Question MSI motherboard reset to default, power to the USB ports and no display feed

Apr 10, 2019
So my friend has a computer with an MSI Mpower Z87 Max motherboard. He wanted me to help him restore his bios settings to normal so he asked me to help him ecause he is not very good at english. I went into the BIOS of his computer when booted, went into the settings, and when asked till save changes, I chose something in the lines of "Reset to Default", so I pressed the button on the computer rebooted. Problem is, it gives no feed to the display and no power to his USB ports, because his mouse and keyboard doesn't light up. We tried turning the computer off and on again, still no feed or power to the USB. How can I fix this?
