Graphic card cannot detect by motherboard P8z77-v

[Richard_thf]

i just build my first new PC. but my graphic card (GeForce GTX550 Ti Direct CU Top) did not detected by my OS. I cannot see it n the device manager.

I had try re-install my OS. I had try disable the on-board graphic in device manager. I had try update my BIOS revision. All cannot work!!!!:-(

For one thing strange is that i try to change the primary display in BIOS from auto to PCIE and save it before exit.
But when i re-login again to BIOS. It show back the setting to Auto. cannot understan why.


Anyone please help me to sovle my problem...

Thanks,

It sounds like the graphics card is dead. do you have another computer you can test the card with?
