Hi!
I have a 14-month old build that has been working great up until yesterday. It has had fairly regular usage and there have been no problems. Here are the specs:
Motherboard: ASUS Z170-Deluxe
CPU: Intel Core i7 6700K
Cooler: Corsair H100i GTX
RAM: Kingston Savage Black 16GB (2x8GB) DDR4 PC4-19200C12 2400MHz
PSU: 760W Corsair AX760
GPU: Gigabyte GeForce GTX 980 G1 Gaming 4096MB GDDR5
Last night I was playing a game and my machine cut out and rebooted itself. It failed to POST, and has not POSTed ever since.
Steps I have taken to try and fix it
I have already...
From reading other threads about Z170 chipsets and q-codes such as 62 and 79, I think I have a hardware issue - but my question is: which piece?
I find the machine gets to different stages of the boot sequence fairly randomly. The most common scenario is VGA_LED red, and q-code 62. There is no picture on my monitor (no GPU, just hooked up to integrated graphics). Sometimes repeated rebooting, or clearing the CMOS, will get it to q-code 79. Sometimes the VGA_LED will go out and I'll get BOOT_DEVICE_LED on instead. Occasionally I'll get the ASUS splash screen with q-code 9C. Sometimes, I'll get odd artifacts on the screen, as below.
When I do get the ASUS logo with text saying "F2 or delete to enter BIOS, it's frozen here - keystrokes are not recognised. I did once in about 100 attempts get it to get to q-code 99 (the chassis fans started up) but again, it hung on the same screen.
As a final attempt to get some movement, I updated the BIOS (Z170-DELUXE-ASUS-3401.CAP) using a USB stick. It seemed to update successfully, but it just made the q-codes even more varied!
I would guess it is either CPU or Motherboard. Is there a way to determine which one?

Steps I have taken to try and fix it
I have already...
■ Removed all components and tried to boot with just CPU, 1 stick of RAM and onboard graphics
■ Re-sat the CPU and cooler, replacing the TIM
■ Reset CMOS. Several times. Also i've removed the battery.
■ Tried sitting the GPU in a different PCI slot
