There are a number of similar threads with no answer that has worked for me.
My PC's monitor was asleep. I clicked the mouse to bring wake it and the PC shut down. It would not power back on. The fans would spin briefly and then nothing. No POST; nothing.
Thinking it was the power supply, I "rebuilt" the computer in another case with a known good power supply (checked with a power supply tester). Same problem.
Thinking it might be the motherboard, I swapped it out with a new one (same model and revision), in the new case. Same problem.
So, I think I've eliminated the power supply, motherboard, and power switch connector (swapping cases).
I've plugged the computer directly into its surge-protected power strip and directly into two different wall outlets. I've pulled the RAM sticks and tried each one. The motherboard has on-board graphics so there is no graphics card to pull. None of the PCIe slots are occupied. Still no luck. I'm down to the CPU. Will a bad CPU give this failure?
