Question Motherboard does not recognize GPU

[tiaodasolda]

Hello everyone, I recently bought a Biostar B450MH motherboard because my Gigabyte B350DS3H had problems and had to be replaced. However, this new motherboard does not recognize my video card. I went to Biostar support and they asked me to go to GFX Configuration and set the Primary VideoDevice to IGD and Surround View to Auto.
However, I did not find these options in the motherboard BIOS.

To make it clearer, I have 4 GPUs with me that are fully functional, but 2 of them do not work on this motherboard and the other 2 do work. So, if I send it in for warranty, they will probably install a video card that will work and send me back the defective one.

CPU: R5 2600
Motherboard: Biostar B450MH
Ram: 16GB
SSD/HDD: 1 SSD 120GB / 1 HD 1TB
GPU: RTX 2060 Galax / RTX 2060 Zotac / RX 570 XFX / GT 1030(Galax RTX and RX 570 don't work)
PSU: XPG 750W

Did you reinstall the OS after the motherboard swap? Did you also see if your motherboard is pending any BIOS updates?

PSU: XPG 750W
How old is the PSU?

Thanks

I ran the tests without the OS installed, just the kit (motherboard, RAM, CPU and PSU).
The XPG 750W was purchased in November 2021(3 years).
Current BIOS is B45CS421.BSS from 04-21-2023
There are 3 update options.
B45CS919.BSS(AGESA ComboAM4v2 PI 1.2.0.B) from 09-19-2023 / B45CS304.BSS(Improve system stability) from 03-04-2024 / B45CS819.BSS(Update AMD AM4 AGESA 1.2.0.Cc BIOS ( Beta )) from 08-19-2024.

*Edit: I updated the BIOS for the B45CS919, I'll test it here.
*Edit2: Regarding the Bios update, the problem persists in the same way. I left it for more than 20 minutes without the CR2032 battery to reset it but it did not solve the problem.

Did you disconnect al the power to MB when taking battery out ? To see if taking battery out worked, check date and time in BIOS , it should have reset to initial date,
In some cases, they may be recognized only by Windows or other OS when drivers are installed. Use at least some bootable Linux distro from a USB.
