Method for disable the onboard graphic for p8z77-v motherboard

Hello,

i have problem with my graphic card (GeForce gtx550 Ti direct CU Top). It cannot be detected. i cannot see it in the device manager.
My motherboard is p8z77-v.

I had try several method. i reinstall the OS. I update the BIOS revision. I disable the on-board graphic in device manager.
But all seem not work. I found that when i change the setting in BIOS for graphic configuration from Auto to PCI-E and i save it before exit. But It automatically change back to Auto when i re-login to BIOS to confirm. So funny. Can someone please advise how to do so that OS can detect my graphic card? Thanks.....

  1. have you installed the gpu correctly(includes the 6 pin power connector). have you tried using the other pci-e slot on the mobo as well(even if its 4x, at least its a way to test if the card is dead or not)
