allready barboned, no hdd, one dimm , first PCI slot gves a vga bios error, so using the second one, bougt the whole thing today after old PSU blew whole case.

nowhere in the VERY HELPFUL manual does it explain how to clear cmos, there is a button, but the use of the button is beyond me.

I pressed it or something and the power light flashed for a bit then was solid, i assume this means i correctly cleared it.

same problem .

My Setup is the following

Mainboard: Gigabyte X79-UP5-WIFI
RAM: 32GB (8x4GB) Corsair Dominator 1600
CPU: i7 3930k C2-stepping
GPU: evga gtx 770 Superclocked
PSU: Corsair AX760
SSD: Intel 520 Series 180GB
HDD: 1TB Western Digital Green
optical: some LG Bluray Drive

what i have tried is:
-clear the cmos
-made sure all cables are connected properly
-used only 4 ram modules and used only 1 ram module
-unplugged all hdds and drive

It did change absolutly nothing, the situtation is exactly as described by the thread starter...
And i dont know the bios version, since i cant even get to the bios, it freezes at the splashscreen and reacts to nothing besids restarting with ctrl+alt+del...
any suggestions?

probably you don't have another cpu, memory model and psu to confirm ..
try to make your system boot up from backup bios?
a small screw driver touch main bios pins (around main bios chip, don't touch any other circuit on the mb) and try to make it short (make sure not damaging any real pin) and there may be chance to boot up from backup bios).

Exact same issue here. I have the x79-ud3 mobo but I have exactly the same gfx card as you. When I swapped gfx cards to my old one it worked again. For some reason it doesn't seem to like this new card =S

I am having the same problem over here and maybe it could be that the backup BIOS is not compatible with the GFX card and in my case with the XEON processor. I had a perfectly working computer but after change something in BIOS regarding UEFI Bios compatibility the system hanged with a noise in the boot process. This event and the fact that I've tried to use the backup BIOS brought my system into the state described in start of this thread. I think that I'll have to find another processor to use, a core I-something, then update de BIOS again so it become compatible with XEON and GFX card again.. so, a pain in the neck all over the place!

I had issues with AMD R9 270 and 290x VGA cards on two X79 motherboards, ECS X79R-AX v1.0 and Gigabyte GA-X79-UD3.
First mobo doesn't start if VGA card has UEFI-enabled BIOS, after re-flashing VGAs with disabled UEFI BIOS part it works well. Google for "HD7xxx Series UEFI Patch Tool"
Gigabyte mobo won't boot with UEFI VGA BIOS enabled AND mb bios newer than F14. With old 8800GT it boots with any mb BIOS, even with latest F20. If both 8800GT (in 3rd slot) and 290X (in 1st slot) present, motherboard boots successfully to Windows and 290X is not detected. So, something is broken in BIOSes after F14, trying to identify the reason.
