Ok, so a quick explanation.

Was playing a game today and the computer just powered off without warning and wouldn't come back. I get about 1/2 second of fan and RGB lighting then it turns off again. This was part of my troubleshooting:

1. let it cool off in case something over heated. -no change
2. unplug from the wall, cycle the power switch on the PSU - no change
3. pull RAM, try different sticks in different slots - no change
4. pull CMOS battery - no change
5. unplug all non essential components - no change
6. try a new PSU (what you see here) - no change.

At this point I'm totally stumped. If my mobo dead? CPU? I'm going to pull off the AiO and reapply thermal paste just to be sure, but I should be able to post even with a bare CPU  right?

Edit: there was no popping sound, nothing smells or appears damaged so I dont think I lost a capacitor or anything.

Edit 2: ended up swapping both CPUs and now both computers work just fine. I'm going to assume the problem is fixed and stop fucking around now.

Could also be a dead gpu as well, I once had the same thing happening. Take the gpu our and try again
