Arduino nano cant be detected on COM ports

My Arduino nano I've been using for a few months without issue suddenly isn't able to be detected by my pc or laptop, I've tried using a different cable and it still cannot be connected, to my knowledge I've not damaged the board physically and don't know why it wont work.

Even weirder is that occasionally there is a connection and when I try to upload any code it compiles gets ready for upload then suddenly disconnects and gives an error saying "Failed uploading: no upload port provided".

If anyone has any suggestions on how to get the board to work with the COM ports again I will be eternally grateful.

Hi @the_bignoob

Try double pressing the reset button (two times in quick succession). This will place the microcontroller into bootloader mode. Just select the new COM port in the Arduino IDE and upload as usual.
