Arc a750 prevents PC from booting at all

[Boune]

Hello, I just bought an intel arc a750 for my pc.
The problem is after plugging in the card there can be those two following scenario:
The first, the pc do not boot, I can’t even access the bios and the only thing happening is that I have a black screen with a solid white dash, also the EZ debug led for VGA of my motherboard is on. And peripherals not working

The second, I tried without plugging monitor, the keyboard and mouse’s lights are on but when I plug a monitor after that, there’s no signal. And I can’t hear the boot sound in my headset


Here is the full confit:
Motherboard : MSI B365M Pro VDH
Processor : intel i5 9400f
Ram : hyperx 2x8go 2666mhz
PSU: Corsair cx650
A Samsung 500gb sata ssd

I tried with another psu (a 650w advance) and it didn’t work either
When I plug my former graphic card, everything is working perfectly, it’s a gigabyte nvidia gtx 750 ti.
I removed nvidia drivers from my pc

My bios version is E7C39IMS.142 which is at this moment the last update
Resizable bar is on
Fast boot is off
Bios is in UEFI mode

I tried to disable rebar to see if i could get it to boot, but no success.

And i can't install arc drivers as i can't plug both graphics card (only one pcie) and the installer doesn't work without the card in.

I suggest that you check out these articles for some helpful steps:

Also, share the ssu logs of your system so we can review it. If that’s fine with you. Here’s the link on how to do it: https://www.intel.com/content/www/us/en/support/articles/000008563/ethernet-products.html

tried what's written in both articles (except driver because as i say i can't install them except if you have a way to force the install), didn't work

can't run the ssu logs with the intel arc installed, as i cannot boot with it as said in the original post, so i did it with the gtx 750 ti, if it can help find the reason, i don't know how to review it so here it is.

The issue could be related to the compatibility of your motherboard, processor, and the arc graphics card. I have reviewed the supported hardware configurations and system requirements, and it seems that your current setup does not meet the minimum criteria. You need to have at least a 10th Gen Intel CPU and an Intel 400 Series motherboard with Resizable BAR support enabled. You can find more information in these links:
