Intel graphic conflict with dedicated graphic card

[JoanK16]

I had problem with my AMD RX6400 graphic card and I found out it is conflicting with intel UHD graphic driver.

When there is intel uhd graphic 730 driver present, my GC doesn't start correctly and shows code 43 error.

Computer boots normaly only when I uninstal intel driver before turning off so I can use my graphic card.

The problem is, windows keeps loading intel driver automatically, so if I don't uninstall it again, my PC goes black again next time it boots up.

Can you please help?

Can you please provide the make and model of the PC? Or the make and model of the motherboard if you built the PC yourself.

It's IdeaCentre 5 14IAB7 - Type 90T2 from Lenovo.

Yes, the Intel Core i5-12400 includes integrated graphics, so if you have a dedicated AMD Radeon RX 6400 graphics card installed, there is a possibility of conflicts.

I would recommend disabling the processor's integrated graphics in the motherboard BIOS/UEFI.

• Restart your computer and press the appropriate key to enter BIOS/UEFI (usually F2 or Del)
• Navigate to Devices and find the Video Setup option.
• Change it from Auto to PEG (PCI Express Graphics).
• Save and Exit (F10).

Please also see this support article from Lenovo where you can find explanatory pictures:

Please note that you must first connect the monitor to the motherboard, i.e. the integrated graphics port, in order to be able to see the BIOS/UEFI. After switching to "PEG" as described above, connect the monitor to the dedicated graphics card. If you want to access the BIOS/UEFI again in the future when the system starts, it will be displayed there.

Thanks for detailed reply.

Strangely, this is what they say.

I've also noticed when I connect to integrated graphics, it just boots windows no matter what you press.

Lenove has some very strange and inconvenient settings for their PC.

In order to access to Bios, I have to plug monitor to Pcie video output but when I open its Bios, it's very simple and there is no option anything related to graphic device.

Maybe I should focus on disabling automatic internal graphic driver install instead.
