Hmm.. arduino powering up, but windows doesn’t give you the normal connection sound indicates the driver may not be working/installed… but the driver is installed because you were making cuts…
Very strange. I might try just the arduino in another laptop/computer and see if it works. If I were to guess, it will work and perhaps that means a problem on the original computer.. but it would be the first time I’ve seen an arduino able to damage a usb port… something could have also damaged the ch341 chip on the arduino, but that would also be a first for me.
When you plug it in, does device manager show that there is a device plugged in?
