STM32F429: White screen, flashing COM LED

Hi guys, total newb question here: A few weeks back I got a STM32F429.  Immediately when I received it, I plugged it in and played with the demo software which seemed to work fine.  Busy with other things, I stored it away safely for the last few weeks.

 

Just today I go to work with it, plug it back in and all I get is a white LCD screen, the COM LED is flashing periodically and the power LED is continuously on as shown in the image below.

 

Despite having the ST-Link/V2 drivers installed, Windows does not acknowledge the board as a plugged in USB device.

 

Searching this forum and Google have not provided me with any leads.  Anyone have any ideas?
