PC booting with onboard graphics, ignoring the GPU

[Joffrey_1]

Hello everyone,

I come for your help because I had an absolutely impossible problem to solve since I changed my graphics card.

Let me explain,
I had a gtx760 asus and everything worked fine. Then, a few months ago, I bought an Asus 980ti Strix, and since I'm facing a strange phenomenon: the computer starts on the cpu graphics, and switches between the gpu and cpu on every restart. So basically, first start cpu, restart graphics card, restart cpu, restart graphics card, and so on.

I absolutely tried everything. Flashing an older BIOS reflashing the latest, clear CMOS, reinstalling an older operating system after totally formatting my ssd with gparted live, then reinstall Windows 10 again from my completely empty ssd, old driver installation, pci port change, power cable change. I also searched the bottom of the bios, I found nowhere a way to disable the onboard graphics. I tried to disable all the sharing between the cpu and gpu, disable anything that is energy saving (like ASPM), and the weirdest thing is that the bios saves everything except a setting. There is, in the configuration of the North Bridge, the primary display setting, and when I put it on PCIe, the computer starts on the gpu, but after a reoot, this setting goes back to auto, and this is the only setting that the bios does not save, but everything else, it saves. My components are a year and a half old, so I do not think the CMOS battery is dead, and more the time is correctly set and all other parameters are there.

Another weird thing is that when I access the BIOS when the computer starts (or restarts) on graphs of CPU, it does detect something in the pci port, but puts the link speed to x0. Against x8 when I go into the BIOS when the PC starts on the graphics card. It was as if it detected something but chose not to start on it. When the PC restarts on the graphics card, Windows only detects it in Device Manager, and when the PC starts on the graphics of the CPU, it does not detects the 980ti, but when it starts on the cpu graphics, the 980ti is considered unplugged. I also tried uninstalling the intel hd graphics driver but it does not change it still finds a way to start on it. I have all the drivers chipset and bios updated as well as the graphics card drivers. I also tried installing older chipset drivers, does not change a thing.

Another strange thing again, when I plugged the card for the very first time, no drivers installed, the computer has started directly on the graphics card. This issue showed up after installing the driver, and stayed when I formatted my ssd and reinstalled Windows. I also tried on another motherboard and it works well even after multiple reboots the display comes directly on the graphic card. I tried this on a motherboard with my ssd plugged it, so my system, but not sure the drivers have been recognized, since I had a strange resolution at this time.
I really do not know what to do to overcome it, though it does not seem to be a so huge problem. I do not know if there could be a hardware issue since my motherboard reacts well with an older card, and a newer motherboard reacts well with my graphics card, (without drivers it seemed). But I do not tend to think that drivers are involved since nvidia know what they do, and because of the fact that the problem was still there after two time of completly formatting my ssd.

Other information: The graphics card is plugged into a PCIe 3.0 x16 and runs at PCIe 1.1 x8 and according gpu-z, even while doing the render test.

I consulted many forums where some people had a similar problem but no one had a solution, so if anyone has one here, it would be great because I am totally lost in all this mess.

My setup:
Intel Core i7 4770k
Asus Z87-Pro
Corsair Vengeance 16GB DDR3 1600MHz CAS 9
Asus Nvidia GeForce GTX 980Ti OC Strix 6GB DCIII
Corsair RM850i
Sandisk SSD Plus 120GB
Seagate Barracuda 2TB

Thank you to those who will see and reply to my message.

Tried NVIDIA experience? Didn't read the whole thing, but I think it might work. Not too familiar with recent GTX cards ;-; but I think this might work

Yes I have of course the nVidia GeForce Experience, it is with this that I keep the drivers up to date, but when the pc starts on the onboard graphics (so the cpu) it says you need a nVidia GPU to launch GeForce Experience which is not surprising because Windows does not detect the card and thinks it is unplugged

usually if you install a graphics card it will set it as default, but sometimes you will need to go into bios and turn off the integrated graphics and set the pci-e graphics under display adapter. one problem I have seen before is when the individual has a display cable connected to the video card and the onboard connectors at the same time, this will force the system to boot to the onboard or apu graphics by default. if you only have a display cable connected to the GPU it will boot to the graphics card

There is nowhere in the BIOS where I can disable the integrated graphics, and when I plug a cable only on the gpu, there is just no signal, I have to reboot to get one.
Also if I hit reset just after powering on the computer, it seems it considers it as a reboot because it starts on the gpu

did you clear the CMOS prior to booting the GPU with cable connected only to GPU? unfortunately that probably the only thing I can think of unless you can contact the MB manufacturer. a lot of times they will help even if you do not have a warranty, but does very from company to company

Yes I did, and it boots up with no image, screen saying no signal.
I talked to Asus about this yes, and after telling me to try things I already tried, they told me to send back the gpu as if it was defective. But I think none of my components is defective. I don't know the symptoms of a mobo or gpu that is defective, but mine seem just as if they were non-cooperative
