My computer is old and I dont use it that mush only for recording music it stop coming on how do I get it to come on again?

make sure the power cable is connected perfectly if connected well try resetting the ram of your computer then also don’t work take out your power supply and short the pin green and any black wire and u should see the power supply fan is running………. if running also make sure that ur mother board is getting the voltage supply try disconnecting the motherboard cable and reconnect it again……………… Hope its work… try it and FIXIT
