I ordered a Arduino Nano V3.0 Compatible ATMEGA328P with FTDI FT232RL
5V 328. Whilst waiting for it (Win 10) I installed Arduino IDE V1.8.8
and had a quick look, but didn't change any of its settings.

The Nano arrived this morning, so I plugged it into the USB, it lit up
then sat flashing two of the green LED's with a not flashing green
power LED. Win10 bing, bong as its plugged in and removed.

Since then I have been struggling to upload a simple program on it
using IDE, but each time IDE compiles OK, then complains 'avrdude:
stk500_getsync() attempt 10 of 10: not in sync: resp=0x00 An error
occurred while uploading the sketch

So far as I could tell, I have installed a driver for it in W10, and it
ought to have a port called 'Arduino', but it doesn't. Device Manager
shows in ports 'USB Serial Port (COM3) which appears and disappears as
the Arduino is plugged in.

Following the procedure described to install the proper driver, it
crashes W10 and forces a reboot.

Clicking 'Board Info' produces -
BN: Unknown board
VID: 0403
PID: 6001
SN: Upload any sketch to obtain it

I have the IDE Tools settings as -
Board: 'Arduino Nano'
Processor: 'AT328P'
Port: 'COM3'
Programmer: 'AVRISP mkII' I have no idea what this ought to be set to..

Help please?
