Ok battery out. Switch flipped.
if it boots up. Do i alt F10 to back it up.
Just to clarify mate it's the Z77X-UP7 which I'm looking at.
Try reflashing the same BIOS again then flip switch and try booting from main,if no go you might have to alt and f10 from back up BIOS
Tbh I think your problems are down to sb chip,they do have issues running well compared to ib CPU on z77
Are you using latest beta BIOS?
Try booting from backup and press alt and f12,I think that flashes backup to main,Idk why they don't use a single pull out BIOS chip like asus/asrock do,if bios fails you can pull out the chip and plug a new one in
Alt F12 just takes me to boot menu.
There should be an option in qbios to copy bios to and from main.
ok I got a reply from Stasio,he says its ctrl and f10 to flash the main bios with the back up bios version,though he hasn't tested this yet
