After changing the motherboard, VGA LED is on.

Hello,
I have read various posts about the VGA LED being lit.
However, I believe I have checked everything. I switched from an MSI A-520m A-Pro motherboard to my new MSI B550 Gaming Plus motherboard.
My configuration is as follows:
CPU Ryzen 5 5600
RAM 2x8GB at 3200MHz CAS18
GPU AsRock Intel Arc A750 8GB
Power supply EVGA 750W Gold
From the first boot with the screen powered on and connected via DP to the GPU, the VGA LED lit up, so I thought it was a bad connection in the PCIe slot. I removed and reinserted my GPU, but the problem persists. I cleaned the PCIe connector of my GPU, even though it wasn't dirty at all, but there was still no change. I then suspected a power supply issue, so I changed my power cables, using 2x8 pins for my GPU, and I even checked my power supply, but nothing...
I then thought about a BIOS update, so I copied the latest BIOS update for the motherboard onto a USB drive formatted in FAT32, but the LED still lit up.
I took my old GPU, a GTX 1660 Super, and the VGA LED problem persisted, meaning no signal to my screen.
I also tried booting with just one RAM stick and changing their positions, but nothing worked.
I have been careful to rebuild my PC, taking my time and paying attention to absolutely everything, but now I don’t know what to do.

Hello
If neither the Asrock nor the GTX 1660 works, it's a motherboard issue. Or maybe you’re missing something (connection, power supply?)
Try the graphics card in the other PCI Express slot.
Otherwise, the Ryzen 5 5600 has an integrated GPU, try without the 1660 or Arc by connecting the screen to the video output of the motherboard. It should display the BIOS.
Otherwise, post photos of your setup here.

Waiting for more answers; I attract trolls....
Hello,
Thanks for the reply. I forgot to mention that I tried the other PCIe port and that didn’t change anything. I checked the power connection, I unplugged and plugged it back in, but my card is powered because at boot time the fans start and then stop since the card is cold.
No, the R5 5600 doesn’t have an integrated GPU, unfortunately.
I'm attaching a photo of my setup :
ok...
Check that the motherboard is not in contact with the bottom of the case's basket (just in case a standoff is in the wrong place and is grounding with the motherboard circuits).
And if that's fine, that it doesn't work with the GTX1660 either... that's a bit worrying... it's either the motherboard (consider a return to the service center), or the power supply.
Are you sure about your power supply? Do you have another one to try instead?
Speaking of the support pads, do we need all the pads? Because I didn't have the necessary amount to put them in every place on the motherboard.
I'll check as soon as I get home tonight to see if it's not making contact with the case.
The power supply works, yes, I tried it with another power supply, a 650W one, but the problem remains the same.
Speaking of the support standoffs, is it necessary to have all the standoffs?
No, it's not mandatory; when we are lacking some, we need to distribute them according to the load points applied on the motherboard to avoid bending it while inserting the connectors.
What should be avoided, however, is positioning one in a location that does not correspond to a motherboard mounting hole. This risk exists with cases that support many motherboard formats.
Oh yes, you're right.
