Hello dear folks. Never asked before, never had to as well, until now.

Recently I got inspired by DDR4 and went all in, meaning I run:


  • ASUS X-99 Deluxe
    i7-5930k
    2x Crucial 2133MHz 16GB
    ATI HD 5850 or NVidia 780 Ti OC
    80 Plus Platinum 1kW Powersupply
    a Watt Counter
    Water cooling everywhere

Now, the problem is, i get a sudden black screen crash when using fancy 3d engine, like Wasteland2 (depends), Unreal Engine4 Editor (gives me a crash within a minute every single time)

I've been struggling for a week,

  • changing PCI-E slots,
    switching one 780 with another 780
    using Nvidia 610 or ATI 5850
    reinstalling windows
    switching from win7 to win8.1
    Downloaded and installed every motherboard related driver from ASUS hpage (chipset incl.)
    Tried four last NVidia drivers (back to May 2014)
    disabling most features i could find in BIOS
    enabling them back again
    lightly messed with over/underclocking
    switched slots for RAM
    taken off CPU cooler
    taken out the CPU itself
    checked thermalpaste
    constantly monitoring wattage consumption and temps of Cpu and Gpu cores
    Unplugging USB controllers
    Tried running heavy 3d render stuff like Otoy's Octane (ate 600W instead of Unreal's 400W)
    Been monitoring for GPU strange activity using GPU-Z
    3d mark crashes under extreme settings, but not under normal ones
    Enabling/Disabling Nvidia Control Centre's 3d features has no effect
    Enabling/Disabling SLI has no effect
    AIDA64 Stress test passed (ran for a couple of mins, though)
    Furmark burn test crashed only once, other 5 tests went fine

So far, there are no windows log entries about a crash itself. Only "Windows shut down unexpectedly" after the next restart.
Everything seems to work, with ATI/Nvidia 610, which are weak nowadays, and two 780's weren't bought to gather dust and they want get back to work :)

Also, another workaround is switching off every CPU core, but one.

It looks like a CPU or GPU problem, yet CPU stress tests have been all right, and not top notch GPU tests came out also fine. Maybe it's some conflict between the two. There is that distinguishable noise some thing makes when graphic card works really hard... Reminds me on crickets.

Crash description:
I start bunch of 2d software, Unreal editor loads a 3d scene, sometimes entering high-quality more, 10-30 seconds passes, black screen, UEFI and ASUS welcome me, PC continues to boot.
There are no(!) BSODs at all, just like a power surge.

Also, it haven't been always that way, bad things started to happen around release of Wasteland2 and me buying 2560x1440 screen. Could color profiles and monitor configuration cause all that hell to break loose?

p.s. I've been hearing high pitch noises from CPU/GPU since the Athlon 3000 times, so I figure it's normal, yet it makes me feel uneasy with all those crashes.

Please help.

One thing you don't mention is the brand or model number of the PSU. This sounds very much like it could possibly be related to power so maybe a PSU issue. Specs?

Have you checked manually for a BIOS update? These X99 boards have had some issues and a few BIOS releases in a short time so I'd get on that as well.

It took a month :) But yeah, it's never obvious if a PSU is damaged

Just created a new topic and noticed - there was something new after I gave up hope a year ago :D

Now it's a brand new flaming 950 Pro SSD from samsung which is awesome!!! Copies 2Gb files without showing up a copying window. :)
