Hello. My computer is Z77X-UD3H/3770/Kingston HyperX 8GB 1600Mhz.
There is the exact same problem.
Then the bios issues started, only thing I saw in bios was black border with EUFI Dual Bios text and blue background.
I have not completely figured out, but it seems to be related to USB ports.
I have the freeze occurred when I connected the Logitech G25, even in USB2 ports.
Therefore, I recommend disabling the extra usb devices and / or swap connected usb devices for different ports
, use native ports (which is closer to the LAN), not VIA, use USB2, which is on the front panel. Something like that.
Something ill-conceived from the USB ports on this board, waiting for new firmware, current firmware is obviously raw.
I would say more, I have had problems with SATA2, when it was connected DVD-RW, a computer was loaded on a minute longer than usual, I turned off DVD-RW. Nobody is not writing about it and in the support service is not responding.
In general, have to experiment with connecting / disconnecting devices USB / SATA to solve such problems.
P.S. Attention! Bad English :-)
