Help after lightning strike

Hello. Long time mk3 user.

I unfortunately had a lightning strike recently that smoked my PC's motherboard. I've replaced the board and rebuilt the computer - it runs great. Today I realized that my mk3 was connected to the PC during the strike. I can print from the SD card with no problem, so the printer itself is fine. However, I can't connect to the printer over USB. Here's what I've tried:

- installed USB driver, pronterface, and PrusaSlicer using windows install package

- verified the USB port on new PC i'm using works

- printed from SD card - printer is fine

- used a USB tool to see what's connected - the printer isn't

- checked PORTS tab of device manager for printer - it's not there

I can't detect the printer, and have manually tried typing in COM1- COM10 in Pronterface.

Any help or suggestions? Can I validate the USB controller is working?

Edit to add: When I try to connect to any COM port in Pronterface, I get this error:

Connecting...
[ERROR] Could not connect to COM1 at baudrate 115200:
Serial error: could not open port COM1: [Error 2] The system cannot find the file specified.
