VC709 blue screen - missing UART

I have a VC709 connectivity kit. It has been working fine but upon connecting the UART-USB cable to my computer it caused a blue screen of death. Upon restart of the computer the FPGA does not appear in Devices and Printers. How can I resolve this? I installed the driver on another computer and tried a different cable and nothing. I'm hoping the UART circuit is not damaged.

Re: VC709 blue screen - missing UART

Please do some electrical testings on the boards to confirm its operation. 

Was there anything different with the UART you were testing? 

Are power LED's glowing indicating power is okay?

Re: VC709 blue screen - missing UART

Does the FPGA display in hw manager? Do the LEDs show a power issue?

The LEDs show no power issue. DS1, 14, 16, 17 and 18 are all green.

It appeared in hardware manager before but does not appear anymore.

Re: VC709 blue screen - missing UART

There are no debugging steps for the UART port. The JTAG works fine.
