"Also tried switching little red switch in back from 115 to 223 and back"
Not overly dangerous when your mains power supply is 110-120V but if you were in an area where mains supply was 220-240V and switched a PC powersupply to the 115V setting you would blow it up.
When the fuse in your home switchboard blew it might have allowed a high voltage surge through your PC. The powersupply may or may not be the only thing damaged but is the place to start troubleshooting. Without a known good powersupply you cannot begin testing for other failures.
