hello there, i have a B450M-Pro4 board here that wont power on :-(
3.3V on PowerOn Pin is ok, but when i pull down - the system wont power On. The SuperIO (NCP...) will not pull low the PSON pin, so the powersupply will not shift in on state.
When i manual pill low the PSon Pin - the powersupply starts and all phases works, voltages are all in rage, but board will not boot. When i leav the PS on Pin on ATX plug (the green wire) the board goes instantly off.

Error happens after ram remove. After ream remove - the board was in this "dead" state. But what can be happened here? What can i check?

наличие или отсутствие памяти на включение не влияет.

Asrock boards without a processor do not turn on. Do you check with or without a processor?

Computer components are sensitive to static electricity. Before touching any of them, touch the power supply housing to discharge static charge from your body.
