I got a h510m pro-e with an intel i3-10105F and a single module 8 GB DDR4 RAM . These set-up was chosen us a cheap upgrade for a system where an old MSI N9400GT-MD1G will handle the graphics. But, the system won't boot and VGA debug LED turns on in white color. Of course no output goes towards the monitor. But the monitor detects when the cable (VGA) is connected to the card. The MSI N9400GT-MD1G was tested with the previous mobo it was installed and works properly. I plan to test if the mobo works with an RX 460 and if it doesn't I will asume the pci slot is broken.

Can the MSI N9400GT-MD1G be used with the above components? Is there a setting or bios update that will fix the issue? Or should the GPU be replaced (in this case can you suggest an alternative with less than 100$)?

Replace the GPU with a newer one the MSI N9400GT-MD1G is very old and will have no UEFI GOP support. test with the RX 460 as that should have full GOP supported VBIOS on it

Well i tried both an Asus GeForce GT 710 2GB (pci 2) and an Gigabyte RX 460 (pci 3). But the same problem occurs. The computer starts but the VGA debug LED stays open, white color. And hungs there.

All 3 GPUs tested had their fans working properly while the computer was powered up and the VGA light was white. All 3 GPUs were tested on another motherboards and work properly.

Should I consider the Motherboard pci slot broken?

its a 50/50 what it could be as there is 2 suspects.

1: Bad Motherboard Slot or board
2: Bad CPU that has a Defective PCI-E controller

its hard to say which of the 2 it is but the board is the more likely and if a board swap changes nothing then its the CPU at fault

About the original issue. After contacting thw seller, the Motherboard was returned. The technician found no problem with the motherboard and performed a bios update. Once I received back the motherboard with the updated bios it booted properly, recognizing the GPU.
