GA-Z87-D3HP F5 Bios - Graphics card problems started!

[jackzonztyl]

Hi

I flashed latest availible bios F5 (without letter) and rebooted everything looked oke after a reboot my monitor losed signal (HDMI)
connected to my sapphire 7870 xt with boost and my graphics card works fine.

with VGA i get signal but only the logon screen everything before that is black?

 i deleted my driver (+left overs) and re installed them but without luck

i flashed F4 back but nothing changed.

on the change log they said that pci-e compatibility was improved

and now the bios is removed from the website i only see F4 why is that?

is there going to be a fix? does gigabyte know this problem

i cant open my case because i will void my warranty
so i cant clear cmos 

motherboard: GA-Z87-D3HP
i7 4770 / sapphire 7870 xt with boost
corsair 16gb ram

*all stock speed

Same problem here.

My mobo is a GA-Z87MX-D3h.

Could you find a solution?

I don't know anymore how to procede.

You  are the only one that are suffering the same problem.

Yesterday, I tried to put an old Geforce 8600GT and the gigabyte (UEFI) screen showed up.
But, the problem persists with the onboard graphics and HD7970.
