The RAMPS is plugged into the Arduino. there is a green flashing LED on the RAMPS near D10. On the Arudiono, a red LED is permanently on, near the middle of the board.
A green LED next to the red LED on the Arduino is flashing in time to the LED on the RAMPS (which I take to mean they are related).
If I uninstall the mega 2560 driver and then re-scan for ports, Windows automatically installs its own drivers and finds the COM1 port. When I open the Arduino software, it tells me there is a Mega 2560 on COM1- see attached screenshot.
If I try to flash the Marlin firmware, I get the following text in the bottom screen...
