Dissable onboard graphic card

[Idonnowmaneim]

Hello. My problem is that i bought a AMD FirePro V5900 and when i put it on my pc, theres no image, but the graphics card and the pc turns on normally. I think its the onboard graphics option in the bios. But my problem its that i can´t dissable it because my bios doesn´t have this option. My question is: How i can dissable the onboard option without use the bios???pls i need help

Welcome back to the forum.

You may have to enter the BIOS to Disable Secure boot and enable Legacy support.

Instructions can reviewed at this (Link).

Make sure you connect the monitor to the new graphics card instead of the onboard graphics port.

I have done this many times.
