Hardware:
Motherboard: ASUS P8Z77-V Pro
CPU: Intel Core i5 (don't remember exact model)
CPU Cooler: Corsair Hydro H100
PSU: Antec 850W
GPU: ASUS model GTX 1070.
Memory: 8GBx4 Corsair Vengenace RAM.
PC was and has been working without issue for over 1 year. Last night while watching a live stream the PC shut off abruptly but nothing else in the room lost power. I unplugged the power cord and plugged it back in and powered it on and heard a single click but nothing came on. USB devices were still receiving power (keyboard with backlighting still backlit.). The motherboards LED light is active. I press the power button and the fans connected to the CPU FAN connector jump, the light on the Corsair H100 waterblock flickers on, and there's an audible click, then an immediate shut off.
I opened it up and looked for any stray metal or anything thinking there might be a short, but didn't notice anything. I took out the GPU, same thing. Took out the memory stick by stick, same thing each time. Unplugged both hard drives 1 by 1, same thing. Unplugged the leads the connected to cases front panel USB connectors, same thing. Took it all the way down to just the POWER SW lead, the CPU, the CPU Cooler, and the PSU, same thing. The only other PSU that I had available to me was an older Antec 650W (I don't have the tools to test this PSU and it's been sitting in the garage for 2 years at least) which I connected and the same thing occurred. I unseated the mobo, inspected underneath it, reseated it and the same thing. I removed the CPU cooler and tried, same thing, and same thing after re-seating it.
That's the extent of my troubleshooting and I just wanted to see if I missed anything before buying a new motherboard, processor, and RAM. Any insight is appreciated!
EDIT: The secondary PSU that I tested it with was the last step, the original was connected during every other step.
