    1. Double and triple check all the connections. Double check that the power-on signal pin on the motherboard is plugged properly.

    2. Try another PSU on that system and/or try that new PSU on another system, this would be a great way of verifying DOA.

    Did you plug the ATX 4 pin power as well?

    Are you getting any beep errors in the bios or can you not get into the bios at all?

    So did you plug in the ATX 4 pin as well?

    Do the fans spin at all (does it stay spinning and the screen is just black?), check if he has a microphone attached to the motherboard for beeping, some cases don't come with a beeping speaker.

    try removing stuff and testing them one by one. test one video card at a time, then start adding components until you get a beep or an error message. remove all unnecessary USB for now.

    what motherboard is this on?
