Can't recognize on my PC

[herm1ne]

After upgrading Cross Hair FW to the v4.0.0+, my PC no longer recognize the Cross Hair.
I followed upgrading steps and it seemed the upgrade is done without error.
There are 2 beeps and then RGB cycle... I followed all steps stated in Warning and Solution PDF.

When I use another computer to connect Cross Hair, the manager successfully recognize the Corss hair first time but after that the same thing (2 beeps and RGB cycle) happens.

When I try to reset the firmware by holding the button, it does nothing.

Would you help me out?

seemingly, it's caused by bad connection between cross hair and PC(cosnole).
please try another similar USB cable or buy a new one to do the connection.

or your may also try connecting cross hair to console for a comparing.
do not plug any usb devices to cross hair while doing that.

Thanks for the reply. 
After changing the cable, the Cross Hair works like a charm.
