OK. Now change your graphics card.

It's already working, thank you my friend

Try to change Advanced->PCI Subsystem Settings->PCI ROM Priority from EFI Compatible ROM to Legacy ROM.

If it's not available in BIOS then try to change it in EFI GRUB Shell
1. Take USB stick and format to FAT32
2. Create directory structure EFI\Boot
3. Download and unzip bootx64.7z
4. Put BOOTX64.EFI to Boot directory.
5. Boot from this USB stick
6. Run command:
setup_var 0x21 0x0
7. Make and post a photo of the screen.

I did the EFI Grub Shell

When I changed my graphics card, my pc did show display but in integrated graphics, when I put VGA and DVI, it's not showing in my graphics card
