Computer wont boot in Windows after updating GPU

[JohnGPUK]

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.
