Hi everyone,

My computer running a Z170 Stinger won't post. I was trying to play Last Remnant, went to load a save file and the computer just shut itself off. Now it won't power on and won't post. I've tried leaving it unplugged for a while but all I get when I flip the switch on the back of the PSU is an indeterminate number of flashes (sometimes one, sometimes 2-3, sometimes it just keeps flashing) on my cases's power button, along with . I was not experiencing any issues with the computer prior to it shutting down during (before starting, really) the game.

I've disconnected everything except the motherboard and the OS hard drive from the PSU (disconnected now are the GPU and two extra hard drives.) I've just captured the photo below of the 24-pin ATX connector:

When the switch on the PSU is turned on, one of two things happen: 1) The CPU fan twitches, the red light flashes once, and the yellow/white lights are stable, or 2) The CPU fan turns on, the red and yellow lights flash, and the white light is stable.

Here's the build as it currently stands:

Z170 Stinger (111-SS-E172-KR)
Cooler Master Elite 110 Case
Intel Core i5-6600k
EVGA 600 B1, 80+ BRONZE 600W Power Supply 100-B1-0600-KR
Crucial Ballistix Sport 16GB Kit (8GBx2) 2400 MT/s UDIMM DDR4-2400 (BLS2K8G4D240FSA)
Noctua NH-L9x65 Low-Profile LGA2011 with Fan 2500 RPM Bearing SS02 CPU Cooler
Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)
Sapphire Radeon R9 Nano 4GB HBM HDMI/TRIPLE DP PCI-Express Graphics Card 21249-00-40G (disconnected)

Other than a couple of (disconnected) 6TB HDDs I think that's everything.

Can anyone help identify which component has failed so I know who to yell at for warranty replacement and which to swap out with older parts temporarily?
