OS not booting after installing new GPU

Recommended Posts

Posted · Original PosterOP

My computer specs:

CPU: Intel i7 2600 @ 3.4 GB

RAM: 3x 4 GB DDR3 @ 1333 mhz

Mobo: Intel Extreme Series DP67BG

Storage: 1x SSD - 2x HDD


PSI: Corsair CX 750W


I bought a new gpu, an RX Vega 56 Air Boost OC 8 GB.
I did what you would all recommend, restarted into safe mode, launched DDU and cleaned and shutdown the pc. Swapped GPU's and it got stuck in Intel's splash screen with code EB, it wouldn't even let me get into the BIOS. Swapped back to my GTX (because that one keeps letting me boot), Restarted the CMOS by removing the battery, the power cord, and all of that. Also got in the BIOS and loaded default config just in case, saved and exit. Swapped GPU's again. This time it didn't get stuck into Intel's splash screen, it gets stuck right after that. Exactly right before it starts loading windows. All I get is a black screen and a "0" at the bottom right of the screen. I thought it wasn't booting from the SSD so i went for a selective boot and manually selected the SSD. With that, it gets stuck with the boot menu and a "0" at the bottom right (yes, it just appears).


I tried using the other PCIe slot, updating the BIOS (which is still pretty old - 2012), plugging different cables for the power connectors and made completely sure everything was well connected to the motherboard.


I'm at a loss. What can i do? i'd appreciate any help.

The board may very well not be compatible with the gpu.

Few realize that pci-e is not 100% universal thus boards will have bios updates for gpu's occasionally. With that board being 8 years old it's not a common configuration people will be running.

Basically you'll need to stick the gpu into a different board at this point to make sure it's not the gpu at fault.

That's nonsense.

PCIe works way better than AGP before it did.

There might be some BIOS Issues though.

That can be rectified with a BIOS Update.

You could look at the CPU-Z Screen -> Motherboard. There you can see the BIOS Version of your Board.

See the Link I posted, check if that is already on the Board, if not do it...


Also there are no known problems with RETAIL Hardware and VEGA...

Only old OEM stuff, where they might have messed up the BIOS...

Are you booting with UEFI?
With secure boot enabled?

If you can, then you should.
