Got a new motherboard (z77a-g45) which I have flashed to the latest bios using the msi USB tool from the forum and cleared the CMOS.

Upon reboot I enter settings, and set bios to default optimal, save and exit and reboot.

If I change nothing it will boot to windows fine, if I change the bios settings (boot order, enable windows 8 features etc) upon reboot it will boot into the efi shell.

The only way to get out of that is to reboot.

Upon reboot and pressing del to enter bios settings the bios screen immediately freezes (no mouse or keyboard control).

This has happened twice, I even reflashed the bios to be sure.


Please help.
