z77 bios corruption help

[lemming3k]

Hi,

I recently Qflashed the bios from F10 to F14 due to stability issues with a couple blue screens that I was hoping might be solved. Since then I can boot the machine but I'm unable to get into the bios, Qflash etc options on start up - I just get a blue screen with a black bit at the top saying Gigabyte Uefi Dual Bios.
So far taken the cmos out and attempted to get into bios after that but same issues. Reset to optimized default settings but the issue persists. Is there some way I can flash this without going into Qflash? Seems like I'll have to RMA the board anyway so anything's worth a shot.
Also would be interested to know if this is a known issue with these boards as I've seen a lot of people having problems!

Hi

Are you using the onboard graphics or a dedicated video card ? Try using whichever one you are not at the moment.

Hi, I've tried both but neither can get into the bios. Not being able to change the boot order I can't seem to boot from a USB stick either to try and flash it again.

you can remove power cable of sata hdd; it will boot from  usb drive to flash bios

Unfortunately it won't boot from it without going into the menu for selecting the boot device - at which point the screen freezes(obviously not the keyboard because i had to press F12 to get into the menu).

Try this then. For the Z77/X79 motherboards use ALT + F10 at bootup instead.

Boot from the second BIOS, if you can't boot to windows on the main one, then ALT+F10 on startup from the second BIOS on a reboot from windows, this will reflash the MAIN BIOS with the backup BIOS you'd be booting from.

That's what I would expect from a dual bios, but it doesn't seem to do anything(nothing happens, it boots through but nothing has changed). My windows drive also seems to be having issues now opening files/running programs. Seems with a corrupt bios I can't reformat it correctly either so I'm down to just Ubuntu. Looks like all I can do is RMA the board.


EDIT: should also add I have tried the HD in another system and it's fine so it's the combination of this drive and bios/motherboard that's causing issues.

Well things have got much stranger.

Tried removing the CMOS - no change.
Was getting ready to RMA it, took all the cables off (CPU fans, Power LEDs etc) - Then had to put them all back in as my 3TB drive isn't recognised in my old system and I needed to back some data up. I hadn't removed the RAM, GPU or CPU at this point just the silly cables.
Tried the bios for some reason and it worked!

It's been running fine for 4 days, slowly building up the drivers and updates, able to get into the bios, confirmed F14 was installed on it and it's still detecting everything correctly - then today it's gone back to the black screen AGAIN! I booted up and SP1 was waiting if that's possibly relevant. I'm guessing it's a driver/software based issue but I have no idea what the conflicting object could be???
