No lights, no fans, no beeps — power chain from wall to motherboard, and the 30-second test that isolates it.

1. Verify the wall power chain

Plug a lamp into the same outlet, flip the PSU rocker switch on the back to I, and bypass power strips. Tampa summer surges kill strips while the PC is fine — confirm the outlet is actually live first.

2. Drain residual power

Unplug the power cable, hold the front power button 30 seconds, reconnect, and try. This clears the protective latch-up that follows surges and brownouts — the most common 'dead after a storm' fix.

3. Listen and look for the failure point

Fans spin then stop: likely PSU or short. Single click, nothing: PSU. Beeps: count them — that's the motherboard telling you RAM or GPU failed. No signs of life after steps 1–2 means hardware, not software.
