No POST, new components

Wizaaard · January 30, 2019

System began inconsistently crashing during Overwatch, at random intervals, and then while I was not gaming. Eventually would not POST at all, but does power on and spin fans. Reduced system down to PSU, mobo, CPU, 1 stick of RAM. Replaced the PSU first (new), no improvement. Replaced the mobo with the same model (refurbished), no improvement. Bought a new CPU, no improvement. Tried each of my 3 sticks of RAM in each of 4 slots, no improvement. Cleared the CMOS w/ battery remove / jumper short, no improvement. Attempted ASUS MemOK! button, no improvement. DRAM light was off. Just to check, I rebuilt using the old mobo, DRAM light would be on. Attempted to use the ASUS MemOK! process with old mobo, it would cycle through all three blink speeds, and then remain solidly on. Switched back to the new mobo, DRAM light is still off, still no post.

Ran through the list here, no improvement:
