System: i7-2600k Intel CPU w. 212 coolermaster
p8p67 Deluxe Asus Motherboard
Corsair 750 hx PSU
G.Skill G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
EVGA GTX 1080 SC
Samsung EVO 850 256 gb SSD + an offbrand 1TB SSD for storage
1080p large format monitor on HDMI
Windows 10 64 pro
**Issue** 'black screen' sudden reboot when gaming, usually after 10-30 minutes after start. Sometimes much less. Confirmed in Overwatch, and in Ark survival evolved (ark seems much worse).
What I've investigated so far:
* I've checked Bios, Ram is clocked at 1600, CPU clock at stock (3.3-3.8boost) . CPU has never run OC'ed except for one testing session, where it ran stable at 1.3v @4.4 ghz with low temps. Owner doesn't need it OC'ed (family member) so he didn't want to shorten life of CPU possibly.
* I've repeatedly run Unengine Heaven on loop at 1980x1020 with max AA and medium tess. GPU temps stay below 70c at all times, card is not clocked higher than factory stock. Custom fan curve IS set through precision x for cooling. No reboots when looping Heaven, even for hours. No artifacts, no slowdowns. 3dmark firestrike and timespy also have been run 10+ times each, no artifacts or crashing.
* I've run a blend test in Prime95 and small FFT for nearly an hour each: CPU temps on blend never exceed 60 degrees C on any core, small fft test temps never break 65 degrees C. No crashes.
* Furmark and OCCT testing also produces no high temps and no crashes on either the GPU or CPU tests. PSU test passed clean.
* I've removed the PSU and tested the rails with a multimeter. Results: 12v rail-12.22v all, 5v rail - 5.04 v , 3v rail - 3.35v, -12v rail - -12.09v. These are all well within tolerances.
* **I've fully wiped and reinstalled Windows 10 from scratch**. All drivers and updates brought up to date, including Nvidia drivers. GeForce experience is NOT installed.
* I've updated the BIOS on the motherboard.
* I've run MEMTEST from a USB stick, no issues.
----------------------------
I'm at my wits end. I've just pulled the power supply, and stuck in an old Raidmax 630ss to see if there's any difference with that, he's currently trying to reproduce the crash with that installed to try and rule out PSU problems.
I've looked up the exact issues from the event viewer in windows, but It doesn't give me much: 0x8000400000000002 . A kernel event id 41 only means an unexpected power problem has occurred and is what happens with both an unexpected shutdown/restart.
I've poured over every forum I can think of, but I'm not getting anywhere there either.
**What the hell is going on!!!!!!!!!** Any ideas or help appreciated, because the only things I can think of to do now is swapping Motherboard, CPU, RAM, which I have some RAM to swap out, but I dont have a CPU I can throw in there, nor a spare MOBO. So I would have to buy those, and that's silly for an undiagnosed problem.
