New printer

  • disconnect the printer from the computer.
  • uninstall the print driver & delete the driver.
  • reboot the system.

Now start over and FOLLOW the instructions - - as I recall, the Canon pixma software needs to be installed BEFORE it is first connected to the PC.

Once installed you can then connect the printer and it will be found and usable again.
 
Hmm; at worst case (like even a shorted out USB cable), only the physical USB plug would be damaged - - and the PSU would easily survive.

Indeed. OP's wording isn't very clear on which component blew.
 
Before we get to troubleshooting your computer. Have you tried plugging the computer into a different outlet and turning it on?
 
Alright, well, in these situations it's usually the PSU. What kind of power supply does your computer have?
