I am using an Arduino purchased Nano using the off line Arduino IDE version 1.8.12. The port selection function under Tools menu of the IDE is greyed out. The PC does not detect the Nano, there is no ding dong when plugging the Nano into the PC USB socket. The load LED is flashing. The USB device on the Nano is an FTDI device with markings 1917-C, F53773G1 and F1232R1. Since there was no communication, PC to Nano, I installed the Port (COM and LPT) manually as a Legacy device and find there are four drivers within the Arduino drivers folder. Which should I use? Is there anything else I should check? I understand I need to use the old bootloader when I get to uploading a sketch.

Make sure the USB cable is completely plugged into both the Arduino board and the PC.You may have a damaged/defective or charge-only USB cable. Try a different cable.
Either of the above can result in the power connections being made (and thus LED lights on the board), but no data connections (and thus no port for the board).

It sounds like you're using Windows. Do you see a new device appear under the "Ports (COM and LPT)" section of Windows Device Manager after you connect the Nano's USB cable to the computer?
