Hello everybody!

I have a very odd problem. After a month of vacation I started my PC and everything was fine. after a while surfing the web I did a restart, I can't recall why, but after that only one of my two monitors had lighted up. So I restarted again, but nothing changed. After some search I saw the error 43 displaying in my device manager:

"Windows has stopped this device because it has reported problems. (Code 43)"

I googled for solutions and tried the usual stuff:
Restarting
deinstalling the driver with DDU and install the newest driver
deinstalling the driver with DDU and install an older driver
in safe mode: deinstalling the driver with DDU and install the newest driver
installing a different graphics card to check the slot (it's fine)
updated the BIOS

I wanted to try the card on a different system, but I have to update the BIOS on it and I never did it on an older motherboard.

My system:
CPU: Intel(R) Core(TM) i5-4670K
GPU: GV-N970G1 Gaming-4G
Motherboard: Asrock Extreme4 Z87

After a reset of the MB, the PC doesn't wanted to boot. Later I found out that's because I activated the option "Ultra Boot". Neither normal nor fast boot will work, so I guess it has something to do with it? I thought about flashing the vBIOS to another stock version of it (I did not alter the current version), but apparently vBIOS is just about the min's and max's voltage of a card.

In the device manager under Properties -> Details -> "Status" are the following values:

01802400
DN_HAS_PROBLEM
DN_DISABLEABLE
DN_NT_ENUMERATOR
DN_NT_DRIVER



Does anybody have a clue how to fix this or has heard of it before?

EDIT:
I updated the BIOS of another computer and the card works just fine there. So I got a problem with my MB or it's the graphics card..

After doing some tests yesterday I found the solution. The BIOS of the graphics card was faulty. I dont't know how or why. I upgraded the VBIOS as suggested by Gigabyte (there is a PDF with simple instructions) with an .exe for both DVI and that was it. However, to get to this point was horrible.

As mentioned before, the GC worked on another systems DVI-D port, without a problem. When I plugged the DVI-I !!! port of my main system it didn't work. The system didn't want to boot. I had to start my main system without any monitor attached to it and it booted. Then I could plug in the DVI-I cable and had an output.

With GPU-Z I looked up the kind of VRAM built into the GC and loaded the appropriate file, for me it was...

I tried to update Windows and did a fresh install. Both solutions didn't help. It seems the problem really originates from the motherboard. Tomorrow I can test the board with a 1070. Maybe it has something to do with new graphic card architecture.
