Gigabyte MA770-UD3 cannot enter Bios setup

Guys,

Tried everything I could find on this and other forums to make possible entering into my Bios setup. I have Gigabyte MA770T-UD3, rev 1.5 and Bios version F10 and whatever I tried by hitting Del key during boot I got black screen with cursor blinking on top left corner. Yes, I tried CMOS reset, battery pull out, jumper on Bios reset, disconnected HDDs and use only my keyboard PS/2. Fast startup turned off already in Windows 10, motherboard does not have fast boot option, meaning I have a plenty of time to press Del key.
Boot setup never came up.

If someone have some tricks more to propose I would be very grateful or some working Bios fimware F8 or F10 for this motherboard. I presume that my graphic card Radeon R9 280 makes a trouble to Bios setup but I do not have older one to try.

If you can't get into the BIOS with the drives disconnected, it's obviously not a Windows issue.

Do any of the other hotkeys do anything? Startup Screen - Gigabyte GA-MA770T-UD3 User Manual [Page 34]

Too bad that you have no other graphics card to try, and that the board has no onboard graphics.

I have done all re-flashes, couple of them, using Q-Flash, hitting End key during boot. All of them passed successfully. But, the problem is that in BIOS settings (I edited this F10 version), where PCI Video output is Disabled by Default and, therefore, hitting Del key to enter Bios goes to some video signal, who knows where. I saw that in editing BIOS with some DOS tools, but I am not brave enough to compile updated version of BIOS with corrected PCI video output. That is why I am asking for some modded version of F10 Bios or even F11c but with corrected video output for newer video cards in PCIe slot. Or some other trick.

Do you have another keyboard handy? I recently had problems getting into the BIOS with a fancy RGB keyboard hooked up. Grabbed an el cheapo USB keyboard and was able to get into the BIOS.

It wasn't initializing the fancier keyboard fast enough to accept input.

Thank you for your reply. My keyboard here is Chicony from 1995, PS/2, which I keep because of memory to my friend. It is very old and simply keyboard. Do you have any other suggestions?

I still think it is a matter of newer graphic card and disabled option in original Bios for PCie graphic cards but I do not know how to change it.

Did you ever load the BIOS defaults? Also ask Gigabyte support who will reply even for old products

Thank you @StaveC and @bro67.

I have already done Restore to Defaults function using Q-Flash menu where settings Load Defualts were used. I have always done flashing BIOS by Q-Flash through BIOS menu, pressing Del Key without wanted results.-

At the same time, I have old Chicony PS/2 keyboard which I use without any adapters.

That is why I am asking for working BIOS since this one F10 cannot initialize newer graphic cars (I edited BIOS file and saw that PCI Video output is Disabled) and make my BIOS settings. I re-seted it for couple of times alraedy but without possibility to enter Bios settings menu.

Is there anybody how can share older F8 Bios or some working solution?

Thank you guys once again.
