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?

Shut everything down and unplug everything. Then reconnect and restart each component one thing at a time.

Sounds like a power issue, so note what happens for each component when plugged in and restarted, then come back and tell us what happened.

In all honesty, it could be a number of things and might be hard to pin down from a distance.
