I need help with my pc please

My fuse blew to my home and i turned everything back on. Now my pc turns on but now I can't get my display to work aswell as when I plug stuff into the USB ports they won't turn on or even light up. Only thing that will light up is my keyboard. My keyboard turns on when plugged in to any of the USB ports. But my controller, mic,etc won't turn on and my display wont work. AAy idea what to do?

Too many possibilities to diagnose this! Check all connections, remove as many peripherals as you can, and if you're proficient in doing so, as many removable internal components as you can one at a time and hope it's not the motherboard or data drive that's broken. Initially check it's not a faulty power supply unit by swapping it out for one that you know works.
