hi, we watched your video, it's RGB-cycle logo while powering up,
which can only mean the connection between cross hair and PC(console) is not good.
you can try the following solutions:
1. try a new and qualified usb cable for conecting cross hair to PC(console)
2. try repairing firmware of cross hair by following chapter 4.2 in "CrossHair-UserManual"
it can also be caused by a defective MINI usb port on cross hair,
if it is so, you will have to contact the seller and request for after-sale service.
you proivde one-year warranty for all customers.
