hello friend i have nm-a804 mother board which i an facing problem. When press trigger mb on and off all supply generate.
any have solution and schematic

Schematics are not available for this board, you'll have to troubleshoot it without one.

I don't understand what the problem is. Can you elaborate a little more on what you tried to do and what exactly isn't working? Please don't respond with short sentences, the more you write, the easier it will be for us to see through the bad translation.
