Computer wont boot in Windows after updating GPU

HI.

Changing out my old GPU, a GEforce 1081 Ti for a new Intel ARC B580.
Motherboard is a MSI Z490-A PRO, power supply is 850W, Windows 10.

In the past I have just removed the old card, put the new one in and rebooted, then installed new drivers.

That didn't happen this time, I get the BIOS logo flash on the screen and then the computer stops, it doesn't boot into Windows. I can press 'delete' and get into the BIOS though so something is working.........

I then updated the BIOS, it was a bit old. No improvement. However if I remove the power from the GPU the computer does boot into Windows, I can hear that, there is just nothing on the screen of course.

I did a BIOS reset, removing the power cord, the onboard battery etc etc.

No improvement. I did notice though that when the computer stops so do the fans on the GPU.

There are no onboard graphics on this motherboard. I have tried all the outputs from the card, no difference. There are a series of LEDs on the motherboard which come on during booting, they go through the same sequence when it fails as when it boots properly.

If I put my old GPU back in everything works as it should.

Any ideas as to what I can try next.

Thanks for the reply.
Yes Windows is on 22H2

No I haven't removed the Nvidia driver, I don't think the computer gets that far before it stops, so didn't think drivers would be the problem, but it was on my list to try. To be clear I see the flash of the BIOS logo screen and then that's it.

The power cable, there is only one 8 pin socket on this B580 and I have a cable which comes straight from the power supply to it.

Yes the card is brand new. I do have an email into Overclockers but they say it might be 10 days before I get a response.

I can't try it in another computer it's a long card and it wouldn't go in anything else (small cases) unless I took the whole thing out of it's case.

Sorry to all I've been away for a few days.
Anyway thanks all for the info and help.
Just to let you know it is all working now. After trying various things and pulling my hair out I flashed the BIOS again, with the same file as I'd used before and now it all works! Just to confirm Resizeable BAR does need to be enabled.

So not sure what was wrong with the initial flash of the BIOS, after all the old video card still worked as it seemed everything else did, but you live and learn.

Thanks all.
