Uninstalling old graphics card drivers

[ontotheland]

I used Intel g4400 cpu and integrated graphics.

I bought gtx 750 ti and I just put that in the expansion slot without knowing uninstalling old graphics card drivers.

And my monitor only showed a horizontal bar blinking at the top left corner with a black background.

I searched and found I should have uninstalled the old graphics card drivers. So I lifted gtx 750 ti out and did reboot. But my monitor showed the same blinking bar.

I could go into GIGABYTE BIOS and found that I can disable internal graphic.

Should I disable internal graphics and reinstall the dedicated graphics card or is there a way that I can uninstall old graphics card drivers?

Integrated graphics are separate from add-on graphics drivers, don't ever uninstall them.

When adding a gpu, you need to install the correct drivers for it. That's all. You should have installed the drivers before adding the card

Bios won't allow you to disable integrated graphics if it's the only source of graphics. When you add the gpu, all that needs doing in bios is setting PCIE or PEG as primary.

What do you suggest given this case I can’t go in Windows with my integrated graphics?

‘Initial Display Output’ in BIOS is PCIe 1 slot. So I think this part is okay.

Just place the new GPU into the system and download the newest drivers directly from Nvidia and your done, there's absolutely no reason to disable the iGPU. Make sure your monitor is connected to the GPU and not to the monitor.

I tried again. This time it worked.
I don’t know exactly why, but thanks for your answers.
