I accept no responsibility for any damage to anyone’s computer by following this.
It worked for me, but please if you are unsure do not use the utility in the optional part as it is dangerous. (no really it is)
Best case it works! Worse case you need a new pre-programmed Bios chip.
Easy Bit
Have You updated your Management Engine FIRMWARE to 8.1 (ships with 8)
IntelME81_Updating_Tool_V10001.zip (Asus using same link for all Z77 Boards).
After doing this you MUST reset (via Jumper) your Bios & after booting normally, reboot to bios and check your settings(as it can sometimes cause issues (corrupt/missing options))
[optional]If you still have M.E. issues or corrupt options : (the hard bit)
Download latest Bios
Download this BIOS flasher:
http://www.ami.com/?AMIBIOS_and_Apti...te_Utility.zip
Extract the zip, navigate to: AMIBIOS_and_Aptio_AMI_Firmware_Update_Utility\Aptio\AFUWIN
Depending on your OS architecture, either open the 64 or 32 folder
Open the zip in the folder you just opened
Extract the folder within the zip
Either restart your computer or close every application that's running,
this step is important!
Return to your extracted folder and run AFUWINGUI.exe
save your old bios as a backup, just in case
Click "Open" then browse to the latest BIOS file
Under the Setup tab, tick the "Program All Blocks" check box (see below image)
FLASH.... (can take some time as it is a full bios rebuild)
Hold breath.....
BOOT
Profit (hopefully)
NB. You may have to fully reinstall windows for that fresh feel but you should be able to to see if it worked.
