.

I replaced the PSU with a EVGA 1000W (https://www.amazon.com/gp/product/B01LZ3SFB3/ref=od_aui_detailpages00?ie=UTF8&psc=1)
and have had no issues since.

My GPU has a suggested 750w requirement. (http://www.sapphiretech.com/productdetial.asp?pid=D4AC4856-9166-4C37-A7D6-ECDD3EEB4C17&lang=eng)

My best guess is the efficiency dropped for the PSU, or the addition of an optical drive or case fans created a starving GPU for power.

I haven't found a game that was uneffected.
I've tried FO4 and CSGO so far.

I'm running Radeon version 17.3.3

I find that really weird considering CSGO can be ran on a potato and FO4 takes some actual computing power to run.
Have you tried another GPU?

When did this problem start?
Did you make modifications to your build (add or remove anything?)

It's strange because CSGO/Fallout 4 will successfully load into a game at random.
Sometimes I'll be able to play a casual match, then join another and shut down.
Sometimes I'll be able to create my character on Fo4, walk over to Codsworth for some dialogue, over to the TV, and shut down. Other times it'll shut down at the loading screen.

The BIOS diag on my Mobo is usually displaying a number which does not follow a pattern.
37, 39, 40 etc... all showing that it's turning off at different initialization points of my Mobo.

I haven't tried another GPU, but I'll try that next.
Roughly four months ago.
I can't exactly recall, but I added an optical drive, and used an old SATA cable I found at work.
The optical drive has been disconnected for diagnosing.

The random numbers on your bios is the part that concerns me. Check your motherboard manual and see if you can find out what that means. If it's giving you random numbers each time it might be your board. But i'm not sure so check your mobo manual to see what those numbers mean.

This time it shut down while alternating between 41-42. I believe this is Early Memory Initialization.
Earlier it shut down at 39 which is Early North Bridge Initialization.

Here is the link in case I am mistaken.
Debug Code Table

I am about to leave for my friends house who has a known working GPU, i'll test and get back to you.

Edit: Stress test was successful, didn't crash on Fo4 or CSGO while using his GTX 970.

I ordered a GTX 1060 as a replacement, i'll update on Wednesday.

Edit 2: Turned my computer on this morning and it's turning off without a GPU installed...
I'll cancel my order.
New CPU or Mobo?

I wish I did.
I ordered a new i5-6600k, 8GB Ballistics DDR4, and a MSI Z270 Mobo.
Should fix the issue somewhere along the way. About time to upgrade to socket 1151, but I'm going to RMA all my old parts and build a second PC for my friend to buy off me.

Whatever works. Just don't go selling broken parts. Your friend would hate you.

Haha, I bet he would. I'll RMA them all beforehand. Thanks for all of your help, I appreciate it.

I got my new parts in today;
i5 6600k
Z270 MSI Gaming Pro
2x 4GB Ballistix Sport DDR4

I noticed my Mobo temps were quite different, especially on TMPIN5 compared to my old Z97.

I thought this might've been a faulty sensor, but maybe a heat related issue?

So are you up and running?
Also...Different software utilizes different temperature sensors that are placed in different locations on the mobo or the CPU.

You're not using the same motherboard or CPU, so you can't really compare those temps accurately. Power draw is different.

IE: If you are measuring CPU temp. Some (if not most programs) use mobo sensors that are near the cpu (not on it).
USE THE SAME SOFTWARE TO MEASURE AND BENCHMARK.
I see you did use CPUID, though.

Hardware is still different.

I hope your new hardware is working,
Harry

Hardware was working.... until today while playing Fallout 4, it turned itself off during gameplay twice....
Only thing that hasn't been changed is the case, SSD, and a refurbed PSU.
I'm going insane.

Is this issue only occurring during multi-player games? It may be a Ethernet driver.
I also hate to say it, but you may have picked up something nasty on the web. Do you use any malaware software or antivirus?

If you have a extra SSD/HDD around; I would recommend performing a clean install of your current OS and booting. Only installing a few of the games (for the sake of time) that gives you the issue and test out your PC with a clean drive installed.

Best of luck,
Harrison

I played Fallout 4 which is single player only, and still ran into the issue.
I use Malwarebytes and have scans on a twice a week schedule.
I reinstalled the OS on this SSD, but I'll reinstall on my second SSD after reformatting and creating a single partition.

I hope this is resolved by now, since I'm so delayed in responding to you. Any luck?
